Description

The ADD W1 Blow Off Valve Kit is designed to upgrade the performance and sound of your Kia Stinger (2018-2023). This direct bolt-on system replaces the factory diverter valve, enhancing turbo performance, throttle response, and delivering an aggressive blow-off sound. Installation is straightforward, requiring no cutting, welding, or modifications, making it ideal for maintaining factory specifications while boosting performance. It is compatible with both stock and tuned engines, suitable for daily driving or more demanding performance builds. The valve functions by releasing excess compressed air when the throttle is closed during higher boost conditions, thereby preventing compressor surge and protecting crucial turbo components from damage. Key benefits include improved throttle response and turbo efficiency, release of excess boost pressure, prevention of compressor surge and turbo lag, and an extended lifespan for the turbocharger and intercooler. The kit includes a vehicle-specific adapter or flange, hoses, fittings, bolts, an O-ring seal, a C-clip, and all necessary installation hardware.
