BMC CDA Induction Kit for the Audi A4
The BMC Carbon Dynamic Airbox induction kit is made up of a carbon fibre airbox containing a unique filtering element.
The carbon fibre airbox acts as a heatshield to keep the heat out so that the induction kit performs at its highest peak at all times.
The kit also contains a flexible aluminium tube, which you direct to a frontal air intake on your car to enable constant air flow through the induction kit, into the engine.
Fresh air is channeled in to the engine through the filter and air flow deflector with minimum loss of power. By increasing the airflow at a speed and capacity greater than your standard airbox, the engine performance and torque are increased.
The induction kit simply replaces your standard air box so the kit is very easy to fit and comes complete with all fittings needed.
