Review on Champion Copper Plus 443 Spark Plug – Performance and Durability in a Carton of 1 by Jason Pinkney

Revainrating 4 out of 5

Good spark plug good for spark plugs

These are OEM spark plugs for my Dodge Stratus. Do what they are made for. My Subaru Forester taught me how to use OEM spark plugs. I upgraded the Forester to platinum spark plugs and the engine would idle intermittently and periodically stall. Went back to OEM (copper core) and had no problems. I know two different cars but have been told that ignition systems can be designed with specific spark plugs and may perform poorly if you use a different style due to the voltage requirements of the spark plug. From what I've been told, my experience shows that it can stand up to criticism.

Pros
  • Ignition parts
Cons
  • Long delivery time
