Spark Plug Tips
by Ron Bak

When purchasing new plugs, use the manufacturers specified plugs when possible, if not, then replace them with a well know brand such as champion, A/C Delco, Bosch, etc.

Don't waste money on hyped up, newest breakthrough in spark plug technology, these plugs rarely pay for themselves in fuel economy or longevity.

Check the plug gap against your cars' specifications, even if they have been preset. Used compressed air to blow out debris from spark plug holes before removing plugs. Pull on the plug boot, not the wire.

When replacing the spark plugs, use a small amount of anti-seize compound on the threads to avoid galvanic reaction with the cylinder head. Use a small amount of dielctric grease on the inside of the plug boot where the boot contacts the ceramic insulator of the plug.

Check the condition of the plugs to get an idea of what is going on inside the combustion chambers.
