I only use K&N filters in my cars. They are the best filters made. Shopping at KNfilters.com is as easy as breathing.

First thing we replace, with every vehicle, we have ever owned since K&N has been around. Next time we will mess with our filter will be 50 K miles. Clean & re-oil, how can you beat that.

I just received and installed this new engine air filter and K&N asked me to rate the product. So far it fits well in the air box and has not thrown a CEL (2 weeks/500 miles). Did not notice any inconvenience so far. Purchase experience was great with fast shipping. This is the 10th K&N replacement filter (for 10 different vehicles).
