NGK Laser Iridium spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris; this decreases the required voltage to bridge the spark gap. An iridium disc is welded on the center electrode and a platinum disc is welded on the ground electrode, reducing the wear rate of both surfaces and ensuring great durability and long life. These spark plugs are available for use with a variety of engine types.
