Description

The Go Fast Bits T9201 Hybrid Dual Outlet Valve is a blow-off/diverter valve that celebrates the 20th anniversary of its world-first dual outlet design. Originally invented to prevent stalling and backfiring on MAF sensor cars, it features staged venting ports, allowing the recirc port to open before the atmosphere port. This design provides the signature blow-off sound while mitigating issues common with atmosphere-venting valves.
