NGK CR10EIX Iridium Spark Plug – 6482 The NGK CR10EIX is a high-performance iridium spark plug designed for consistent ignition and long service life. It features a fine-wire 0.6mm iridium center electrode for reliable combustion and improved throttle response. The tapered cut ground electrode reduces quenching, while the high-alumina ceramic insulator ensures strong resistance to heat and vibration. This plug is a direct replacement for many applications and a common upgrade over standard copper plugs in the Suzuki DR650 and other motorcycles. The CR10EIX offers better resistance to fouling and wear, especially in off-road or dualsport conditions.
