The GFB Hybrid TMS is a dual-outlet valve that vents partly to atmosphere and partly back into the intake. By staging the two outlets, it recirculates most of the air at low valve lift for clean idle and driveability, then exposes more of the atmosphere-venting port as the car is driven harder for an audible blow-off sound. It can be configured for full recirculating, 50/50, or full atmosphere operation using the plugs provided. This valve suits 1997-2005 VW Golf GTI 1.8T.
