Maintec blowoff valve adapter will convert your 3.3L Kia Stinger's dual factory re-circulation valve into a blowoff valve setup, giving it the iconic turbo sound! CNC machined in-house at Maintec out of aerospace grade 6061 billet aluminum, the this adapter plate is an easy bolt-on part that requires no modification or tuning. On high boost applications, this also helps to prevent turbo surge by allowing the pressure to vent to the atmosphere. Includes a genuine HKS 71008-AK004 blowoff valve.
