Carbon removal on all FSI and TFSI is a subject which needs little or no introduction, due to TFSI/FSI engine design aimed at lowering harmful emissions and increasing power and torque the injector no longer sits in the manifold which provides precious lubricating and cleaning properties to the inlet valves.

The injectors are now located directly in the combustion chamber and aimed directly at the crowned piston creating a unique injector spray pattern and flame spread within the cylinder, a bi product of which is heavy carbon build up on and around the inlet valves which ultimately kills power from the engine by reducing the capacity to burn fuel and air !

Other symptoms include poor performance, mis fire, lumpy idle speed, lethargic engine response, poor fuel consumption, engine MIL lamp, restricted performance and generally just really bad for the breath-ability of your engine and needs getting rid of fast !!

ADS have tried and tested many methods of cleaning the carbon from the inlet valves and have found by far the best way is to use polymer beads which are blasted at high velocity, this method is both incredibly clean and efficient.
