Discover NGK Iridium DILKAR7C9H spark plugs, specially designed for Renault Clio IV RS models. These plugs represent the pinnacle of technology on the market. With an ultra-fine, precision laser-welded iridium central electrode, they offer unrivalled performance. Iridium, a precious and extremely strong metal, withstands temperatures of up to 2450°C and effectively combats electrical erosion caused by the spark.
Iridium plugs have an impressive service life, lasting 2,5 times longer than conventional plugs. Thanks to iridium, they allow you to:
- Reduce the thickness of the central electrode to just 0,6 mm, optimising flame propagation.
- Lower the voltage required for ignition.
- Improve ignition in the combustion chamber, making starting easier.
- Reduce fuel consumption by up to 5%.
- Increase engine response, with a gain of 0,7 seconds in a 0 to 100 km/h run.
- Protect against corrosion and seizure thanks to a special exterior treatment.
- Reduce pollutant emissions.
- Stabilise engine idling, reducing vibration.
- Incorporate "2 steps" technology, which prevents insulator fouling through electrical arc cleaning.
Compatible with Renault Clio 4 RS M5M 400 engines from 2013 and Nissan Juke NISMO MR16DDT engines from 2012, these plugs are the ideal choice for improving your vehicle’s performance.
