Zap Tester
This is not rocket science, but simply a portable electronic spark plug tester that enables you to observe the performance with the naked eye of your spark plug.
Zap Spark Plug Tester is the only portable spark plug tester in the world.
The objective has always been to try and eliminate guesswork and save lots of valuable time and frustrations.
For example: The gap size affects the plug’s temperature and voltage necessary to ignite fuel / air mix. It is also a misconception that spark plugs are pre-gapped from the factory. It is always necessary to check and re-gap spark plugs straight out of the pack.
A spark plug’s voltage requirement is directly proportionate to gap size.
The larger the gap, the more voltage is required to bridge the gap.
