Champion Copper Plus Spark Plug
Champion Copper Plus 807-1 is a standard replacement spark plug built with a copper center electrode for strong conductivity and heat control. It is listed for a wide range of motorcycles, snowmobiles, and small-engine applications, including Yamaha, Kawasaki, and Suzuki models.
Key Features
- Copper center electrode for consistent conductivity and thermal control.
- Standard replacement design for secondary ignition service.
- Flat seat with a 14 mm thread diameter and 0.5 in reach.
- Nickel ground electrode material with a removable nut terminal.
- Pre-gapped to 0.032 in for common service applications.
- Champion Copper Plus small-engine classification.
Detailed Description
The Champion 807-1 spark plug uses a copper core electrode to promote reliable spark transfer and controlled operating temperature, which helps support steady wear characteristics in regular service. Its standard replacement construction, flat seat, and 0.032 in pre-gap make it a practical choice for ignition maintenance on older powersports and small-engine equipment. This part cross-references L78C for the same application. For buyers searching for a Champion spark plug for Yamaha, Kawasaki, or Suzuki applications, 807-1 matches the Copper Plus line and the L78C interchange reference.
What It Is Used For
- Replacing a worn spark plug that no longer fires consistently.
- Restoring ignition performance after fouling or electrode wear.
- Addressing hard starting caused by degraded spark delivery.
- Supporting smoother combustion in older two-stroke applications.
- Maintaining service intervals on compatible powersports engines.
Installation Notes and Tips
Verify plug type, thread diameter, reach, seat style, and heat range before installation. Confirm the specified gap against the engine service manual if your application requires a different setting. Use the removable nut terminal only when the ignition lead calls for that configuration. For fitment searches, this part is listed for 2010-2012 Beta Mini Trials, 2008-2009 Hyosung SF50R/Rally, and multiple Yamaha, Kawasaki, Suzuki, Ski-Doo, and Abarth applications.
Quality Assurance
Champion Copper Plus is positioned as a standard replacement spark plug line with a copper core electrode for dependable performance and wear control. Part number 807-1 is also referenced as L78C.
This part fits 220 vehicles
