Bosch 4418 gap ?

Yes some plugs tend to break very easily (damage at the center insulator) if one attempts to change the gap.
But "gap spec" depends on the ignition system, not the manufacturer; though hopefully the manufacturer is aware of - and has designed for - a particular application.

To actually answer the question, an 1100's gap should be at 0.031".

If the little box has been handled poorly (or dropped), the outer electrode may be bent in too far - yes it needs fixin', just use caution. I seriously doubt any vendor would accept a return on any plug.
