Review on Autolite 425 4PK Copper Resistor Spark by Bruce Ingram

Revainrating 5 out of 5

Reliable Spark Plugs

After trying these spark plugs my car is running smoother than ever.The ignition system on my car was struggling to perform, but adding Autolite's copper resistor spark plugs made all the difference. My engine now starts with ease and the improved conductivity ensures that every cylinder fires properly. The only downside to these spark plugs is that they may not be suitable for high-performance vehicles or those with more demanding ignition systems..

Pros
  • Improved engine performance and easier starting
Cons
  • May not be suitable for high-performance vehicles
