CRC Industries Intake Valve Cleaner - 11 Oz

Carbon buildup on the backs of intake valves is the chronic issue with gasoline direct injection engines, and CRC built the GDI IVD cleaner specifically to address it. Because GDI injectors spray fuel directly into the combustion chamber instead of over the intake valve, there is no fuel wash to keep the valve clean. Over time, baked-on carbon deposits accumulate and cause rough idle, reduced power, and poor fuel economy.

CRC's 05319 formula delivers what they describe as the highest concentration of PEA (Polyether Amine) detergency available in an aerosol intake cleaner. You introduce it through the air intake system while the engine is running, and CRC's advanced Cozol technology works directly on the deposits. Their testing shows the cleaner removes up to 46 percent of intake valve carbon buildup in one hour of treatment. Beyond GDI engines, it also works on standard port fuel injection and turbocharged setups where carbon accumulates on the intake side.

This 11-ounce aerosol can is a maintenance item worth keeping on hand if your vehicle has a GDI engine. Regular treatment can help maintain throttle response and idle quality between major services.
