NGK Iridium IX spark plug reference SILFR6A for SUBARU Impreza 2.5 16V WRX 300CV

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.
