Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Suitable for the BMW 335 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.
