The Carbon Cleaning ?
Prevents maintenance on engine problems

Preventive engine cleaning enables you to restore engine parts rather than replacing them, thereby saving vehicle owners on costly parts, such as a new turbocharger ($ 1.350 – 3.100), catalytic converter ($ 600 – 2.000), DPF ($ 600 – 2.000) or EGR valve ($ 370 – 500).

These problems result mainly from poor combustion, which stifles the engine.

So before replacing your engine parts, try Carbon Cleaning. A dirty engine as the result of carbon deposits is the new threat to vehicle performance.
