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.

Solid Job All Around
Cleaned the injectors on my truck and boat—both are running like they should now, smooth and strong. Quick turnaround, kept me updated, no surprises. Would definitely recommend. 10/10.

My motorcycle had a fuel injector that was completely clogged, and instead of buying new two new ones for $200 and waiting a week to have them delivered, I took them to InjectorRx. For same day service, it was $60. I popped them in the motorcycle and the bike now runs like new. New O-rings came with the injectors, and the gentleman working called me twice to update me on progress throughout the day. I don’t think I’ll ever buy new injectors again. Thanks very much!
