What is the primary function of a blow off valve?

A blow off valve releases excess boost pressure from the turbocharger system when you lift off the accelerator. This prevents compressor surge, which can damage the turbo, and helps maintain turbocharger speed for quicker spool-up on subsequent acceleration.

What kind of sound can I expect from this Turbosmart Supersonic BOV?

The Supersonic BOV is known for producing a significant and distinct sound when releasing boost. It's often described as a sharp, noticeable 'whoosh' that is more pronounced than some other factory or aftermarket valves.

Does this blow off valve come with everything needed for installation?

While the Turbosmart Supersonic BOV is designed for easy installation, it's recommended to consult the manufacturer's instructions for any specific hardware or adapter requirements for your particular Subaru model. Some installations may benefit from additional components.

About this part

Product Details

This is the Turbosmart Supersonic Blow Off Valve, designed specifically for your 2002-2014 Subaru Impreza. If you're running a turbocharged Subaru, this part is a popular choice for managing boost pressure. It works by releasing excess pressure from the turbo system when you let off the throttle, preventing compressor surge and helping to keep your turbo spinning freely between shifts. This means more consistent boost delivery and a more responsive feel when you get back on the gas.

What sets the Supersonic apart is its design for high flow and a noticeable sound. It's a well-built unit that's straightforward to install and set up, making it a favorite for tuners and racers looking for improved performance and a unique auditory signature from their turbocharged Subaru. The black finish gives it a clean look under the hood.
