Product Details

Forge Motorsport adds another replacement valve application to our already extensive vehicle specific and universal valve lineup. 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 own 007P piston-based design we have 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.

The valves are fully tunable for both boost holding capacity and response by way of proprietary interchangeable springs and shims (washers to marginally adjust pre-load). By utilizing this method of valve tuning with multiple custom spring rates the valves will retain the maximum range of piston travel and flow volume regardless of which spring rate is used.

Though these types of valves may hold high boost levels under load they will actually suffer from limited flow volume at throttle lift when the valve vents. The hoses included in the kit are a custom made multi-layer fabric reinforced flexible silicone hose that are designed to allow compatibility with the stock airbox and charge piping setup without any permanent modification being required to adapt our replacement valves. Even the included hose clamps are overkill. They are specifically designed for use with silicone hoses utilizing a beveled band edge and a pressed in drive mechanism rather than perforated.

*Spring Rate is 9-15psi*
