Champion Copper Plus Spark Plugs

4.82 out of 5 stars 176 Customer Reviews

Champion Copper Plus spark plugs have been original equipment on a wide variety of engines for many years. They feature nickel alloy centers and ground electrodes with efficient wear characteristics. In addition, the spark plugs' extrusion of copper into the center electrode allows for increased conductivity and heat control. Manufacturers have used them in non-automotive applications, such as lawn and garden and other power equipment. Replace your old plugs with Champion Copper Plus spark plugs for maximum reliability.
