FBM Billet 72mm Nissan R35 GTR
FBM Billet throttle body was designed to increase flow and eliminate the bottle neck restriction when going to larger intercooler piping and bigger turbos. Full Blown has found the OEM throttle bodies to be quite restrictive on higher power setups.
Modeled after the OEM design, this design was able to increase bore diameter while keeping a sleek design. FBM also opted for a brass throttle plate for its strength compared to aluminum.
