Turbosmart Kompact BOV Blow Off Valve Shortie Dual Port 2631143 DeFacto. A fixed 50 50 vented valve, the Turbosmart Shortie Kompact Dual Port valves have been specifically designed to suit BorgWarner EFR and KKK turbos. They also fit the popular Ford Ecoboost engines. Unlike the standard, plastic valves that use un reinforced diaphragms and are known to crack under increased boost, the new BW KKK Ecoboost Kompact valves use O Ring sealed piston which, coupled with their billet aluminium construction give them over 30PSI boost handling capability. Designed as a bolt on replacement of the factory valve on all BorgWarner EFR, KKK and most Ecoboost turbos, the Kompact Shortie Dual Port provides better boost response and greater boost handling capability. Included with each Kompact Shortie kit is: Model specific valve, Straight and Banjo Nipples, and Mounting screws.
