As always K&N provides a great product and 5 Star Service. I wish there was a way to give them a “10”. I have never had any issues with K&N filters or cleaning of them, I have heard some people complain about the price and/or the wait time if any. I always explain that on some new vehicles that they have to be made, “you might be the first person asking for a filter”. As for the pricing of the filters “ You are buying a product that will last the life of your vehicle is that not worth the extra money? “. If anyone has questions please let them ask.

On the 2015 model Aygo the filter gives an incredible acceleration! I can spin the tires, no way on the AOM filter! I get 10 -15 more Miles/hour speed on this filter compared to AOM that Toyota uses. Bravo K&N and thanks a lot to develop such wonderful filters. I had on Miata and soon on a Boxster S 2014 315 HP.
