One stupid, stupid, stupid question... what kind of filter should I get? I am going to get a k&n, but I do not know what size to get. If anyone could tell me I would appreciate it. And if you are going to flame, i am sorry, i just want to make sure i get the right one. I have never bought a filter, so i dont know if there are different sizes or if all kn cone filters are the same (which I doubt). Thanks!!!!!!!!!!

 

I got a K&N with a 3" opening. I took my new midpipe section in to my local parts store then got them to get me a K&N that would fit. The one I got is not a cone but a cylinder.
Cheers,
Matt
