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.

cleaning and re-oiling can be a hassle in cold weather climates because of the needed ventilation when cleaning/oiling the filter therefore I had to purchase a second filter to swap out when needed

The K&N filter fell off three different times (the K&N intake rocks with the engine, and it works the filter loose). The 3rd time it fell off, the filter would NOT go back on. The clamp was still in place and shrunk the filter tube to the point that no amount of heating, stretching, or wiggling would get it back onto the intake tube. I had to throw it away (it was destroyed by this point) and purchase a new filter.
