Please refer to chart below for the correct model to suit your vehicle
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 ai vents from each of the two outlets
Why is this so important? Two key reasons:
- Adjust how loud the bloww-pff sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it anywhere in between to suit your preference
- Get a blow-off sound without causing stalling, backfiring or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF)
The Respons isnt just a noise-maker. It also:
- Offers better throttle response
- Faster boost recovery on gearshift
- Unlimited boost-holding
For example, using GFB's TMS (Turbo Management System) principle, tests show that the Respons can return engine to peak boost up to 30% faster than a factory diverter valve when shifting gears
