Review on Autolite XP3923 4PK Iridium Spark Plug by Charles Lewis

Revainrating 1 out of 5

Check spark plug gap

Two were slightly larger so needed some bending. It is highly recommended to check them with a gap first, but don't increase the gap as the iridium tips are thin. The price was great as a 4 pack was less than 1 pack at the dealership. For the night there were only traffic jams, so I took a chance. 30 km driven, so far so good.

Pros
  • Engineered for increased overall durability and virtually no gap erosion for longer spark plug life
Cons
  • Fits
