Bosch OE iridium spark plugs combine a 360 degree continuous laser-welded iridium center electrode, with a laser-welded ground electrode—to provide unmatched quality and OE long-life performance. They feature a 0.6mm ultra-fine wire iridium center electrode to provide exceptional ignitability. The laser-welded electrodes offer more area for flame growth and increased durability. These plugs also have a nickel plated housing for superior resistance to corrosion and come factory set pre-gap for an easy installation. Order the Bosch spark plugs designed for fitment with your make and model.

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.

Champion Double Platinum Power spark plugs have platinum on both the center and ground electrodes for longer life with minimal wear. The center electrode is platinum fine wire that's riveted onto the nickel alloy center electrode—and the ground electrode has a pad welded to the surface. These spark plugs use a fine-wire and V-trimmed center electrode to create a sharper spark focus than conventional plugs. With their exclusive Heat-Active alloy, they reach operating temperatures quickly and maintain stable temperatures under varying engine loads. Widely designed for distributor-less ignition systems, Champion Double Platinum Power spark plugs can maximize fuel efficiency and spark energy.
