DirtyInjectors.com provides
professional ultrasonic fuel injector cleaning and flow testing services. Our state of the art testing
equipment allows us to visually check injectors for leaks, faulty spray patterns and confirm flow rates.
To strengthen our proven testing and diagnostic procedures, and to confirm proper functionality at all
levels of operation, we check the injectors electronically for current draw and pulse them from 600 to
at least 10 000 rpm and sometimes as high as 20 000 rpm..
We service most automotive, motorcycle,
marine, iand many others fuel injectors. We also clean and service the new GDI (Gasoline Direct
Injectors) FSI (Fuel Stratified Injectors), HPI and JTS fuel injectors. Our cost effective ultrasonic
cleaning and electronic testing procedures will restore most injectors to a reliable factory new condition,

Fuel injector get dirty or become clogged
due to many factors some of which are hydrocarbons and additives, which all forms part of today’s
fuels. Improper use of fuel additives and in tank
cleaners, dirty fuel, fuel filters that collapse due to water in the fuel, poor maintenance, and many other
factors contribute to this problem. All vehicles are vulnerable to injector clogging, but the ones that are most
vulnerable and most likely to experience drivability and emissions problems are the older ones. Almost
all of today’s computer controlled engines monitor one or two oxygen sensors, placed in such a way that it can
only analyze the combined exhaust gases and not each cylinder, thus averaging the air fuel ratios. This can
cause some cylinders to run leaner and other cylinders to run richer, causing all kinds of drivability issues
and in some case even catastrophic engine failure. Dirty fuel injectors or clogged fuel injector can and
will cause catastrophic failure
How can you clean what you can not see?
Fuel injector cleaning chemicals, fuel tank
additives and fuel rail induced injector cleaners more often than not does not do a proper job of cleaning your
fuel injectors. In some instances some of the products might even be harmful to components such as expensive
catalytic converters and in other instances might actual cause the injector to clog by filling the filter basket
with debris. There is also no way to determine or confirm, if the flow patern has been corrected after
the on vehicle chemical clean.

"Off the Car" fuel injector servicing, in
the form of ultrasonic cleaning and flow testing, is the only reliable, accurate and precise way to verify that
each fuel injector is performing the way it should.

After Ultrasonic Cleaning:

When all cylinders are operating evenly, you can expect emissions, drivability,
peak performance and fuel economy to improve.
