This GFB BOV Kit is designed for the KIA Stinger, and features the quality and reliabilty customers have come to expect from GFB Blow Off Valves. This is a mixed valve kit, featuring one Mach 2 valve and one Respons valve that feed off a common plenum. Taking into consideration the KIA Stinger's lack of MAF, this kit constitutes a far more affordable alternative to installing two pricey Respons Valves, offering great performance at a fraction of the cost.
