High-Tech straight from the lab
NGK has taken a massive step forward in spark plug technology with the new Iridium IX. Laboratory testing has shown that Iridium turns a normal spark plug into a ‘power plug’. A quantum leap from space travel to the road. The secret is in the 0.6mm laser-welded Iridium electrodes.
High fuel efficiency thanks to generally better combustion.
Outstanding acceleration and general engine performance.
Great striking voltage, even with lower power systems.
Prevents soot build-up, even on short journeys.
Longer service life and more durable than standard plugs.
Wrench size: 20.8mm
Thread diameter: 14.0mm
Thread length: 12.7mm
Electrode distance: 0.8mm
Resistance: interference suppressed, 5kOhm
OEM number for comparison purposes:
Denso: IW31 / W31ESG-U / W31ESRZ-U
BOSCH: W2CS
