This is a direct bolt-on replacement for the factory bypass valve and was designed to the be THE BEST blow off valve on the market. Using a large 44mm piston and Viton O-rings to withstand the high air charge pressures and outlet temperatures from your...

The DVX range covers vehicles that can't fit or use valves like the Respons or Deceptor Pro II, and each version in the range is designed specifically for its application, ensuring the best fit and performance.Installation InstructionsThis Part...

VTA BOVs vent to atmosphere to make the signature turbo blow-off sound, where the DV+ recirculates the air to keep it quiet. Each valve in the VTA range is designed specifically for the applications we list them for, ensuring the best fit and performance...

The intake is acoustically tuned to surpress the fluttering sound of compressor surge, it does not eliminate the effect of pressure pulses- that is what diverter and Blow off valves were originally designed to doInstallation InstructionsThis Part...

Furthermore, these benefits won't cost you the Earth! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer's "solutions"), the DV+ keeps what works, and replaces what doesn't. It retains the factory solenoid...
