Show original supplier description
The ADD W1 Direct Bolt-On Blow Off Valve Kit is engineered to upgrade the Kia Stinger models from 2018-2023. This kit directly replaces the factory diverter valve system, offering improved turbo performance, enhanced throttle response, and an aggressive blow-off sound without requiring any cutting, welding, or modifications. The primary function of this blow-off valve is to release excess compressed air when the throttle is closed during high boost conditions. This action prevents compressor surge, reduces turbo lag, and protects critical turbo components and the intercooler from potential damage, thereby extending their lifespan. Installation is straightforward as a direct bolt-on, with the kit including a vehicle-specific adapter or flange, all necessary hoses, fittings, bolts, O-ring seal, C-clip, and complete installation hardware. It is designed to work with various engine configurations, including the 2.0T, 2.5T (2021-Up), and 3.3T models, with specific dual BOV kits for the 3.3T and single kits for the 2.0T. Available color options include Black, Red, and BLACK/RED.
