028″ which is roughly 0.7mm. Be careful gapping iridium plugs. If you have to open the gap you need to use something that pulls the ground electrode rather than wedging something in to pry it apart or you can damage the iridium tip. Smoking section, please.

What happens when spark plug gap is too large?

The Spark-Plug Gap However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn’t run at all.

What happens if point gap is too small?

This does not give the coil sufficient time to charge, resulting in a weak spark. It also slightly retards the timing. In short, either too wide or narrow a point gap will cause a misfire under load.
