Blow Off Valve Kit for BMW 135/235 Dump Recirculation Diverter, Aluminum No Noise N20 2.0 Turbo
Upgrade your BMW’s turbo efficiency with the BMW 135/235 Dump Recirculation Diverter Blow Off Valve Kit. This NO NOISE version is a complete bolt-on, piston-style BOV engineered for the N20 2.0 turbo engines found in F20/F21/F22/F23 and related chassis. Crafted from CNC billet aluminum and sealed with high-temp Viton O-rings, it replaces the factory diaphragm to prevent boost leaks caused by diaphragm rupture or piston wear. The result is faster throttle response, consistent boost control, and a more precise venting action—without the audible chatter of typical aftermarket valves or triggering a check engine light. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability.
Benefits & Tips
- Enhanced throttle response with faster piston opening and no boost leaks, improving acceleration feel across RPM range.
- No-check-engine-light operation thanks to the piston design and calibrated venting, keeping your BMW’s ECU happy during spirited driving.
- Serviceable design means components like the O-rings and piston can be inspected or replaced, extending valve life without replacing the entire unit.
