This is my second purchase from K&N, the first being two years ago. Though the first product didn't work well in my vehicle at the time, I was very impressed with the customer service I received, and the attention of your staff.

I have had these filters in my Nissan 370Z for 3 years and I notice the little extra performance and nicer engine sound (even though it's only slight, I know my car and it's definitely an improvement). Never had any trouble with filtration quality. I can't speak highly enough of the customer service I've received using this website either.
