Top Quality Fuel Injector Cleaning & Flow Testing

Professional Solutions for Dirty, Clogged, and Leaking Injectors

Starting at $22.00 per manifold injector or $30.00 per direct injector, we service, flow-test and restore your gummed up, clogged, dirty or leaking injectors to operate like new. Why pay 4 – 16 times more for a new injector or 3+ times the amount for remanufactured fuel injectors when you can simply restore your current injectors to like-new condition? We will save you money with our OEM-approved ultrasonic fuel injector cleaning and flow testing process. Best of all, we guarantee our work! If we cannot restore your fuel injectors to function like new, you will not be charged for the time spent on those injectors we were unable to clean.

We do not serve diesel injectors or spider assembly injectors.
