Zawór blow off BOV Turbosmart TS-0203-1252 Kompact Shortie Plumb Back Mini Cooper S R56 R57 Clubman R55 - TS-0203-1252 - Turbosmart's Kompact EVR06 blow-off valves offer Mini owners the benefits of an aftermarket blow-off valve with the ease of a direct OEM replacement, offering improved boost response, better valve performance and race-proven durability. These new valves fit the 2006-2013 Mini Cooper S, and the 2010-2013 Mini Cooper JCW. Turbosmart's Kompact EVR06 is a high performance replacement for the Mini's standard plastic blow-off valve. Standard plastic bypass valves like those fitted to the Cooper S from the factory struggle to withstand increased boost pressures, and their plastic construction fatigues with the heat of the turbo and eventually crack. The Plumb Back is a 100% recirculating valve, for quieter operation and stealthy performance. The Kompact's billet construction and precision-matched piston ensures excellent boost-holding ability, combined with fast response and unsurpassed durability. The Kompact kit for the Mini includes a Boost Reference Adapter, which connects to the vehicle's MAP sensor to obtain a reliable manifold pressure reference, avoiding any destructive methods such as tapping into the manifold.
