Upgrade your Kia Stinger (2018–2023) with the ADD W1 Direct Bolt-On Blow Off Valve Kit, engineered to improve turbo performance, throttle response, and deliver an aggressive blow-off sound.

This direct bolt-on kit replaces the factory OEM diverter valve system and installs with no cutting, welding, or modifications required — perfect for maintaining factory specifications while upgrading performance.

The ADD W1 BOV is CNC-machined from high-quality aluminum for durability and precision. It is designed to work with both stock and tuned engines, making it ideal for daily driving or high-performance builds.

Key Benefits:

• Improves throttle response and turbo efficiency
• Releases excess boost pressure to protect turbo system
• Prevents compressor surge and reduces turbo lag
• Extends turbocharger and intercooler lifespan
• Direct bolt-on installation (no modification required)

Performance Function:

When running higher boost levels, pressure builds up in the intake system. The blow off valve releases excess compressed air when the throttle is closed, preventing compressor surge and protecting turbo components from damage.
