Here, you are looking at the Turbo XS Recirculating Blow Off Valve Type XS. This is a direct replacement for the factory blow-off valve that has been designed to respond faster while holding more boost to improve the performance.
Direct replacement for 2015 models
Designed to upgrade your factory blow-off valve but to recirculate the vented boost back into the intake
The modular design of the XS platform will allow you the option to change both the inlet and the outlet with the Turbo XS trumpet (sold separately) to make it vented to the atmosphere
Responds quicker and holds more boost for those with modifications that increase the power output
