I have had nothing but issues using the K&N filter in my AMG! The oil will wreek havoc with your intake sensors. After a failure on the Benz. I chose not to go with K&N in the bimmer. I went with afe dry filter and have had no issues. The K&N's work fine in my Gmc and Jeep but you need to read up on problems associated with use in european auto's. My repair bill was over 1,100. For a 49.00 air filter with oil. Steer clear. Also look up the issues K&N's have caused with Volvo's.
