🔧 Installation Tips & Help

Easy “swap & go” maintenance with a few key checks:

  • Check the Gap: Always verify the spark plug gap before installation for optimal performance.
  • Anti-Seize: A small amount of anti-seize compound on the threads prevents seizing in the cylinder head.
  • Torque Right: Use a torque wrench. Do not overtighten!
