This is an example of the different duty cycles we use to flow test and clean a gasoline direct injector. RPM levels from 250 all the way to 7400, done with a sequential firing order. On a standard injector it’s 10,000 RPM with a batch firing order. Now is the time to get your maintenance done because summer is right around the corner.

This is a set of Bosch EV1 hose fed 036 injectors before cleaning. A couple leak pretty bad. This set was cleaned and flowed, all to the OEM specs and returned to another satisfied customer.

These injectors are Bosch EV1 with the blue plastic pintle caps removed. This shows how the pintle valve protrudes out of the end of the injector. The pintle caps are for protection purposes. When they are used without these caps installed, this valve can be easily damaged. The picture and video shows one that has been damaged and how the delivery rate has been drastically affected. Unfortunately this injector could not be fixed.

I can't stress the importance of treating your fuel with stabilizer. A little effort pays dividends down the road and helps eliminate costly repairs. This is an Optimax fuel rail and the side feed injectors.

This is pretty common for what I'm seeing on customer's injectors. The picture on the left is what the injector flowed BEFORE cleaning. The picture on the right shows the dramatic difference in increased flow after the cleaning process was done. Keep SPI in mind for all of your injector needs.
