Can someone educate me on how to adjust spark plug gap when changing electrode type?
Vehicle in question is a 92 Civic with one of Honda's lean burn engines, and it's rather sensitive to changes in ignition. Stock plugs are NGK coppers gapped at 0.032". Hypothetically, if I changed them out for iridium or platinum plugs, how would the gap need to change? This engine is old enough to have still been using a distributor, so I imagine the specs from a newer variant that calls for iridium plugs and uses COP would not be appropriate.
