Transform your vehicle's performance with the Sprint Booster, a state-of-the-art electronic device designed to deliver swift and instantaneous acceleration, effectively eliminating any delays. Featuring a convenient dash-mounted selectable switch, you can effortlessly switch between stock, moderate, and aggressive acceleration modes by simply pressing an LED button.

In the era of modern automobiles, traditional throttle cables have largely been replaced by electronic control modules. These modules translate pedal pressure into electronic signals, allowing the vehicle's computer to precisely control acceleration. However, the Electronic Throttle Cable (ETC), also known as the "Drive by Wire" system, often suffers from delayed response and subdued acceleration, particularly during uphill starts, rapid gear changes, or when passing other vehicles.

Installing the Sprint Booster is a straightforward process – simply plug it in between your accelerator pedal module and the harness. The difference is instantly noticeable the moment you press the throttle. Should you ever wish to revert to your stock setup, removal is equally uncomplicated.

Rest easy with the protection of a money-back guarantee that allows you to experience the performance difference without any risk.

New to V3: 36 Acceleration Programs, Valet Mode, Pedal Lock Mode**

This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.

When BMW began using the "Drive-by-wire" throttle system in 2001, a lot of people cringed. The Drive-by-wire system uses electronics to replace the mechanical cable throttle of the past. This means the electronics between the accelerator pedal and motorized throttle must interpret what your right foot does, and ultimately decides how the engine will respond. Although advanced in it's technology and engineering, many of us agree that the Drive-by-Wire equipped BMWs feel unresponsive and lack the crisp, sharp throttle response that older BMWs had with a traditional throttle cable. That's where the Sprint Booster comes in.
