This RS4 Gets A Carbon Cleaning
With 92k miles on the odometer, this B7 Audi RS4 Cabriolet was ready for some attention. These direct port engines suffer from carbon buildup due to the lack of fuel to lubricate the intake path as the air is drawn into the motor. The linkage arms on the intake manifold that actuate the intake flaps are made of plastic and known to break. Excelerate Performance replaced these with Billet Upgraded units from 034 Motorsport to avoid this issue down the road.
