Review on Autolite Copper Resistor Spark Plug by Chris Lee

Revainrating 5 out of 5

Excellent Performance Spark Plug

As a result of my tests I determined that this spark plug delivers reliable ignition and improved fuel efficiency. The copper resistor design ensures better conductivity for a smoother ride. The only downside is that it may not be suitable for high-performance engines..

Pros
  • Reliable ignition, improved fuel efficiency
Cons
  • Not suitable for high-performance engines
