Forge BMW N54 Chargepipe with BOV (1M, 135i & 335i)
Suitable for the BMW E82 E88 135i & E90 E91 E92 E93 335i fitted with the N54 Twin Turbo engine. This alloy hard pipe fits to the throttle body and incorporates our high flow blow off valve. This valve, fresh from our R&D department, is the largest displacement valve that Forge have ever made! Featuring a 50mm (2”) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet!
The piston uses heat stabilised Viton o-rings and high-temperature grease to ensure a long life with minimal wear and very long service intervals.
Note: that due to the high flow (and low restriction) offered by the 50mm valve, they are very quiet in operation.
We recommend the option Blue Spring + 6.3mm Shim (-10 PSI) for most N54 application, unless you have measured your vacuum pressure reading and are producing much more or much less than than 10psi, this should be taken at normal operating temperature whilst the engine is idling with a pressure gauge for accuracy.
You can also add the optional 10mm Shim with your order, with this additional Forge 10mm Shim, you can switch between 10psi and 11psi depending on your requirement.

My OEM chargepipe had at the time cracked right on the throttle body (a common issue with these) I read the forums and reviews on this and sent it. We are now 8 months in 0 issues and looks and sounds the part, for anyone who has just got an N54 this should be at the top of your list to replace!
Ordered alot of items off ML now and every time its very fast delivery and always in perfect condition. Forge bov is a very suttle quiet sound but does the job perfectly for the people wanting to be discreet. If your wanting a louder blow off sound the hks is a better option. I own both and if going to a car show the hks goes on, if daily driving the forge goes on.
