Revive your K&N Cold Air Intake with a K&N Cold Air Intake Replacement Filter. The heart and soul of your cold air intake is the filter, and an oiled cotton-gauze K&N Filtercharger is guaranteed to restore your system to its former glory.

By reducing restrictions, K&N filters boost horsepower, torque and throttle response. And while your K&N filter is busy letting the power in, it's keeping engine-killing crud out. Deep pleats and tacky oil trap the dirt—multiple media layers let the power-producing air flow right through.

Washable and reusable for life, your K&N replacement filter could be the last filter you buy. Better yet, get an extra replacement filter to make scheduled cleaning even easier. While you're cleaning one filter, the other's in the vehicle, ready run.

Designed to fit any K&N Cold Air Intake, these replacement filters also fit other brand intakes—so upgrading to the World's Best Air Filter is a snap. Best yet, your K&N Cold Air Intake Replacement Filter is backed by a Million Mile Limited Warranty.

K&N has one of the best air filters on the market I have run them on motorcycles and cars and trucks for decades the easier you get air in and out of your engine the more power you can develop plug up one of your nose holes and try to breathe that's what I'm trying to explain one nose hole plugged is your factory system acts like let them both open that's how K&N works get it I hope so they make great products for the power guys and gals
