Respons TMS Direct Fit Blow Off Valve
On the surface, it may look like just another dual-port blow-off valve, but the Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets. For example, using GFB’s TMS (Turbo Management System) principle, tests show that the Respons can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.
Features
- Adjust the volume of your blow-off sound
- Up to 30% faster boost recovery on gearshift
- Get the blow off sound without the hassles - even on sensitive MAF-based systems
- Hold unlimited boost pressure
- Direct Bolt-On Installation
Applications
- 2015-2019 Subaru WRX FA20
- 2014-2018 Subaru Forester XT FA20
What's In The Box?
- (1) TMS Respons BOV
Warranty
