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 purchase my first K&N air filter back in the late 1970's. I have tried other filter manufacturers over the years but keep coming back to K&N. The filters fitted perfectly in the plastic housing and straight away there was a noticeable increase in the pick up of the engine when you put your foot down. Excellent product as always.
