Works great. Been using them for years on both motorcycles and cars.

I have used K & N Filters for many many years in various cars, trucks and rv's. This filter for a 2015 Toyota Avalon, V6, is one half the thickness of a stock filter. I called K&N Filters about the difference and they claim that thickness did not matter because of the material used in their filter compared to the stock Toyota filter. I hope Toyota agrees with them.

From the minute I installed my K&N Filter I noticed an immediate difference in throttle response. No more turbo lag and quicker acceleration. The horsepower increase was the biggest surprise and the easy installation is well worth a small investment. After the first day with my new K&N filter I got back on the computer and ordered one for my Wife's car. The savings on those bulky performance stealers far out ways the investment in a K&N filter. Im sold for life...
