These spark plugs are designed and manufactured for not only high power applications but for factory replacement. These work for the M177, M176 and the M178 engine families. The factory plugs do not handle the high cylinder pressures very well and frequently result in misfire problems, even on unmodified vehicles.
NGK spark plugs are also 1 step colder to help prevent pre-ignition in engines that are making more power than stock allowing you to further push the envelope of your vehicle.
Description
Product Overview
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug)
is a device for delivering electric current from an ignition system to the combustion chamber
of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark,
while containing combustion pressure within the engine. A spark plug has a metal threaded
shell, electrically isolated from a central electrode by a ceramic insulator. The central
electrode, which may contain a resistor, is connected by a heavily insulated wire to the
output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed
into the engine's cylinder head and thus electrically grounded. The central electrode
protrudes through the porcelain insulator into the combustion chamber, forming one or more
spark gaps between the inner end of the central electrode and usually one or more protuberances
or structures attached to the inner end of the threaded shell and designated the side, earth,
or ground electrode(s). NGK spark plugs are designed and manufactured for not only high
power applications but also factory replacement. The factory plugs do not handle
high cylinder pressures very well and frequently result in misfire problems, even on unmodified
vehicles. The NGK spark plugs are also 1 step colder to help prevent pre-ignition in
engines that are making more power than stock allowing you to further push the envelope of your vehicle.
