NGK Iridium-Spark Plug LMAR9AI-10

NGK 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.

• twice the service life
• better combustion
• prevents misfire
• Thread diameter: 10mm
• Thread length: 19mm
• Wrench size: 14mm
• Heat value: 9
• Electrode gap: 1.0mm
