Pre-ignition is the ignition of fuel before the actual spark occurs, which causes a rapid temperature rise in the combustion chamber that can damage engine components and melt spark plug electrodes. Causes of pre-ignition include but are not limited to a buildup of deposits that can become incandescent in the combustion chamber, improper installation torque being applied to spark plugs, and having spark plugs with a heat range that is too hot for the engine's operating condition.
