Haven't used them myself, but the mechanic I had the truck at, did--and he used them and didn't say anything about them being difficult to use or anything like that. All he said was that the first injector he tried was the bad one. So I guess they're straightforward to use. I was surprised that there are two pieces to these things. I guess that's to allow for a bit of alignment.


Perfect

I had a fuel knock for a while. Injector kill test only goes so far. Got 2 of these plugs and they found my problematic injector. This tool saved my truck from going to a new owner lol


Awesome

Product worked great, however I wish I knew exactly what to look for once I capped off each fuel rail. I think there needs to be instructions on what to listen/look/feel for when using this. I think I have the bad injector isolated, but am not sure. But it did its job without a doubt.
