I have two set of injectors/One has a A at the end of it the other ends with a B. been told one means 8 degree the other 25 degree.anyone know.Tried local HD dealer,goodthing I need something else other wisw would have just wasted the gas.

 

Dont remember the part #'s off hand and all that info is at work but 25 degree injectors have "25 deg" printed on them under the part #!

A part # that is only different by an "A" or "B" on the end is the same part with a new revision to it. The 25 deg injectors are a different part # than the 8 deg!

 

here yah go Todd
