Developed specifically for BMW’s N54 twin turbo motor, as found in the BMW 135,335 and 535 models, Forge Motorsport adds another replacement valve application . While virtually identical in operation to the Bosch style valves as used from the factory on many other turbocharged applications, primarily Volkswagen and Audi, BMW has utilized a very different type of valve connection mechanism that makes their product and our replacement components very unique. Starting with the world’s best selling direct replacement Bosch style valve, our piston-based design, has been revised virtually every single component of the valve body, (except the internal piston), in order to retain BMW’s unique connection mechanism yet offer improved functionality in every other possible way.
