NGK Spark plug GR8DI 12 90908 Iridium

NGK Spark plug GR8DI-12 IridiumNGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.Specification:Diameter: M14Spanner size: 14 Bi-HexSpark Plug: 1 - Earthed ElectrodeThread Size: 19Vehicle fitments and cross references are given as a guide. Please compare with your original part before fitting, and email us if you are unsure.

Longer service life: The use of the precious metal extends the service life of the spark plug compared to standard spark plugs. Optimised starting behaviour: The laser-welded, ultra-fine iridium centre electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. Economical in consumption: The excellent ignition capacity contributes to more efficient engine performance, reduces fuel consumption and environmental pollution. Note: Please observe the general installation instructions before installation! Scope of delivery: 1x NGK spark plug GR8DI-12 Laser Iridium
