my buddy has a rsx type s and we were wondering if he got the rbc manifold from the civic, if he would need to order a cold air intake for the rsx, or for the civic since were using the civic manifold?

 

still a rsx one. because if you actually look at it the size on the rbc is a little bit smaller so everything should still fit. i know some box type intakes dont fit but the cai should..

someone correct me if im wrong.

 

If you took the RBC from the Civic, you'll need to do some modification. + The Karcept's adapater for your throttle body. It'll take some time to messa round a bit with it.
It's just a PITA. ClubRSX sells the kit complete and ready to put on.
