    What will happen if the spark plug gap is wrong?

    An engine that hesitates, or stumbles, upon acceleration is often the result of incorrectly gapped spark plugs. If spark plugs are gapped too wide, the ignition spark loses some of its strength as it crosses the spark plug gaps. This can result in engine hesitation.

    The main difference is the material that the ‘tip’ of the spark plug is made of – normal ones are usually copper, whereas the other two have tips made out of platinum or iridium.
