Great fit, easy to install. The best part is the kids at the oil change place don't bug me to buy an air filter every time I visit them. Gas mileage improved slightly. I'm happy with the product.

We have a 2007 Prius with over a 100,000 miles on it. I installed a new K&N air filter and the MPG picked up 1 mile after the first tank of gas. I have had K&N filters on all of my past cars and trucks, and my brother has now started to use them also.
