Welcome to Dano-performance.  We are a fuel injector cleaning company specializing in Bosch and Siemens injectors for stock and modified European cars.  We can service other cars that use Bosch and Siemens injectors, so please contact us to see if we can help you.


The overall process is an involved one, but it insures your injectors are returned to you performing back up to factory specs.  The injectors are tested and externally cleaned when they arrive to see if there are any problems with them. Then they are cleaned in an ultrasonic bath and then they are backflowed on the machine to remove any particles that may be trapped in the injector.  Then they are tested again after cleaning.  If they are not performing well enough, they are cleaned again.  Your injectors should be flowing within 2% of each other for best economy and performance.  Once they are performing well, they are painted and come with all new oring, pintle caps, and filters.


We also offer flow matched sets for certain cars.  See our “Flow Matched Injectors” for more information


The usual process takes 2 to 3 working days.  Don’t want your car sitting in your driveway for a week with no injectors?  Please see our “Loaner Injector” page.
