THE thermal theory of ignition of gases explains certain phenomena in the ignition of explosive mixtures by electric sparks involving capacitive and break or make discharges. However, a number of ...

Platinum spark plugs are already a step up from copper. Double platinum plugs might seem like a straightforward upgrade, but ...

Spark plug indexing sometimes is necessary to avoid side-electrode contact with high-dome pistons. Moroso offers different thickness spark plug washer kits to do this. Some theorists claim positioning ...
