Okay, I've finally finished it. I bought the Jam engineering adapter. As someone said, it's fined aluminum, matches the valve cover and looks great. I got the one with the single oval intake, 2-1/2"x2". I don't know how to calculate flow area for an oval, but I'm speculating that it will flow enough for a 4 banger. I then found a 2" rubber plumbing coupler from Home Depot that fit the oval good with a clamp. I bought 3" air intake flex hose, a 3"OD x 5" piece of exhaust pipe that fits through the factory hole. I bought a K & N type cone filter that fits in front, and it wedged in so well that I didn't even need to build a bracket to support it. I had planned to order a K & N universal filter, but found this one at Auto-Zone and didn't want to wait. I guess it is for the Rice Boys, but it's way large so even if it doesn't flow as well as the K & N, it's still over kill. The front of it is also a concave air inlet. It has a 3" opening so it fits on the exhaust pipe nipple perfectly. I'm gonna try to attach a pic....sorry 3 tries..I'm out
