Some of the first to arrive in the USA are the bolt-on kits for the popular (GDB) WRX / STI and (CT9A) Evo8/9 turbo applications. Both of these kits include all the proper adapters and hardware to install a GReddy FV Blow off Valve and allow for recirculation of the blow off back into the air intake track. (But it can also be configured to blow open to atmosphere.)
Applications for (R35) GT-R, (S14/15) Silvia, (CZ4A) EvoX, (GRB) WRX/STI, (FD3S) RX-7 and (JZA80) Supra coming soon... (Pre-Orders are now being accepted.)
