Product Reviews


  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?

  Fit perfect, I feel the difference! Thanks for a great product!

  K&N in all of my cars. I cannot corroborate the horsepower claims but the cars seem more enthusiastic. I also feel they give a level of protection not seen in regular air filters.

  WOW...what a difference having replaced the stock Toyota air filters with K&N replacements. I used the plural because the Lexus LS460 has 2 separate air filters. The car is an absolute BEAST having easily raised the horsepower to over 400+ while maintaining similar fuel economy. I'll probably get better MPG when I stop stomping on it just to feel the POWER! Replace the stock chip and void the warranty...absolutely no way. But changing the air filters (and NOT VOIDING the warranty) seemed way too easy. I was so impressed I bought new filters for my wife's GS460 and our Toyota Tacoma 4.0 V6. Both have dramatic increases in power and fuel economy albeit, she's having problems with not stomping on it as well. Who ever came up with this idea for passenger vehicles kudos! Can you do the same thing for HVAC units? I want to feel the polar blast save energy and make my wife a human pop sickle! With GREAT admiration....
