Review on πŸ”Œ Autolite XP6203-4PK Iridium XP Spark Plug Set (Pack of 4) by Samiran Pusarla

Revainrating 1 out of 5

NOT compatible with Mitsubishi Outlander GT or other high temperature engines

These spark plugs literally started to melt when installed and used in a 2014 Mitsubishi Outlander GT (6 cylinder). My GT first started cornering misfire after a few months and recently had an engineer code indicating a faulty spark plug in cylinder #5. Three of the six Olugs suffered significant heat damage during removal. My mechanic (whom I did not consult about these spark plugs - lesson learned) told me that Autolite spark plugs have been known to fail within 1-2 years. I would not recommend our pursuit of these forks for any application.

Pros
  • Satisfied so far
Cons
  • Wrinkled
