i remember reading about some special gapping tool for these plugs but no one could ever answer what it looks like or where to get one.

Everyone says that they are properly gapped at .32 from factory. However, the batch I checked were between .20 and .25.

I have had NGK "pre-gapped" iridium spark plugs be off a little as well. Just use feeler gauges and fix both ground electrodes to the proper setting. Careful with iridiums though as the center electrode can snap off if you're not careful.
