Go Fast Bits TMS Blow-Off Valve (02-07 WRX & 04-12 STI)
This is Go Fast Bits' TMS Blow-Off Valve for the 2002 - 2007 Subaru WRX and 2004-2012 STi in BLACK.
TMS - Turbo Management System - GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves.
Factory diverter valves are 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.
- BETTER RESPONSE
- Through reduced turbo lag - The GFB TMS is designed specifically to minimize lag - tests show that it can return the engine to peak boost up to 30% faster than a factory diverter when shifting gears, while delivering up to 40% more transitional boost (see GFB brochure)
- BETTER DRIVEABILITY
- Smoother than stock. Factory diverters tend to operate fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.
- GET THE SOUND - OR NOT
- It's your choice! Want noise? GFB patented Respons succeeds where others have failed! By adjusting the venting ratio of atmosphere/recirc, you CAN achieve a sound WITHOUT throwing a CEL, running rich, stalling using more fuel or causing other problems commonly associated with atmo-venting valves.
