High tech from the lab

NGK, the world market leader for spark plugs, has taken a big step into the world of high technology with the new Iridium IX spark plug. Laboratory tests have shown that Iridium turns a spark plug into a power spark plug. From space travel to the road, that is the quantum leap in spark plug research!

The secret of the new Iridium IX spark plug lies in the laser-welded electrode made of iridium. Due to its "minimal" diameter of only 0.6mm, it bounds the ignition voltage.

1. fuel saving due to generally better combustion
2. engine runs absolutely smooth, faster acceleration
3. rich ignition voltage, even at low voltage
4. prevents sooting, even when driving short distances
5. multiple lifetime compared to all standard plugs

Width across flats: 20.8mm
Thread diameter: 14.0mm
Thread length: 12.7mm
Electrode gap: 0.8mm
Resistance: suppressed, 5kOhm
