If you are a performance auto enthusiast, then you've most likely heard the name K&N. K&N air filters are well-known to be one of the best-flowing air filters in the performance car market. And a performance K&N air filter makes a perfect first upgrade. Why? K&N air filters are economical since you wash them rather than replacing them--K&N even backs up their washability claim with a 10-year, million-mile warranty! Okay, economy is good, but what about performance? That's where a K&N air filter really makes a difference. K&N air filters flow much more air than a stock paper filter by using a special oiled cotton air filter element. Not only does this air filter element flow more air, but the K&N filter element actually uses dirt to catch more dirt as it's used--without a significant reduction in flow capacity. So, a K&N filter protects your engine with better filtration while providing more air flow and more power. What could be better? We stock a wide variety of K&N air filters to suit most import and domestic applications. And if you are thinking about taking things a step further, don't forget to check out our cold-air intake systems. The combination of a K&N air filter and a less-restrictive intake will really free up some hidden horses. So forget about replacing a restrictive paper filter every year--upgrade to a washable, reusable, high-flow K&N air filter today!
