The Kompact Dual Port blow-off valve is a direct replacement for the stock bypass valve on the Mercedes A45 AMG. Standard valves crack with age and heat cycling, and rely on rubber diaphragms which perish. 

Kompact Dual Port blow-off valves are also designed to handle increased boost levels. Turbosmart's Kompact offers big blow-off valve performance in a small package. Its billet aluminium construction provides strength, while the precision-machined lightweight piston gives excellent valve response and sealing without relying on rubber diaphragms or O-rings, so it's far more durable, and guards against compressor surge even when the boost is turned up

The Kompact Dual Port features a 50-50 split operation between recirculating and vent-to-atmosphere. One recirc Port keeps the car's ECU happy, while one vent-to-atmosphere Port gives the classic Turbosmart blow-off valve sound we know and love.

These new Kompact Dual Ports offer an alternative to the existing Kompact Plumb Backs for the below cars, for owners who want the sound of a Dual Port BOV, but do not require the heavier-duty performance of the larger and higher priced Type 5.

The Kompact is suited to owners of otherwise stock or mildly modified vehicles, seeking the improved performance of an Turbosmart BOV with that classic vent-to-atmosphere sound.

The existing Kompact Plumb Back for these applications is ideal for those who prefer the quieter operation of a recirculating BOV, while the Type 5 is ideal for more highly modified cars running increased boost levels.
