K&N 33-2139 Air Filter Product Reviews

Installed in a 1999 Jeep Grand Cherokee. A perfect fit replacement for the old throw-away filter. The Jeep air filter box is easier to open than the one on my Mazda Miata. The Mazda was the first K&N filter I bought and it was great - real performance improvement. The Jeep is no sports car and with only 4.0 L and a moderately heavy SUV, I need as much performance as I can get. A good investment for cars I intend to keep a long time.
