MotorVac CarbonClean MV4 Intake System Cleaning Detergent 12 x 8 oz Fuel injectors, intake valves and combustion chambers are adversely affected by the build up of contaminants. These contaminants can affect drivability and fuel economy. MotorVac CarbonClean detergents loosen and dissolve the carbon, gum and varnish that build up throughout an engine's fuel system. CarbonClean detergents use a highly effective proprietary formula to restore the performance of the vehicle's fuel system without the use of harmful alcohols such as methanol and hexanol which can dry the seals in a fuel system. CarbonClean detergents will not damage the engine components and can be used with confidence. MV4 incorporates a foaming action to decarbonize the air intake, plenum, throttle body, intake runners and intake valves and is applied using the ICS kit or the S-Tool Canister. 12 x 8oz (236ml) Bottles
