Customer Feedback

My wife has a 2002 BMW z3 and since easily fitting new K&N air filter 33-2070, the car is excellarating faster and smoother, rumble from engine sounds better. It's a 2.2 strait 6, so I bought one for my S type Jag, same results. I highly recommend this product and delivery, Allan.

Have filters, now, for our old 1987 F250 Ford truck, our old 1987 Mecedes Benz 300TD Diesel wagon and our 1996 BMW Z3.
We're happy with all three filters (so far...).

What can I say. K&N Rocks! I've installed K&N on everything from my BMW M3 to my Jeep Wrangler. Why not my new BMW F800 GS Adventure?
