K&N air intake systems come with a 10-Year/Million Mile Limited Warranty | Engineered for 2018 Jeep Wrangler JL 3.6L V6 models, the 63-1576 K&N® performance air intake system offers a guaranteed increase in horsepower and torque for Jeep Wranglers—and features a washable, reusable High-Flow Air Filter™ to help protect against damaging engine contaminants. In addition, the enclosed air box is designed to provide additional protection during challenging off-road adventures—and can help protect your filter during water crossings. The 2018 Jeep Wrangler JL has been fully redesigned—and it shows. With nearly unbeatable off-road capability for its class and advanced tech features, the new Wrangler is engineered to help you tackle your adventures off the beaten path with ease. K&N PERFORMANCE AIR INTAKE SYSTEMS BOOST HORSEPOWERIf you want to give your Wrangler a little extra “oomph”, check out the 63-1576 performance air intake system—specifically designed to fit in the engine bay of 2018 Wrangler JLs. The 63-1576 is designed to keep engine air cooler (which can increase engine combustion efficiency), and provides a smooth, low-restriction path for airflow to the engine. Many stock intake systems have airflow-obstructing components that can create turbulence—and thus heat—resulting in less efficient combustion, and giving you less horsepower. By replacing the complete factory system with an aerodynamic tube and High-Flow Air Filter™, your engine will have access to a higher volume of cool air—giving you a guaranteed increase in horsepower and torque. AERODYNAMIC INTAKE TUBE INCREASES AIRFLOWTypical factory air intake systems force air through a restrictive disposable paper air filter before the air travels through a complex system of tubing—which often has tight bends, baffles, and other elements that can cause swirling, turbulent air. Excess turbulence can cause the molecules within the air to collide, which creates heat—and an increase in temperature reduces the density of oxygen molecules in the air. Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. 
The 63-1576 for the 2018 Jeep Wrangler JL features a High-Flow Air Filter™ | The 63-1576 intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to reduce turbulence in the air, keeping engine air cooler—and increasing engine performance! An incorporated radius adapter allows the filter to mount directly to the intake tube, which reduces hardware and helps increase ease of installation.HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTIONMost factory disposable paper filters only “surface load” contaminants—collecting them on the surface of the media, which over time can reduce the filter’s efficiency due to clogging. Alternatively, High-Flow Air Filters™ “depth load” contaminants; multiple layers of cotton fibers capture particles on many levels. Because the contaminants are incorporated into the filter fibers, the filter can still operate without significantly reducing its efficiency. Additionally, the layered, pleated design of the filter media increases the surface area of the filter—providing significantly more contaminant capture per square inch of media over a standard paper filter. The High-Flow Air Filter™ included in the 63-1576 intake kit is oversized (625 square inches of media) with a conical shape, providing a greater surface area and allowing for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). High-Flow Air Filters™ feature an oiled, layered design—providing up to 50% more airflow over a disposable filter. When your filter does need to be cleaned, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each K&N intake (and filter!) is designed to last for the life of your vehicle. AIR BOX HELPS PROTECT INTAKE AIR AND FILTERThe 63-1576 features a high-density rotationally-molded polyethylene air box, which helps protect the air filter and intake air from high engine temperatures and directs airflow into the throttle body. The enclosed air box design helps create a barrier against dust, dirt, and moisture—all of which can be present in rigorous off-road environments—and is designed to provide additional filter protection during water crossings.

| You might be wondering—what’s the best way to add horsepower to my vehicle? Aftermarket modifications like bolt-on superchargers and turbochargers can add significant horsepower, but are often very expensive—typically in the thousands of dollars—and can take considerable amounts of time and mechanical prowess to install. 
K&N performance air intake systems add horsepower and torque to your car | That’s where K&N performance air intake systems come in—giving you a guaranteed increase in horsepower without the hefty price tag of a supercharger, and typically in less than 90 minutes for installation.How does an engine make power?An internal combustion engine operates by burning a mixture of fuel and oxygen within the engine’s cylinders. The fuel injectors provide a precise amount of fuel, which combines with air delivered by the air intake system. A spark plug then ignites the volatile gas, creating an explosion that forces the piston downward—turning the crankshaft. The piston-moving force that’s created during the combustion cycle is what produces horsepower. How do factory air intake systems work?Your engine needs oxygen to create power. The cylinders in your vehicle’s engine have to have air to create the explosion that produces horsepower and torque. Since cold air contains more oxygen molecules than warm air, injecting a higher volume of oxygen-rich air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power. In a typical stock air intake system, air has to pass through a thick, disposable paper filter, and then move through a narrow system of tubing that can cause air to swirl and become turbulent. Excess turbulence causes the molecules within the air to collide, creating heat, which lowers the density of the air and reduces the efficiency of combustion. Factory systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow and create turbulence. These systems are also typically designed to muffle engine noise—unlike K&N intake systems, which are designed to give your engine a more satisfying growl. 
Disposable paper filters often feature thick media that restricts airflow | Why is airflow so important for my engine’s performance?Maintaining the proper air-to-fuel ratio (AFR) is critical for engine performance, and relates to the amount of air versus the amount of fuel used by an engine for combustion. A correct, stoichiometrically balanced AFR produces combustion with perfect efficiency, excluding other factors. For gasoline engines, the theoretically perfect chemical ratio is 14.7:1—14.7 parts air to one part fuel. In effect, this means that an engine requires almost fifteen times more air than fuel for efficient combustion—which emphasizes the importance of providing a high volume of air through an intake system. Why not use a disposable paper air filter with my intake system?Most dry, disposable paper air filters function on a size-dependent basis—dirt particles that are larger than the openings in the filter media are trapped, while particles that are smaller than the openings pass through. Most disposable paper filters create a large amount of airflow restriction, as the openings in the filter media have to be extremely small to filter efficiently—which slows down airflow. Because dust accumulates on the surface of the disposable filter, performance typically decreases consistently throughout the filter’s service interval. Why is a High-Flow Air Filter™ better than a disposable filter? 
High-Flow Air Filters feature a specially designed cotton media | A paper filter exhibits a principle called surface loading; dust collects only on the surface of the media. In contrast, K&N High-Flow Air Filters™ utilize depth loading, where multiple layers of cotton fibers provide particle retention on many levels, and the media also features pleats to increase the contaminant-capturing surface area. As a result, K&N filters are able to hold significantly more dirt and particulate matter per square inch of media over an average paper filter.In addition, High-Flow Air Filters™ utilize the principle of diffusion to increase the capture of engine contaminants. Small particles are highly affected by forces within the air stream, such as velocity changes, pressure changes, or turbulence. As a result, the behavior of extremely small particles is typically random and chaotic. These particles do not follow the air stream, and their erratic motion causes them to collide with the filter’s fibers—where they are trapped and held by oil. This enables a K&N air filter to capture contaminant particles that are much smaller than the openings within the filtration media. Is a K&N performance air intake system better than a stock system?K&N performance air intake systems are designed to create a more aerodynamic path for airflow to reach the engine by removing the stock intake tubing that can create excess turbulence, and also by utilizing highly airflow-efficient filter media. 
All K&N performance air intake systems are tested on a dynamometer | In a K&N cold air intake system, air first passes through a performance air filter—typically a High-Flow Air Filter™, which is designed to provide up to 50% more airflow than a disposable paper filter—and then passes through an aerodynamically-engineered tubing system that helps prevent unnecessary turbulence/heat.Cold air is more dense than warm air because it contains additional oxygen molecules—allowing the cylinders to facilitate combustion more efficiently. A factory air intake typically feeds warm air to the cylinders, while K&N performance air intake systems are designed to provide a smooth, unimpeded path for the airstream—keeping the airstream cooler and more oxygen-dense. With a K&N performance air intake system, you get a guaranteed increase in horsepower and torque. Which K&N intake system should I choose?All K&N performance air intake systems are designed to increase airflow through an aerodynamic path that reduces turbulence, and filter designs that provide an increase in the volume of air that reaches your engine. K&N offers several options to cater to different aesthetic, ease of maintenance, and filter media preferences.

| Whether you’re planning a short weekend trip to your local national park—or an extended cross-country road trip—you can help avoid unexpected roadside headaches by performing thorough pre-trip maintenance on your RV. Taking good care of your home-away-from-home will help you enjoy your vacations for many years to come! 
Ensuring your brakes are in good condition is critically important | CHECK YOUR BRAKESCheck for any brake fluid leaks, and make sure the reservoir is filled to the recommended level. If you’re towing a heavy load, your brakes have to work even harder, particularly on steep inclines. When looking between your wheel’s spokes, you should be able to see at least one-fourth of an inch of pad—any thinner than that, and you should have them inspected and possibly replaced. EXAMINE YOUR TIRESYour tire treads should be in good condition before any trip—generally speaking, less than 6/32” of tread depth indicates that your tires should be replaced, as well as any cracks that are deeper than 1/16”. To extend the life of your tires, check to make sure your tire pressure is always at the manufacturer-recommended level, and rotate your tires regularly according to their recommended service schedule. Long periods of storage and long-term exposure to sunlight can accelerate tire damage. 
Planning ahead helps you have peace of mind on your travels | Keep an eye out for weather cracking, which will appear in the flex area of the sidewall. Now is also a good time to tighten your lug nuts, and make sure you have what you need to change a tire in case of a flat.INSPECT YOUR COOLING SYSTEMOverheating on the open road in the middle of summer isn’t just a temporary headache—it can cause permanent engine damage. While your engine is cool, take a close look in your engine bay. Cracks or leaks in hoses and belts indicate a need for immediate repair, and make sure all connections are snugly fitted. Fill your coolant reservoir to the recommended level (a 50/50 mixture of coolant and distilled water is standard). If it’s been more than two years since your last full coolant flush, you should consider completely replacing the fluids. CONSIDER A BACKUP CAMERAA backup camera helps take the guess-work out of navigating tight spaces and hitching up trailers—and also increases safety. Even the most seasoned drivers can benefit from an extra pair of eyes in their blind spots.

If you have a cabin air filter, check out K&N’s washable line, which helps protect your cabin and passengers from airborne dust and contaminants. To search for filters for your specific vehicle, check out knfilters.com. CHECK YOUR FULL ELECTRICAL SYSTEMExamine the electrical cord that connects your RV to a park power source, and check for any signs of damage. Also, take a look at your circuit breakers and fuse boxes, and make sure they’re labeled. If you’re towing, make sure the electrical connection is set up properly. ANALYZE YOUR BATTERIESBatteries can lose a considerable amount of charge while in storage, so make sure your batteries are fully charged before any trip—and watch out for any corrosion. Always refer to the manual when adjusting water levels, and be sure to wear eye protection. FLUSH YOUR WATER SYSTEM + CHECK FOR LEAKSIt’s a good idea to sanitize your water system every time you take your RV out of storage. Can you imagine what grows in a moist water system that’s left to sit in storage for months? You probably don’t want to. Bacteria, mildew, and mold can proliferate in a water system that’s left to sit—and you want the water you bathe in, cook with, and drink to be clean. Steps to sanitize your water system:• Drain the water heater (never drain while hot or under pressure) • Locate and drain the water from the low point water line drains—one for hot and one for cold water lines • Drain the fresh water holding tank • Close all of the drains • Use ¼ cup of bleach for every 15 gallons of water your tank holds—mix the bleach with water in a 1-gallon container and pour into the water holding tank (do not pour straight bleach into your tank!) • Fill the fresh water holding tank almost full of potable water • Turn the water pump on, and open all faucets • Run all of the faucets until you smell bleach at each faucet • Close the faucets • Let sit for around 4 hours • Drain the entire system again—re-fill fresh water tank with potable water • Run all faucets until you no longer smell bleach (you may have to drain the system multiple times to remove all bleach from the system) • Once you no longer smell bleach at each faucet, your water system is now clean! You can check for leaks by grabbing a flashlight or headlamp and turning on your water pump. Wait until the sound of the pump stops and the water is pressurized. Turn off the pump, and begin looking for leaks—around the toilet and under the sink are good places to start. TEST APPLIANCESCheck each interior appliance to make sure it is in good working order. Test your water pump, furnace, air conditioner, and all lights and outlets. If you use propane (LP gas), check your tanks (these can expire), all connections, the valve, and the firing operation. If something seems off, have a professional examine the system. SERVICE YOUR GENERATORWhen pulling your RV out of storage for the season, follow the directions for servicing in your generator’s manual. Before starting it up, make sure the oil is at the appropriate level, and check for any problems around the exhaust. Run the generator for at least two to three hours every month to keep it primed and ready, as fuel that sits too long can cause damage. 
Follow your manufacturer’s recommended service schedule for oil changes | CHECK ALL FLUIDSCheck the levels of your transmission fluid, power steering fluid, engine coolant, engine oil, windshield washer fluid, brake fluid, and generator oil. If any fluids are suspiciously low, make sure to check for leaks. Regular oil changes help prevent unnecessary wear-and-tear on your engine. INSPECT SEAMSAt some point in your RV’s lifespan, it will probably experience a leak or two in its roof seals and/or seams. It’s important to know the type of material that your RV’s roof features, and bring along compatible repair sealants on every trip just in case. Sealants will vary based on the RV’s material—silicone, for example, won’t bond with a rubber roof. Regular household caulking may or may not hold up long-term, but can work to plug a leak in a pinch. Water damage can be seriously expensive, so plan ahead for on-the-go repairs. With a bit of forethought and careful maintenance, you can help avoid mid-trip repair fiascos, increase your RV’s performance, and enjoy well-planned vacations for years to come!
