spark plug NGK iridium DPR7EIX9

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.
