Champion Platinum Power spark plugs use a platinum pad welded to a nickel alloy center electrode for long life. The advantage of this design is that platinum has extremely good wear characteristics and can reduce gap growth.
Features and Benefits Include:
Maintains stable operating temperature under all engine loads
Heat-active alloy allows electrodes to reach optimal temperature
Platinum tipped center wire resists wear and helps to maintain proper gap spec over the life of the plug
Exclusive thin-wire center electrode and V-trimmed ground electrode creates sharp spark focus and less spark scatter
