Very pleased with the product and was very glad they had one for my 2015 Toyota Rav4 XLE.

This filter is for a Hybrid. I thought I would save money by cleaning rather than replacing. I was not expecting any improvement of my fuel mileage. Boy was I wrong, I will now use your filters on all of our vehicles.

I am in my 3rd RAV-4 in 17 years. I have used K&N filters in all. In my new 2015 XLE AWD, I installed the K&N filter about a month ago. I have since observed a quicker response to throttle input. While now indulging in the heightened responsiveness, I am still experiencing my previous average in city mileage of about 20 - 22 mpg. This is in line with the improvement I was anticipating.

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.

K&N filters are well worth the purchase price. Engines run at peak performance.

This product is another winner from K&N. I can notice a difference in my 2013 Toyota Avalon Hybrid. I am seriously considering another K&N Filter for my newly acquired 2001 BMW Z (M). Already a rocket, why not make it even more fun?
