One of the earmarks of most of the Harley-Davidson® FL models is the large-framed classic styling they embody. That being the case, many FL owners prefer the stock look of their bikes. Now 2017 Harley® FL owners can enjoy the performance and protection advantage of K&N air filtration while retaining the stock air box and cover.

The K&N HD-1717 air filter is designed to give a boost in horsepower and torque to your 2017 107 CI Harley. It replaces the oe air filter, part number #29400212. The free flowing design is engineered to provide additional air to your V-twin. A reduction in intake restriction typically results in crisper throttle response for a more satisfying ride. Of course, your performance results will vary.

K&N’s rigorous testing of the HD-1717 reflects in an estimated overall filtration efficiency of over 98%. You are encouraged to click on the Air Filter Test Data link on the HD-1717 product page to see the protocols and filtration charts.

The application-specific filter body fits perfectly in the stock FL air box

The marriage of performance and effective filtration is what K&N is all about. The first line of the K&N test data page states, “Proper air filter design will accomplish high filtration without overly impeding air flow or engine performance through restriction.” Clearly, as is the case with all K&N filters, the HD-1717 is the embodiment of the performance and effective filtration design goal.

The filter element is engineered in a shape and form that perfectly fits the stock air box. The factory breather tube is incorporated just as it would be with the stock disposable air filter. The HD-1717 also features an application specific base seal and sealing bead to ensure an OE level of fitment. The installation is made simple with K&N’s installation sheet.

The washable and reusable filter is composed of pleated woven cotton gauze media that comes pre-oiled and ready to install. When it is time to wash and re-oil the filter, a K&N 99-5000 filter recharge kit makes the process simple and straightforward.
