Untreated carbon deposits will cause problems for vehicle owners. Issues like power loss, decreased mileage, failed emissions, hard starting, rough idling, and hesitation can absolutely shorten the life of an engine. Today’s Gasoline Direct Injection (GDI) technology creates even more deposits in harder to reach places. When combustion chamber deposits exist, the combustion chamber size is reduced, creating an environment for engine knock, engine run-on and the need for higher octane fuels.


Throttle Muscle is proud to present SynFog, the newest generation of fuel system cleaner, and the most concentrated fuel system cleaner in our line. Cleans and removes performance-robbing deposits from intake manifolds, air intake systems, ports, valves, and combustion chamber in all gasoline engines. SynFog is a fully synthetic cleaner with a natural fogging action that removes intake valve deposits by way of the air/fuel/SynFog mixture. By controlling or reducing intake valve deposits, engines run smoother and vehicle life is maximized.
