Excellent, thanks.
I would offer this info: a NGK engineer advised that the fine tip plugs require less voltage to fire. Sparks can more easily jump from points than blunt tips.....and it is often beneficial to run a larger gap with fine tip. But then some fine tip / precious metal plugs have specific warnings not to regap...probably since damage could easily occur.

As for gap, If you increase it, they say it helps low end torque. At high RPM you want it smaller to prevent mis fire.
