I gotta say, this forum rocks!! Already have seen lots of useful info here that I couldn't find anywhere else. I reviewed the custom cold air intakes for the 91-93 2.3L. Okay, I'll admit that's more than I want to bite off right now (Yea, I'm a wuss). My question is what the heck is that fat ribbed section of the intake between the the air sensor and the manifold?? It looks like some kind of baffle or silencer; if so it would impede air flow to some degree. One could easily replace that whole section (sensor to manifold), if it would be of any benefit. Any thoughts on this?? I've already installed a K&N in the stock air box, and am pleased with the results. I'm just looking for any easy (and likely subtle) improvements that can be made. Just think of it as modding for dummies. Ive got a 92 convertible 2.3 5 sp, and have upgraded from the stock 14's (yuk) to BFG 15's with 87-90 GT turbine wheels (E-Bay). Not exactly a dyno buster, but I just wanted a cruiser anyway. Thanks for any help!!!!
