After reading the thread on the K&N vs stock filter I went back to the stock filter but have 1 question. As I had the guys at the shop put it in when they did the oil change I didnt notice if the OEM filter uses a clamp to seal to the tube like the K&N does. When I bought the new filter the dealer gave me a new part number 19239713 which replaces the old number and it does not come with one and the one off the K&N is too small. It is a tight fit so does it use one?
