Fuel Injector Cleaner
When carbon deposits build up on fuel injectors, intake valves and ports, it can cause engines to hesitate, surge or lose power. It can also have a noticeable effect on fuel economy. Gumout® Fuel Injector Cleaner removes carbon deposits from these key engine parts to maximize engine performance and fuel economy.
