Alright. I know you can do this FC's, but im wondering, can you do this with the FB's aswell?

If so, any pics?

I did a search and got only 2nd gen pics.

 

if you have a 13b with FI you can, but not with a carbed 12a, well you could but it wouldnt yield any power on a 12a.

 

Sorry, should've mentiond, I have an -SE.

 

no yeild any power on a 12a!!!!! yes you can if you have a K and N air filter and chop up the canister on the 12a there are significant CFM differances in stock and chopped Rx7Carl flow tested this. When I did this I noticed a difference in my cars in all rpms. Too answer your ? if im not mistaken it is the same as S4 basically a MAF adapter plate bracket and a filter and clamp or you can mod the staock box by cutting the top off and dropping a k&n stock filter replacment in it.
