These have been sitting in the glove box for 2 years now! I bought them
reconditioned from a FI shop in Florida. I drove with them in my WATER
COOLED `87 van for a few months and was told that I was given the wrong
injectors so there they sat unused. They worked fine when I uninstalled
them. Anybody interested in these? Make an offer. Pics avail on request.
Thanks! Mikey & `87 Westy Eeyore

Random web search on the p/n brought these up from a random internet
vendor...

Fuel Injectors - New - Genuine Bosch
Fuel Injectors can become clogged over a period of time or after a large
amount of miles. Many people do not realize how sensitive these beasts can
be. If loaded with junk, they can run either rich or lean, depending on
where the junk is.  The art of keeping these clean is to regularly change
your fuel filter and run a fuel injector cleaner at least once a month in a
tank of gas.
