The BG air intake system cleaner is a very effective way of removing carbon deposits from the intake system. Intakes manifolds will gum up with a combination of fuel vapors and PCV gases leaving a layer of deposits on everything. This layer can disturb the air flow in the intake as well as hinder correct operation of sensors and mechanical devices in the intake. It can put a layer of deposits on the air intake temperature sensor wire effectively insulating it from current intake temps sending false info to the ECU. It can build up behind the throttle plate requiring the throttle plate to increase opening percentage to achieve the same amount of airflow at idle. These are both very common in the 1.8T motor used by VW and Audi. Both of these issues can lead to poor driveability and poor fuel economy. When performing this service the technician has to be very mindful of the simple fact that you are introducing 22oz of fluid into a running engine and being mindful and logical will be your key to success.
BG Air Intake System Cleaner, Part No. 206
The correct balance of fuel and air entering the combustion chamber is crucial to engine
performance.
The air throttle body assembly controls the air flow into the intake ports where the air
mixes with atomized fuel and swirls into the combustion chamber. Heavy deposits build
up on the back side of the throttle plate, around and behind the plate and in the idle air
control.
BG Air Intake System Cleaner is an extremely effective solvent/degreaser formulation
that quickly removes sticky, heavy deposits which accumulate in the air throttle body
assemblies and plenums of modern, multi-port fuel injected engines. Cleanup reduces
harmful exhaust emissions and restores engine performance. Catalytic converter and
oxygen sensor safe.
