ISIS Intake Manifold - Polished - Nissan

its the same product as the ebay shit! you just need to port match it, and try to smooth out the inside of it. shitty casting!
 
I ran one on my s13 before i sold it. I lost a lot of tourqe, unless you're running a decent size turbo then its a waste of money, It is rather baller though :rolleyes:
