Easy and effective to use.
Highly recommend this if you are running E85 . I pre soaked the injectors overnight in ultrasonic cleaning solution and just that I believe softened and took a lot of gunk off. Then I ran them in the Autom ultra sonic cleaner machine and even more came out . I plan to use this every 15,000 miles on my injectors now as the DI injectors cost $1,100 USDA to replace. I plan to clean my old DI injectors and see if they work. You do have to do a little research to the the flow rate of the injectors when doing the flow test with the machine. I plan to run a pre flow test with the old DI injectors and another after cleaning them . If this machine ever breaks, Iโm getting another one and getting one of the upgraded ones. Definitely worth the money.

Great for the neighborhood mechanic
Works great. Easy set up and to use. Easy to clean. Compact so it doesn't take up much workbench space. I use it so much we leave it set up. Clean injectors very nicely.
