I just recently bought a '91 Civic DX, and while i was looking for parts for it I noticed that the CRX is listed beside the Civic on most product descriptions. Does this mean that parts made specifically for the 90-91 CRX will fit on my 91 Civic DX? For example, if i see an AEM CAI for the 90-91 CRX (not SI or EX) and its not produced for the Civic, could I make the CRX CAI fit on the Civic without serious modifications? Sorry if this is confusing, I've never had a Civic before.
