Description
Enhance your BMW’s turbo performance and reliability with the Turbosmart BMW B58 Gen 3 Plumb Back Kompact EM Blow-Off Valve (BOV) – part number turTS-0223-1248. This premium component belongs to Turbosmart’s award-winning Kompact EM Series, the world’s first plug-and-play upgraded blow-off valve designed to directly replace your factory diverter valve—no adaptors, hoses, or complex installation required.
The Kompact EM Series incorporates motorsport-proven billet valve technology combined with Turbosmart’s proprietary onboard solenoid system and integrated internal pressure control channels. This unique design ensures full OEM electronic integration and control, delivering improved boost response and stability under all driving conditions.
Unlike factory plastic valves that often fail under high boost, the Turbosmart Kompact EM BOV uses Boost-Balance Valve Technology to provide superior sealing as boost pressure increases. The positive-seal O-ring on the piston face ensures leak-free operation, while the CNC-machined billet aluminum construction guarantees long-term durability even in demanding environments.
This Plumb Back version of the Kompact EM BOV recirculates air back into the intake system, maintaining quiet operation and OEM-style drivability — perfect for enthusiasts seeking reliable performance without the attention of vent-to-atmosphere noise.
