Turbocharger Blow Off Valve

A blow off valve for the Mercedes 2.0L 4 cylinder is a great upgrade to improve your vehicle's performance and get that incredible turbo whoosh sound from your engine. The Agency Power blow off valve spacer has been engineered to fit between the turbocharger and the factory valve that releases pressure, also known as a "Priority Valve". In a typical turbo configuration, the turbocharger pressure is recirculated which can cause harmful compressor surge or slow down the spooling of the turbo. Changing a blow off valve from recirculating to atmosphere venting has been a common practice in turbocharger systems. Because of the design of the Mercedes turbocharged engines, there is no adverse affects from making this upgrade. Made from billet 6061 aluminum which is precision CNC machined here in the USA, the new valve features 4 holes on either side that vent the turbocharger pressure to atmosphere between gear changes or when you let off the throttle. Anodized in black for a OEM look, the blow off valve spacer features a laser engraved Agency Power logo and two stylish machined lines around the valve body. The valve includes required o-rings for a air tight seal. Because there are no moving parts, this product does require any maintenance or adjustments.
