Iridium spark plug - iridium power

Six times harder than platinum, iridium withstands temperatures of up to 4,000°F.
Due to the iridium electrodes of these spark plugs being reduced to just 0.4 mm, voltage requirements are lowered and ignition performance is improved.
The 360° laser-welded electrode provides wear-resistant sealing even under the harshest conditions.
Mass electrode with a conical cut and U-slot, creating a wide area for the flame core.
