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 service 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 diesel injectors, Piezo injectors or GM Vortec Spiders.

We Service Gasoline Direct Injection
Picture
We have updated our shop with a new ASNU GDI Classic fuel injector flow bench to service the recent technology in fuel injection. Direct injection is here to stay. It provides good power and economy, however because the injector discharge nozzle is in the combustion chamber they tend to foul and cause performance problems. We service any direct injector except for Piezo injectors used on some of the European vehicles. If you are unsure of what type you have, send in this contact form and I'll verify your application: Direct Injection We do replace the compression seal and fuel seal. See this video for more details Parts Replaced

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.

What is Fuel Injector Service?

Fuel injector service is called many things which can be misleading; fuel injector rebuild service, fuel injector rebuild, direct injector rebuilding, injector reconditioning, fuel injector remanufacturing or remanufactured injectors. These terms don't best represent what the process is. The best term that represents the actual process is "fuel injector service." Your injectors are not disassembled, none of the internal hard parts are replaced, the injectors are ultrasonically cleaned and tested to assure their performance. The soft parts are then replaced.
