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.

GFB DV+ T9356 Turbo Bypass and Recirculation Valve Upgrade for BMW N55

Unlock sharper throttle feel and stronger boost retention on your N55-powered BMW with the GFB DV+ T9356. This performance upgrade replaces the weak OE internals with hard-wearing anodised billet aluminium and a precision brass piston while keeping the factory electronic control for rapid ECU response. The outcome is crisper acceleration, faster spool, cleaner gear changes and dependable sealing under load. Ideal for owners of 135i, M135i, M235i, 335i and 435i who want a direct bolt-on turbo bypass valve that delivers results without gimmicks.

We run DV+ on our own N55 builds and have installed it for many customers. Feedback is consistently positive. Expect better mid-range punch, smoother part-throttle, reduced lag and no unwanted flutter. If you are shopping for a BMW turbo recirc valve upgrade for remapped or stock cars, the DV+ is the proven choice that just works.
