Plug gaps

The general consensus is you should always check spark plug gaps when installing new plugs. The time to do this is minimal and should be automatically done. I have been surprised more than a few times at the inconsistencies discovered, regardless of the manufacturer.

For this you can use any type gauge on new plugs, but only a wire gauge on used ones because the ground electrode wears unevenly through use.

For new plugs I prefer a round gauge with a tapered ramp so you can quickly insert it and rotate to get your reading.
