Ok I have a Ef ? I have a B16 in a Ef body shape. Now which cold air intake can I us? Meaning which year intake can I use on this car, keep in mind that the battery is in the stock position. I have seen some ppl relocate the battery in other places(in the trunk) when they swap the B16 into a Ef.

 

I believe you would just use the same intake as you would for an Si. so it would be an 88-91 Civic Hatch Si intake. I think this is the way it works at least, correct me if I'm wrong

i have an aem cold air intake for a crx si on my b16ed crx hf. works great. some people like to get the SI intake though, and relocate the battery.
