Boost the output of your Audi A4 with our 02 Performance Power Boosters.  The 02 PPB will install on the exhaust side O2 sensors and provide a great boost in power and efficiency.  These units have a simple two wire installation and come complete with instructions.  Once installed, the unit will optimize the readings from the o2 sensor(s) to provide the optimum settings for your engine.  By doing so, it will add power and give you much better throttle response.  You will need a 02 Performance Power Booster for each 02 sensor on the exhaust side.
