Customer Reviews

It Fit's!
They sent the right one first time. Have not checked my mileage yet, I am keeping my fingers crossed.

K&N Filter
Filter fit nicely, not much increase on mpg however under load seems to have more acceleration, main reason for changing to filter was the fact that you can clean and reinstall which with fuel costs and the push for doing more maintenance such as changing the air filter more often the filter will pay for itself quickly, I also got the cleaning kit on my initial purchase

Realy great air filter
I recently bought a new 2007 Chevy Silverado. A friend told me about K&N filters and suggested I get one for my new truck. I did some research on the Internet, at the K&N web site and other places, and decided to go for it and ordered the filter from Amazon.

Chevy trucks are known to hesitate just a fraction of a second when you hit the accelerator. My new truck was no exception, but as I have driven Chevy trucks for 20 years I was used to it. Immediately after installing the K&N filter, to my amazement, the hesitation was gone. There was also a slight but noticeable increase in power.

I'm very impressed with the performance increases I have seen just from replacing the factory air filter with this superior product.
