Everyone is saying that the K & N filter will not fit or is the wrong size??? I got mine when I got the Livernois tune and it fits perfect. The K & N number is E-2993. Not sure what number filter you have been trying but this one seems to be a direct replacement and fits right into the lower lip as well. It went right on with no problems. If you just want a little more power or more intake noise just remove the lid and run a strap across the filter to hold it in the lower lip. That way no oil contamination (if that is your worry). I have used K & N filters on all my cars and never had a problem with any of them but then again that is just my experience. I assume you know the new filters come pre-oiled so don't add more. That is only for when you clean them. You can see the pictures of my filter install in the above reply.
