Automobiles 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-equipped vehicles, providing crisp on-tap acceleration at the driver's disposal.This Part Fits: Year Make Model Submodel 2006-2013 Audi A3 Base 2010-2013 Audi A3 TDI 2008-2014 Audi A4 Base 2008-2009 Audi A4 Cabriolet 2015-2016 Audi A4 Premium 2015-2016 Audi A4 Premium Plus 2015 Audi A4 Prestige 2008-2012 Audi A4 Quattro Avant 2008-2014 Audi A4 Quattro Base 2008-2009 Audi A4 Quattro Cabriolet 2015-2016 Audi A4
