Review on Autolite 86 4PK Copper Resistor Spark by Eric Montoya

Revainrating 1 out of 5

Worthless Spark Plugs!

When I tried this product, I was disappointed by the lack of improvement in my engine's performance .the only positive aspect was that they are affordable. However, after a few uses, they became unreliable and caused my engine to misfire. Save your MONEY and invest in better quality spark plugs..

Pros
  • - Copper core provides better performance and conductivity than standard spark plugs.
Cons
  • - Some vehicles may require a different spark plug, leading to compatibility issues.
