Upgrade your Genesis G70 / G80 (2018+) with the ADD W1 Direct Bolt-On Blow Off Valve Kit, designed 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 allows installation 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 works 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.
Vehicle Fitment:
• 2018–2022 Genesis G70 3.3T (Includes Two ADD W1 BOVs + adapters)
• 2018–2022 Genesis G70 2.0T (Includes One ADD W1 BOV + adapter)
Includes:
• Vehicle-specific adapter / flange
• Hoses, fittings, bolts, O-ring seal, C-clip
• Complete installation hardware
Blow Off Valve VS. Blow Off Valve Pro
The main difference between the Blow off Valve Stander and the Blow off Valve Pro is that the Stander is designed for use with a smaller engine, while the Pro is designed for use with a larger engine.
The standard is the more Affordable of the two. The pro is more durable to handle higher boost and an aftermarket tuned engine with more powerful sound, better response even at a low boost.
Blow Off valve Pro, will provide a powerful response even at low boost situations and produce a much more powerful sound than a Stander blow off valve.
Which one should I get?
Blow Off Valve Stander and Blow Off Valve Pro are both high-quality aluminum die-cast bodies with Blow Off valves that use CNC machining to optimize clearance and bring responsiveness.
However, the great benefit of choosing the Blow Off Valve Pro model is its ability to produce a louder and sharper open sound, which is particularly advantageous for a high-performance engine. The sound it has is more powerful and generates better response even at a low boost, making it an excellent choice for those who want to make a statement with their vehicle.
