Très bon produit. Site très professionnel.
DJ Ehrlich, Rincon, Georgia
I have always been pleased with K&N products, for my vehicles. I have not been able to make the 1 Mil. mile claim yet, but I'm working on it. I would like to see more products for foreign made auto models, such as Audi, Mercedes Benz, etc. Such things as Cold Air Intake Systems, not just filters.

Ordered on the Monday, fitted by Tuesday morning. Very easy to fit, comes with very easy to follow instructions, plus a layout diagram for the car your fitting it to, if your not 100% how to fit it. It seems to have had the desired effect too, the engine feels slightly more responsive under acceleration, and the engine sounds a little throatier, which is nice because V6's sound awful when you rev them, this does it's best to hide the high rev whine.
