We service gasoline fuel injectors using the ASNU ultrasonic flow bench and service machine. Why buy reconditioned fuel injectors when we can make yours like new again.

Fuel injectors rarely die. They just get dirty. Fuel injector cleaning restores them back into like new condition and performance. Your injectors are cleaned and flow tested on the ASNU flow bench and ultrasonic cleaning machine. After cleaning new injector parts including filters, o-rings, spacers and pintle caps are installed. They are returned with a before and after flow report. Notice: We don't service direct (GDI) injectors or diesel injectors

What is ASNU Injector Service
ASNU injector repair service is a fuel injector cleaning process. It begins with injector flow testing and ultrasonic cleaning.  Ultrasonic cleaning brings the injectors performance back to like new or good as new condition. That's where the ASNU name came from. Good as new. Servicing your injectors is preferable to reconditioned fuel injectors. Your high quality original equipment injectors just need a good ultrasonic cleaning and quality injector flow testing to ensure performance. New injector parts including pintle cap, spacers, filters and orings are installed to bring them back like new. Good ASNU and better than reconditioned fuel injectors.

Why Not Clean Injectors On The Car?

Without a flow bench it's just a guess!

On the car fuel injection cleaning might be a good idea for maintenance but it doesn't get the injectors perfectly clean like ultrasonic  cleaning does. Our experience in the shop with the flow bench has shown some injectors to be stubbornly dirty and difficult to clean. Even if you get them clean enough to solve a misfire are they up to 100% for power delivery? Without a flow bench it's just a guess.
