NGK Iridium IX Spark Plug - CR8EHIX9 (3797) Key Features: Iridium Electrode: The iridium center electrode is 25% smaller than platinum and just 1/4 the size of a conventional nickel electrode, offering superior strength and durability. Reduced Voltage Requirement: The ultra-small diameter (0.6mm) center electrode reduces the voltage needed for ignition, extending the ignition system's life. Brighter, Stronger Spark: The smaller electrode design allows for a brighter and stronger spark, improving engine performance. Enhanced Performance: The tapered cut ground electrode helps reduce quenching and improves flame core growth, which leads to better ignitability, increased acceleration, and improved fuel efficiency. Anti-Corrosion Metal Shell: The new metal shell plating enhances anti-corrosion qualities, ensuring reliable operation even in harsh conditions. Longer Life: The durability of the iridium electrode, along with the fine wire design, ensures the spark plug lasts longer compared to traditional plugs. Specifications: Heat Range: 8 Thread Size: 10mm Reach: 19mm (3/4") Hex Size: 5/8" (16mm) Seat Type: Gasket Gap: 0.035" (0.9mm) Thread Type: Half Thread (12.7mm / 1/2" threaded) Terminal Type: Stud Terminal Threads (Terminal Nut not included) Type: Resistor Weight: 0.12 lbs Units Sold: Single Alternate/OEM Part Numbers: 3797, CR8EHIX-9 Part No.: 37-CR8EHIX-9 Applications: Honda: 1990–1989 Honda CB400F CB-1 2006–2002 Honda CB900F 919 2007–2002 Honda CHF50 Metropolitan 2005–2004 Honda CHF50P Metropolitan II 2007–2003 Honda FSC600 Silver Wing 2007–2003 Honda NPS50 Ruckus 2002–1992 Honda ST1100 2006–2003 Honda ST1300 2003–1990 Honda VF750C Magna 2000–1996 Honda VF750C2 Magna Deluxe 1990–1989 Honda VTR250 Benefits: Improved Engine Performance: The fine wire electrode and tapered ground electrode combination enhances the ignition spark, which improves acceleration, fuel efficiency, and overall engine performance.
