FULL DESCRIPTION
NGK Iridium IX Spark Plug - SILMAR9A9S
The NGK Iridium IX Spark Plug represents the pinnacle of spark plug technology, engineered for exceptional performance and durability. Its ultra-small 0.6 mm diameter center electrode, made from fine wire iridium, is 25% smaller than platinum electrodes and significantly smaller than conventional nickel electrodes. This precision design reduces voltage requirements, enabling a stronger and brighter spark for precise ignition.
This spark plug features a metal shell plating for enhanced corrosion resistance and an extended service life. The laser-welded fine wire iridium center electrode combined with a platinum-tipped tapered ground electrode ensures reliable ignition and long-term durability. Optimized for extreme performance environments, the SILMAR9A9S delivers superior ignitability and efficiency. This spark plug is sold individually.
