New Bosch Plugs Not Gapped Correctly???
Hi there. I'm about to do the 12K service, and have a question about the stock bosch plugs. They're supposedly set by the factory at 0.6mm, when the manual calls for 0.8mm.
However, I can slide my 0.8mm feeler gauge between the tips of the arched ground electrodes and center electrodes, telling my they're at least 0.8mm, and not 0.6mm, since the curvature of both ground electrodes seem to follow the curvature of the center electrode, maintaining the same gap. Or am I missing something else? How else do you measure the gap on these things?
Would like to hear from those using bosch plugs. Thx.
