To improve fuel injection performance, Mazda has tested and approved a highly effective FUEL INJECTOR
CLEANER. The kit and cleaner is recommended for all Mazda fuel injection systems. Mazda's Fuel Injector
Cleaner uses a chemical "reducing agent" rather than the common solvent used in the typical aftermarket
cleaners. As a result, in tests against aftermarket competitors, Mazda's cleaner outperformed all others and
was the only one to restore the fuel injector's flow rate to the original factory specifications.
Dirty fuel injectors are an increasing common problem. Many cases are due to gasoline deposits such as
gum, resin and sulfur. These deposits can cause stalling, difficult starting, rough idle and diminished power.
M azda's Fuel Injector Cleaner and Fuel Injection Tool Kit are available through the Parts Department. A lso
available is a Fuel Injector Service Brochure that is free o f charge from Helm, Inc. (1-800-782-4356). This
brochure outlines to your customer the importance and advantages o f a clean fuel injection system. Refer
to the following part numbers when ordering:

fuel injectors should be cleaned every 15,000 miles.
