Probably not as good as removing the manifold and cleaning it thoroughly, but it saves labor.
I bought it to decoke my kids direct-injection A4.

Interesting, never heard of it, I already have the parts off the car for another project so probably going to do it by hand.
I am planning on cleaning the injector o rings with a silicon spray and then using to it grease them up before re installing the rail
