Why does it get clogged up?
Your vehicle's emissions lowering system is designed so that a proportion of the engine exhaust gases are diverted back into the intake manifold via the exhaust gas recycling valve (EGR) to aid reducing combustion temperatures.
This in turn reduces combustion temperatures and increasing poisonous NOx gases that pollute the environment. A downside to using EGR valves is that some of the carbon, resins and oil vapor residues that are present in the exhaust gases coat the inside of the intake manifold, forming carbon build up.
Over time, the build up of carbon restricts air flow, restricting engine performance and lowering fuel efficiency, which activates the restricted performance mode of your vehicle and illuminates the engine management warning light.
How do we clean the air intake?
Our carbon cleaning tool injects a strong solution directly into the vehicle's air intake system, removing contamination from the inlet manifold and inlet valves. By doing this, we no longer have to dismantle the vehicle.
This treatment has also been effective in cleaning:
