Assuming you're not having problems with them missing, or hard
starting, yes.  But if I pulled them, I'd replace them.  You're
somewhere approaching the end of the expected life, they're a pain to
get at, and even if you buy 'em from a dealer, they're less than
airplane plugs.  Be certain to follow the torque specs, as the ford
engine is known for having plugs not come out.
