This GFB Hose Plug is used to block the plumb-back hose in a full atmosphere-venting application. It will suit any 30mm hose, and is included with GFB blow-off valves.
GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves. Factory diverter valves are commonly known to leak or fail, especially with age or higher boost levels. A GFB TMS will hold as much boost as you can throw at it, 24/7 - No frequent re-builds or replacement required
GFB's whistling trumpet gives off a unique high-pitch whistle sound on gearshift. It is a direct screw-on replacement for the standard trumpet found on most GFB valves, and is recommended for use where peak boost pressure is above 13psi.
The COBB XLE BPV is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking. Its unique design allows for extremely fast venting of boost when actuated. It is designed to operate in multiple venting modes and can be quickly reconfigured using simple hand tools. Innovative engineering and precision manufacturing result in a compact package able to fit in the confines of a tight engine bay.
