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 Plumb Back provides better boost response and more excellent boost handling capability.
