About this product
About this product
The Champion Copper Plus™ spark plug delivers dependable performance and long life for your motorcycle. Built with a copper core center electrode, this spark plug offers superior heat control, optimizing engine performance and extending the spark plug's lifespan.
Description
Champion Copper Plus™ spark plugs are engineered to provide reliable ignition and consistent performance. The copper core rapidly dissipates heat, preventing pre-ignition and fouling, which contributes to smoother idling and improved throttle response. A patented SAC-9 semi-conductor resistor ensures maximum suppression of electromagnetic (EMI) and radio frequency interference (RFI), safeguarding sensitive electronic components on your motorcycle. The patented Ultraseal™ coated shell provides exceptional resistance to rust and corrosion, ensuring long-lasting durability even in harsh environments. Champion spark plugs are manufactured in the USA to exacting standards.
