• Up to 26% quicker engine starts compared to standard non-fine-wire spark plugs (independent lab tested)
• Up to 21% fewer hydrocarbon emissions than standard plugs, supporting better fuel efficiency and horsepower
• Copper core center electrode with iridium tip for optimal heat transfer and long service life
• High-alumina multi-rib ceramic insulator provides excellent thermal conductivity and superior electrical insulation
• Focused ignition design resists fouling for dependable starting in all seasons and weather conditions
• Built-in resistor suppresses ignition interference
• Flat seat with 14mm thread diameter, 0.75-inch reach, and 21mm (13/16 in.) hex
• Pre-gapped at 0.034 inches for straightforward installation

With a manufacturer heat range of 10 and a non-removable nut terminal, the XS63 is a direct OE-quality replacement for select Arctic Cat, BMW, Gas Gas, Kawasaki, Moto Guzzi, Sea-Doo, Ski-Doo, and Yamaha powersports applications.
