Review on Autolite 258-4PK Copper Non-Resistor Spark Plug: 4-Pack for Optimal Performance by Adam Mazie

Revainrating 5 out of 5

Autolite 258 for spark plugs

Ordered and arrived 3 days late USPS. I installed 2 of these on my 20hp Agco Allis Simples liquid cooled engine. Kawasaki and it runs very smooth. I am very happy with these spark plugs, this tractor has never worked so well, even with ngk spark plugs. I saved this page so I can order more in the future.

Pros
  • Cold formed steel body and precision rolled threads with solid end stud for strength
Cons
  • Some imperfections
