K&N’s washable and reusable High-Flow Air Filters dramatically improve airflow and the level of filtration. When combined with a good set of pipes, and some re-jetting or re-mapping, big horsepower increases are a definite.

K&N’s Oil Filters are constructed with a special Synthetic Media designed for ultimate flow, less pressure drop and enhanced filtration. They work great with the popular synthetic oils (and the petroleum-based oils as well), to resist break down, unlike the standard paper filters.
arley riders have been asking for K&N for, well, as long as most of us can remember. When a customer requests a high-flow/high-filtration replacement air filter element chances are good they’ll leave the counter carrying a K&N. A K&N High-Flow air filter, all by itself, can do wonders for a Harley. Combine that new air filter with a good set of pipes and a little re-jetting or re-mapping and the result can be phenomenal. A 20-, 30- even 40-percent increase in horsepower and torque isn’t unusual, and all of this comes from straight bolt-ons centered around that K&N filter. Those K&N High-Flow air filters will last the life of the motorcycle, too. They’re washable and reusable. Constructed with sheets of pleated and oiled cotton gauze layered between aluminum wire mesh, these filters actually straighten out and dramatically improve the airflow and the level of filtration. A K&N air filter–developed from decades of desert racing–is as familiar as it gets.
     A K&N Oil Filter is the perfect complement to all of that. A K&N Oil Filter does for the oil and the engine’s lubrication what that high-flow air filter does for the air it inhales. A K&N Oil Filter is almost a “race spec” oil filter. It provides 20- to 30-percent more filtration area than a standard OE or OE-replacement oil filter, and that’s just the beginning.
     The K&N oil filters use a special Synthetic Media, a resin-impregnated filtration material designed for ultimate flow, less pressure drop and enhanced filtration. And that Synthetic Media won’t break down filtering today’s popular synthetic oils, something that’s all too common with standard paper filters. Plenty of riders are switching to synthetic oils these days, but if they’re not switching to a K&N oil filter, too, they’re only doing half the job. Used with synthetic oils, a standard paper oil filter can end up filtering itself and prematurely clogging. Spin on a K&N when that synthetic oil gets poured in and the problem’s solved. And yes, that K&N works just as well with regular petroleum-based oils.
     A K&N oil filter has a heavy-duty steel body, too. It’s much thicker than any OE filter body and has a correspondingly higher burst point. For easy installations and removals there’s a handy 17mm hex nut formed right on the end, too, and that hex nut is even cross-drilled for safety wiring. The K&N oil filters have pressure relief valves where applicable (set to a higher PSI allowing the filter to do its job longer), there are anti-drain back valves (again, where applicable) and the K&N oil filter even comes with its base gasket pre-lubed for a tight, leak-free seal.
     Adding performance filtration is the best thing you can do for any engine. You know what a K&N High-Flow air filter has to offer. You’ve known it for years. Those other K&Ns, the Harley-Davidson oil filters, complete the package, especially when synthetic oils are involved. They’re available in either black or chrome, and Drag Specialties carries them all. Call your rep today.
