MotorVac 8 Ounce Fuel Cleaner - 400-0020. Fuel injection cleaner is designed to dissolve fuel contaminant deposits from your injectors and other areas of your fuel system. Carbon deposit buildup can cause poor fuel mileage, harder starts, and loss of power. If you notice you are getting less power from your vehicle, check out O'Reilly Auto parts.
The cleaning solution is safe for electrics so the injector can be imursed and cleaned over night. Any remaining crud will be ejected from the injector on startup once re-installed again. And a good injector cleaner will finish the job. This method is by no means as good as having them properly cleaned on a jet bench.

Since with direct injection it doesn't hit the intake valve so will not prevent the carbon buildup.
