Product Information

Weistec M157 / M278 spark plugs are designed and manufactured for not only high power applications but also factory replacement. The factory iridium plugs do not handle the M157’s high cylinder pressures very well due to the very small electrode tip and frequently result in misfire problems, even on unmodified vehicles.

Our silver core BOSCH spark plugs can support significant increases in power while operating perfectly under normal driving situations. The M157 / M278 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.

KEY FEATURES:

  • Higher Output for High Boost Applications

  • Colder range for better performance with increased horsepower levels

  • Direct replacement / bolt in for M157 / M278 engines

  • Silver core spark plug provides significantly improved performance over iridium

  • Suitable for all M157 / M278 vehicles from stock to highly modified

  • Set of 8
