ok guys..i did a search but no luck..for a b16a engine, will upgrading to a itr manifold/skunk 2 manifold work or would it only be compatible for the b18c1 engine??

if not, should you just leave the stock b16a intake manifold stock?

 

itr will work for b16
skunk 2 will work for gsr (or you can get one for b16)

but itr will not work on b18c1 head. diffrent bolt pattern.

get an itr manifold.

 

Get the ITR Manifold. Its flow way better then the stock one.

 

thanks guys

 

The ITR one will work but don't forget too get a bigger trottle body later on because the ITR manifold is 62mm and the b16 t/b is 53 or something like that!!!
