BOV RacePort EM Plumback GenV Sleeper

The BOV RacePort EM Plumback GenV Sleeper from TURBOSMART USA is a premium blow-off valve designed for turbocharged and supercharged vehicles seeking silent, efficient boost relief without audible venting. This advanced plumback-style BOV is engineered for street and track applications where surge suppression and intake silence matter equally—making it ideal for daily drivers, weekend warriors, and serious modifiers who refuse compromise between performance and stealth.

The RacePort EM features electromagnetic actuation technology that delivers precise, load-reactive boost control by venting excess pressure back into the intake manifold rather than atmosphere, eliminating the telltale turbo whistle while maintaining crisp throttle response and eliminating compressor surge. Its Gen V design refines valve flow geometry and seal integrity, minimizing flutter and chatter across the entire boost range—critical for turbocharged engine longevity and consistent drivability. The sleeper configuration integrates seamlessly with stock or modified intake systems, reducing installation complexity while maximizing reliability in high-heat engine bay environments.

This valve suits owners of turbocharged four-cylinder, V6, and V8 platforms seeking refined boost management without visual modifications—particularly valuable on street-legal track cars and performance commuters where a factory appearance is preferred. Installation typically requires integration with intake plumbing and boost control solenoid harness; most experienced DIY builders complete fitting within 2–3 hours with basic hand tools. The compact 5.5 x 5.5 x 6.75-inch form factor and lightweight 1.6-pound design ensure clearance in tight engine bays while maintaining TURBOSMART's legendary durability across countless boost cycles.
