Turbosmart BLOW OFF BMW 135I 335I Z4 Kompact Plumb Back Kit TS-0203-1250

The BOV Kompact Plumb Back valve transfers all excess pressure back to the intake. Ideal for people looking for performance without generating additional venting air noise through the valve. Standard valves made of plastic, as opposed to the very strong machined aluminum Kompact construction. In standard valves, plastic becomes brittle with age and can crack, causing severe blow-bys. This prevents the turbo from reaching its full capacity, depriving you of performance. With an anodized aluminum body and a lightweight alloy piston, the Kompact offers extreme durability, excellent response and excellent pressure-holding capability in a small package. Fits: BMW 135i (3.0 N54) BMW 335i (3.0 N54) BMW Z4 (3.0 N54) Includes: Two valves, screws and mounting bands, springs 0.5 BarFull recirculating BOV. The Plumb Back system recirculates all excess pressure back into the intake system. Great for enthusiasts not wanting to be noticed but wanting the performance and reliability benefits of a quality BOV The standard blow-off valves on these cars are made of plastic, unlike the highly durable machined billet construction of the Kompact. The standard valves are often not up to the task of eliminating damaging compressor surge, and as the cars age, the plastic becomes brittle and can crack, causing severe boost leaks. This prevents the turbo from reaching its full potential, robbing you of performance. & Nbsp
