NGK LASER IRIDIUM

Compared to standard spark plugs, NGK Laser Iridium delivers superior fuel burn and a longer service life. With 6.5 on the ‘Mohs’ hardness scale, Iridium is the second-densest element to exist (after Osmium), yet it’s also the most corrosion-resistant metal (even at temperatures as high as 2000 C ). Thanks to Iridium’s excellent electrical conductivity, it’s the ideal metal to use in the manufacture of premium spark plugs.

The laser-welded platinum disc on the ground electrode provides extra durability, once again improving service life and bringing the wear rate down to a minimum. With both electrodes working in harmony together, your engine will have a more stable idle with superior anti-fouling, improved fuel efficiency and lower emissions.

Another great feature is that the ground electrode is also taper cut; in simple terms this is done to reduce as much obstruction as possible to the flame expansion (this reduces quenching) as it starts to burn from the electrode tips. This allows for a more complete, efficient burn, which in turn increases MPG.
