Enables Greater Boost. The stock blow-off valve (BOV) is adequate for the every day commuter car. But if you are planning on increasing the boost and power of your EcoBoost Mustang you are going to need a Turbosmart Kompact Shortie Blow Off Valve that can handle the extra pressure - up to 30psi.

Recirculating Blow Off Valve. Turbosmart designed their BOV to be a fully recirculating valve. This means all the excess pressure is routed back into the vehicle's intake. Providing quieter operation, this Blow Off Valve is ideal for those looking for more power without attracting unwanted attention.

Vacuum Activated. Unlike the factory Ford blow-off valve that is electronically controlled by the ECU, the Turbosmart Kompact Shortie Blow Off Valve is mechanically operated by vacuum for consistent manifold pressure that helps keep your turbo spooled for better throttle response.

Quality Construction. Constructed from aircraft grade aluminum alloy for durability and strength, this Turbosmart Kompact Shortie Blow Off Valve features a light-weight brass/aluminum two-piece piston, which is then perfectly matched with precision engineered springs allowing for razor sharp valve response.

Application. The Turbosmart Kompact Shortie Recirculating Blow Off Valve is designed for use on all 2015-2023 EcoBoost Mustang's equipped with the turbocharged 2.3L Inline 4-cylinder engine.

Technical Note. This Blow Off Valve is not legal for use in California or other states adopting California emission standards.
