Heat ranges

By Dan Davis - 06/07/2001 3:52:53 PM; IP 63.119.36.179

Oooohhhh, no. Don't do that!

Heat ranges signify how far the plug protrudes into the chamber. Low compression/low performance likes a hot plug to keep it cleaner due to lower combustion temps & pressures. High compression/high performance engines use cold plugs to avoid pre-ignition caused by the plug becoming overheated.

Running too high a heat range plug can cause all kinds of nasty things: tip can hit the piston, pre-ignition can destroy the engine (similar to detonation) to name two. Too clod of a plug will foul out quickly but not cause any engine damage.

Cheers,
Dan
