I have a 1988 CRX HF with a B18C5, and have relocated the battery to the trunk. I'm looking for some 3" CAI piping since I will be road racing this. Some people said go with a 99-00 Civic SI intake, others said stick with a CRX one that is straightened out since I don't have to go around a battery. I was hoping for just some ebay or at least under $100 3" intake piping. I will be using a K&N 1048 with a BSi velocity stack, that's why it's gotta be 3"

 

yea go with the 99-00 Si cold air intake...fits perfect when your battery is relocated

 

Which one exactly? AEM, which is rather expensive, makes at least 4 CAI designs for a 99-00 Civic SI. The straighter and the cheaper the better. Any pics?

bump, hopefully someone knows by morning...

 

i have bought a bunch of cheap EBAY intakes that are actually 3" diameter. for a CRX also.
the 99-00 civic si intakes have extra holes and bungs in them.


OBX for 92-95 civic. super clean.... only has one bung too.

 

Well I got an EG intake, and all is well, but it is just under 2.75", and I need 3" for the velocity stack. Anyone know where I can get a definite 3" tubing? I dont even need the filter.
