Product Description

The NGK CR8EIX (4218) Iridium IX spark plug is designed to provide exceptional ignitability, improved throttle response, and superior anti-fouling characteristics for high-performance engines. This spark plug features a fine-wire 0.6mm iridium center electrode that ensures high durability and a consistently stable spark, even under demanding conditions. The iridium alloy used in the center electrode has an extremely high melting point, making it well-suited for modern, high-output engines. The tapered-cut ground electrode design helps to maximize fuel burn, which can contribute to better acceleration and fuel efficiency. Built with a solid copper core, this plug offers superior heat dissipation and conductivity across a wide heat range. Its trivalent metal plating provides excellent anti-corrosion and anti-seizing properties, facilitating easier installation and future removal. This spark plug utilizes a 10mm thread diameter, 19mm thread reach, and a 16mm (5/8 inch) hex size. Please verify fitment for your specific application before purchasing.
