Easy to install and the perfect fit. My SUV runs smoother and has more guts. I have used your filters in my other vehicles with equal success.

This is my second K & N, first one was for the motorcycle. Hoping for an increase in performance and mileage as others report. Its hard to tell on the Camry Hybrid in the winter.

Just installed it on my wife's 2015 Avalon Limited Hybrid car only has 3,000 miles on it. However, it made about a 2 to 3 mpg difference in her 2008 Camry Hybrid XLE so I figured it would hopefully do the same for the Avalon.This is the 5th car we have equipped with the K & N air filter, we have also ordered one for our 2005 Prius and one for my new 2016 Mustang GT Premium convertible. Forget about the gas savings, normally the engine air filter gets replaced every 2nd or 3rd oil change so after the 3rd air filter replacement, the K & N air filter is FREE for the rest of the time you own the vehicle. I normally keep all my vehicles over 200,000 or until they start flunking smog so you can see the definite financial advantage of the K & N that most people do NOT think about.
