I read this article on the Hot Rod Mag. and want everyone input:
"Savyy hot rodders know better. If the rest of the ignition system is functioning properly, baseline new plugs using the manufacturer's spec, 0.040" for example, then open the gap to 0.050" and test performance. If the engine feels more responsive and the ignition doesn't misfire at high speed, you've made progress. Try increasing the gap another 0.010" and test again. The point is, wider gaps improve combustion as long as the ignition system can bridge the gap. Along with gains in power, lager gaps even increase fuel economy, although such gains usually requre at least a 1k-mile test loop at each gap-setting to yield a consistent pattern."
Another article I read on the NET
"The rule of thumb on plug gaps is to open them up in 0.002" increments at a time. When the car begins to lose power or slow down the go back 0.001"-0.002" and this in most cases is the optimum gap. It is important NEVER TO GO MORE THAN PLUS OR MINUS 0.008"."
I think 0.002" increments is the safer way to increase the plugs gap. Does any body done this?
