Turbosmart Kompact Dual Port Kit for Select BMW 2007-2020 (3.0L) TS-0203-1050

Fits select 2007-2020 BMW 1 Series M, 135i, 335i, 535i, 740i, X6, and Z4 (3.0L).

The Turbosmart Kompact Dual Port Kit is a precision-engineered performance upgrade designed to replace the failure-prone factory plastic diverter and bypass valves. While OEM valves utilize plastic housings and rubber diaphragms that can leak or perish under increased boost pressures, the Kompact series is CNC-machined from motorsport-proven billet aluminum for maximum durability and pressure handling.

This kit features Turbosmart’s proprietary boost-balance system, ensuring the valve remains closed under high boost while providing rapid response when venting. The 28mm high-flow piston utilizes high-temperature O-rings for a positive seal, making it a direct-swap solution for vehicles running factory or increased boost levels. The Dual Port design offers a split between recirculating air and venting to the atmosphere for a distinct mechanical sound without compromising drivability.
