The ADD W1 Blow Off Valve Kit is designed for enthusiasts looking to improve turbocharger performance, enhance throttle response, and add the signature blow-off sound to their Infiniti Q50 or Q60 3.0T.

Built with premium materials and engineered for direct OEM-style fitment, this BOV kit delivers reliable performance for both daily driving and modified turbocharged setups.

The ADD W1 Direct Bolt-On Blow Off Valve Kit is designed as a direct replacement for the factory OEM diverter valve system on the Infiniti Q50 and Q60 3.0T VR30DDTT platform.

This complete bolt-on BOV kit is compatible with both stock and aftermarket tuned vehicles and includes all required installation hardware, including vehicle-specific adapters, hoses, fittings, bolts, O-ring seals, and retaining clips. No welding, cutting, or permanent modifications are required.

Engineered for enthusiasts who want improved turbo response, enhanced throttle performance, and aggressive blow-off sound while maintaining OEM-style fitment and reliability.

The ADD W1 Blow Off Valve is CNC machined from high-quality aluminum for maximum durability and performance under high boost conditions. The valve is designed to safely release excess boost pressure from the intake and intercooler system when the throttle is released.

Under high boost applications, excess pressure can place stress on the turbocharger compressor wheel and intake piping. Installing a high-performance blow off valve helps relieve compressed air pressure, reduce compressor surge, protect intercooler piping, and improve turbocharger longevity while minimizing turbo lag.

FEATURES

• Direct bolt-on replacement for OEM diverter valves
• Compatible with stock and tuned engines
• CNC-machined billet aluminum blow off valves
• Improves throttle response and turbo performance
• Helps reduce compressor surge and turbo lag
• No welding or permanent modifications required
• Includes complete installation hardware
• Engineered for high-boost turbocharged applications

Blow Off Valve Standard vs Blow Off Valve Pro

The ADD W1 Blow Off Valve Standard and Blow Off Valve Pro models are both precision CNC-machined aluminum units engineered for responsive turbo performance and durability.

The Blow Off Valve Standard is ideal for stock or lightly modified turbocharged engines and offers reliable performance at an affordable price point.

The Blow Off Valve Pro is designed for higher boost applications, aftermarket tuned setups, and performance-focused vehicles requiring improved response and a more aggressive blow-off sound.

Benefits of the Blow Off Valve Pro include:

• Louder and sharper blow-off sound
• Faster valve response under low boost conditions
• Improved airflow performance
• Better suited for tuned and high-performance applications
• Enhanced durability for higher boost pressure setups

Which Blow Off Valve Should You Choose?

Choose the Blow Off Valve Standard for daily driving, stock turbo setups, and mild performance upgrades.

Choose the Blow Off Valve Pro if your vehicle is tuned, running higher boost levels, or if you want a more aggressive sound and faster turbo response.

Both versions are built from premium CNC-machined aluminum and engineered to deliver reliable performance, improved turbo efficiency, and long-term durability.
