Turbo XS Mazdaspeed3/Mazdaspeed6 RBV BOV

This Turbo XS RBV Blow Off Valve is made for the 2007-2013 Mazda 3 and the 2006-2007 Mazda 6. It's designed to help manage the boost pressure created by your turbocharger, releasing excess pressure when you lift off the throttle. This helps protect your turbo from damage and can improve throttle response.

The RBV, or Recirculating Bypass Valve, is a well-built unit from Turbo XS. It recirculates the excess boost pressure back into the intake system, which is generally quieter than a vent-to-atmosphere valve and often required for emissions compliance in some areas. This design helps maintain smooth idling and prevents the engine from running too rich after a gear change. The valve itself is constructed for durability, ensuring it can handle the pressures and temperatures found in the engine bay.

When installing this valve, you'll want to ensure you have the correct tools for accessing the turbo plumbing. It's a direct replacement for the factory bypass valve, making the installation straightforward for someone familiar with working on turbocharged Mazdas. Keep in mind that this part is not CARB approved and cannot be shipped to California.
