Customer Feedback

The install took a little longer than I was expecting but going from a Honda to a Lexus IS quite different and I'd use the same method for install if I had to do it again. Kinda bummed out that the cleaning kit did not come with the intake for the price I paid for it, seems like they could have thrown that in. The intake itself has increased a noticeable amount of torque in acceleration . It's a low growl under 2500-3000 rpms but once u hit about 40 mph u can tell the difference and a bit of growling sound that will give your v6 a new place in people's hearts cause they definitely stop and look, it's priceless on the freeway above 60 mph when you have a distance to travel. I would recommend this product to anyone, Thanks K&N!

I have been using K&N oil and air filters for years now in my Lexus. And I have found it to be the most excellent of all oil and air filters. I commend K&N for their reputable products.

Four new cars in the last ten years and everyone has been fitted with the proper K&N air filter. Performance improvement was achieved in each car and each person who purchased my cars thanked me for taking care of my car and its engine. I recently purchased a new Lexus 450h and checked with and received confirmation from 3 Lexus mechanics that replacing the factory air filter with a K&N was the best possible move to insure long lasting performance.
