HKS Super Fire Racing M35G Iridium Spark Plug (NGK 7, 20.8mm Hex) - 10 Pack

The HKS Super Fire Racing M35G is a G-type iridium spark plug with an NGK 7 equivalent heat range — the warmest M-series step — and the larger 20.8 mm hex required by certain engines. The 0.6 mm iridium center electrode and platinum-chip outer electrode deliver strong ignition and long life, with thermal-edge anti-fouling. Sold as a 10-pack (wholesale case); a typical engine needs one plug per cylinder.
