How to Clean Sonicator Fuel Injectors
Sonicators are in-line fuel mixing devices that are sometimes installed as an extra part to fuel injectors. Fuel-injected engines are in nearly every car on the road today due to their fuel efficiency and ease of tuning. The Sonicator fuel injector will correctly mix the fuel that comes from the fuel rail and then inject it into the combustion chamber of your vehicle. Due to the impurities present in any fuel, the Sonicator fuel injectors will sometimes get clogged and require cleaning. There are two methods of cleaning Sonicator fuel injectors: in car cleaning and out of car cleaning.

Tips & Warnings
If more thorough cleaning is required, visit a local auto repair shop and request an "acid cleaning" in which the injectors will be scoured with acid to clean out any impurities.
