Im planning on putting a ram air not cold air into my 88 CRX that has a 89 ZC engine in it. Do I buy a intake for the crx or for an integra, I'm guessing for a CRX but I dont know the difference in the throttle body.

Who has done it and are there any special modifications I need to do?

 

buy the one for the CRX. throttle body is the same.

 

I have a Civic Si K&N Typhoon intake in my ZC'd '91 Civic Si; it fits better
with the ZC than it did with the D16A6.

good luck
