The world’s first truly plug-and-play diverter-valve upgrade for the B58 Gen 3. Billet construction with Turbosmart’s Boost-Balance valve design – the more boost you run, the harder it seals. Dual Port vents partly to atmosphere for an audible flutter while keeping the OE drivetrain logic intact. No adaptors, no hoses, no tune required.
