Overview

The ADD W1 Blow Off Valve Kit is a direct bolt-on upgrade for the Kia Stinger, engineered to enhance turbo performance and throttle response. It replaces the factory OEM diverter valve system without requiring any cutting or welding.

It is compatible with both stock and tuned engines, suitable for daily driving or high-performance applications. The kit helps protect the turbo system by releasing excess boost pressure, preventing compressor surge, reducing turbo lag, and extending the lifespan of the turbocharger and intercooler.
