Weistec's Mclaren Spark Plugs are designed and manufactured for higher power applications. The factory plugs do not handle the M838T or the M840T's high cylinder pressures very well and frequently result in misfire problems, especially on modified vehicles.

The Mclaren 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 M838T and M840T engines

  • Suitable for all M838T and M840T vehicles from stock to highly modified

  • Set of 8

* Important: Please be sure to check and set spark plug gap prior to installation.
