NGK Iridium IX spark plug reference 625TR7IX for RENAULT R21 2.0 Turbo

Iridium IX NGK spark plugs are the most technically mature spark plugs on the market.
They have a fine Iridium tip on the center electrode, which is laser-welded using a special process.

Iridium is a precious metal and one of the strongest materials in the world.
It begins to melt from 2450°C and is particularly resistant to electrical erosion created by sparks.

The service life of an Iridium spark plug is 2.5 times longer than that of a standard spark plug.

The use of Iridium allows :
- Reduce the central electrode to a very fine tip of 0.6 mm in diameter / optimization of flame propagation.
- Reduce the voltage required for ignition.
- Improve ignition in the combustion chamber. Easy starting.
- Reduced voltage required.
- Fuel consumption reduced by up to 5%.
- Better engine reactivity (up to 0.7 seconds gained on a 0 to 100 km/h).
- Anti-corrosion and anti-seize treated exterior.
- Reduced pollutant emissions.
- More stable engine idle speed with reduced vibrations.
- 2-step" technology: avoids clogging of the insulation by means of an electric arc cleaning process.
