I've always been a loyal K&N customer for my weekend drivers. I never really considered buying a filter for my daily driver but decided to give it a try. The shipping process is always easy, the filter arrived and was super easy to install, and I always appreciate the decals they provide to show when you open that hood that you have a K&N installed.

I replaced my old filter with this K&N filter and it runs amazing. I noticed that it even allowed my car to push a bit harder and reach 112mph rather than 110mph with a (Brand Name) filter from (Brand Name). My only regrets are that I didn't buy parts to make a short ram/ cold air intake using the right size K&N air filter for that instead. Sadly K&N also does not carry any air intakes for my 2007 ford five hundred. If they did when I made my purchase, I would have opted for a cold air intake/short ram intake.

I have used K&N filters in all my cars, trucks, and motorcycles for many years and I would not consider using anything else in my vehicles. EVER.

Noticed an immediate difference in power, and watching what will happen with fuel mileage.  So far, so good
