The K&N HD-9608 is a high-flow, washable replacement for the stock air filter element on Harley-Davidson Twin Cam Dyna models. It uses woven cotton gauze media layered between epoxy-coated wire mesh, with pleated media for extra filtration area and an application-specific base seal to keep unfiltered air out of the intake. It arrives pre-oiled and ready to ride, and the manufacturer says it is made in the USA.
Compared with a stock paper element, the manufacturer says this filter is designed to increase horsepower and torque, improve throttle response, and deliver longer service intervals. Because you clean and re-oil it rather than replacing it, the cost is spread over many service cycles, and the manufacturer lists a re-oil amount of 0.23 oz (7 ml). It also carries a No-Hassle Lifetime Limited Warranty. Check the fitment before ordering, since the manufacturer's listed years are 2008 to 2016 Twin Cam Dyna models, including Wide Glide, Low Rider, Fat Bob, Super Glide Custom, Street Bob, and Switchback variants. This is a good option for riders searching for a Dyna air filter upgrade, a Twin Cam K&N high-flow filter, or a Harley 2919108 replacement.
The manufacturer lists the HD-9608 for Harley-Davidson Twin Cam Dyna models from 2008 through 2016. Confirm your exact model and engine size against the manufacturer's application data before ordering.
Yes. The manufacturer describes it as washable and reusable, supplied pre-oiled, and lists a re-oil amount of 0.23 oz (7 ml) for servicing.
The manufacturer lists a No-Hassle Lifetime Limited Warranty on the HD-9608.
The manufacturer rates this as an easy, screwdriver-only job that typically takes about 5 to 10 minutes. No dedicated install sheet for the HD-9608 was found, so use the stock filter as a reference for orientation and seating. K&N's install sheets for other Harley filters stress that the seal must be correct every time the filter is serviced, or the filter may not seal and engine damage could result. Seat the filter fully, keep the sealing surface clean, and make sure the cover and fasteners go back on snugly without being overtightened.
