What is the gap setting on an Autolite?
Autolite doesn’t recommend adjusting the plug gap more than . 008″ in either direction. Beyond that slight adjustment, the ground electrode and center electrode won’t align properly, hindering spark plug performance and drastically reducing plug life.
Do Autolite plugs need to be gapped?
Autolite® and all spark plug manufacturers offer spark plugs pre-gapped in the most popular gap sizes. Because of the many gap sizes required, no one offers spark plugs properly gapped for every application. Gapping has always been the job of the installer.
What should the gap be on my spark plugs?
For most racing applications, you usually want the plug gap to be between 0.020 and 0.040 of an inch. Most engine builders seem to settle around 0.035 of an inch. Factors such as the type of ignition you run, cylinder heads, fuel and even timing can affect how much gap will work best for you.

Gapping the plugs to your engine’s specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy.
Can you gap double platinum spark plugs?

How long do Autolite platinum plugs last?
Installing a single platinum plug in place of a copper core spark plug will result in a 50-60,000 mile service life, a nice upgrade for your customer.
What happens if spark plug gap is too small?
One of the key factors that makes a spark plug work well, or not, is the size of the gap between the electrodes. If the gap is too small, the spark will likely be too weak and cause the engine to run poorly or with poor efficiency.
