I have used K&N air filters for years and have been satisfied each time I have bought one.

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.
