Best filter you can get for your car. I highly recommend K&N.
Don Booth, Portland, Oregon
This is the 3rd vehicle I have installed a K&N air filter in. Every vehicle has benefitted from an immediate increase in power, not a huge increase, but assuredly noticeable. None of the vehicles however have had increased gas mileage due to the filter and I don't care about that. Give me horsepower! Great product and I've not had any issues with them.

Online order was easy, arrived quickly. Superior filter, noticed almost right away an increase in acceleration. Looks also that there is a noticeable improvement in fuel economy. Quality product, looking forward to trying more K&N products.
