Hey all,

I currently have a junk SR on my car and its a 3" piece, which I recently learned isn't a good idea to have on the N/A F22...now I got a good deal on a AEM CAI (minus filter) and I'm just looking around for a K&N for it. However, I don't have the intake yet...is the piping on it 2.25, 2.5 or 2.75 inches? I've been looking around and it seems like all the size questions are related to the B series intakes. I know the Prelude H22 CAI is 3", but I'm just wondering if the Accord one is (which I think it should be) smaller...just by how much.

Also, I should expect to see a minor gain going from a 3" short ram and bad filter to a CAI and K&N, correct?
