Federal-Mogul designs Champion Truck Plug spark plugs specifically for the severe demands that pickup trucks and sport utility vehicles place on spark plugs. The massive center and ground electrodes are 20 percent larger than ordinary spark plugs, providing high conductivity between the gap and more dependable performance than ordinary spark plugs.

In addition, we strengthen the plug with a zirconia-enhanced insulator that offers 40 percent more strength than other spark plugs. This provides durability and long life under severe and continuous driving conditions.

The electrodes on Champion Truck Plug spark plugs feature the exclusive Heat-Active™ alloy to reach operating temperatures quickly and maintain stable operating temperatures under varying engine loads.
