GFB Respons TMS Blow-Off Valve Kit - Kia Stinger / Genesis G70 3.3T 2018-2023

The GFB Respons TMS kit is a direct bolt-on blow-off and diverter valve upgrade for the 3.3T twin-turbo V6 in the Kia Stinger and Genesis G70. It ships with one Respons TMS valve and one Mach 2 valve so you can mix venting styles, and the Respons uses GFB's adjustable venting bias to dial anywhere from fully recirculated and silent to a loud atmospheric vent. The TMS design recovers boost up to 30 percent faster on gearshifts and holds high boost without leaking, all without cutting or modifying the factory system.
