The more power the coil has (determined by saturation not decal as to max voltage) the wider the spark gap. Power is volts times amps, and for most electronic ignitions you get more power than points. So 0.045 should work just fine. An electronic ignition box gives you the same power as a nonignition box, it just fires the plug two or three times instead of only once so there is more "fire in the hole".

Remember that is .045 and not .45. That would be the biggest plug gap ever heard of! Shocked Just messin, Adam
