Fits: 2003–2006, 2008–2018 Porsche Cayenne aFe77-16411Programmers & TunersAutomobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels. The ETC system (Electronic Throttle Control) – also known as drive-by-wire – has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gear changes, overtaking, etc. The Sprint Booster aims to overcome this throttle response delay for ETC-equ ipped vehicles, providing crisp on-tap acceleration at the driver's disposal.aFe Sprint Boosters offer your ride an adrenaline kick! Designed for ETC systems, or drive-by-wire, these simple-to-install power modules plug into the OE connector located behind the accelerator pedal--no wires to cut. aFe Sprint Boosters deliver improved acceleration and reduce throttle response time. They will not affect your vehicle's electronic system and offer three settings for better drivability: factory (off), sport (green), and race (red). Raise the performance level of your ride with aFe Sprint Boosters.
