Get rid of the quiet and basic sound of your stock Focus' engine and let your turbocharged engine announce its presence with this blow-off valve. If you are looking for a way to make your Focus ST more exciting to drive, this is a simple and quick upgrade that will have you smiling with every shift.
Classic turbo woosh. The Kompact Shortie Dual Port BOV vents pressure to the atmosphere, making that classic sound that turbo cars are known for. This is a great way to make your Focus stand out from stock cars.
Exceptional construction. Turbosmart builds its BOV's with great quality. Unlike the plastic factory unit, this BOV features a billet aluminum housing and aluminum/brass internals that ensures it will offer years of performance. The mechanical operation means you do not have to worry about electronics failing over time.
Better performance. Upgrading to the Turbosmart blow-off valve will improve the response by keeping your turbo spooled. The blow-off valve also prevents compressor surge, which is hard on your turbo and bearings, leading to increased wear and tear.
Dual-port. Get the best of both worlds with the dual-port BOV. At low rpm's and normal driving conditions, excess pressure is vented back into the intake, like the factory system, allowing for quiet and comfortable operation. During spirited driving, the blow-off valve vents to the atmosphere for a more exciting and sporty sound.
