I can't believe I have to post for this, but I just picked some Motorcraft SP-500 AGSF22FM plugs for my 2000 Ex SOHC, and the gap spec is .052-.056. I can't find a gap gauge anywhere that goes higher than .045. How do I measure this? I tried to search on info that says they may ship with a certain gap and the best I came up with is one reference to them being .054, but not a reference I'd want to count on. Worst case I can slap them in as is and they'd be a big improvement over the nubs left on the current plugs.
