If I were to use f22b2 wires in a f22b1 engine, what would happen? The guy at Napa screwed me over.

 

If they fit, use them. You'll be fine.

 

If you still have your originals you can compare them to the F22B2 set.

I don't have the two here to compare.... The wires will work. The issue would be whether or not they are the right size to go down into the valve cover.

 

if you can feel them snap or click into place on the top of the spark plugs they should function just fine.
