Definitely improved milage on my 2014 toyota 4runner. The buying experience was good. Shipping took a bit longer than most things I buy online but it worked.

Good quality. It's really worth having one. Another good thing about the product is it's made in U.S.A. and not in China.

Install was very easy. I have driven close to 2,000 in about 2 weeks since it was installed and have noticed around 2mpg increase in fuel mileage. Definite power increase while running A/C over standard air filter. Love it so far.

High quality and very nice product. It gives my rpm more responsive and gains some power and increase my mpg about 1 to 2 in my location. I recommend this product to anyone who wants to adds some power to their vehicle for a least expensive.

My expectations were very high given my previous experience with other K&N filters installed in my other vehicles. Excellent product that lives up to its promise of increased acceleration & overall improvement in power. Very fast delivery of item too. I received much sooner than expected in double box. Installed in a new 2015 Toyota 4Runner Trail making an excellent vehicle even better if that's even possible Hats off to the folks @ K&N
