Description

The Go Fast Bits 5920 is an atmosphere conversion kit designed to convert a Mach 2 blow-off valve from recirculating to atmosphere venting. The kit includes a trumpet, a firmer spring, and a 20mm hose plug. It is suitable for the T9120 and is intended to help ensure the piston stays closed at idle to prevent stalling or backfiring.
