Product Details

The Champion Copper Plus line focuses on dependable everyday ignition performance with a copper core that helps transfer heat efficiently while maintaining consistent spark delivery. Part number 415 uses a removable nut terminal, a hex design for standard service tools, and a resistor configuration suited to many OE-style ignition systems. This spark plug is listed across a wide range of vehicles, including long-tail fitments such as 1998-2000 Chevrolet Metro spark plug replacement, 1994-2000 Pontiac Firefly ignition service, and 1990-1999 Mitsubishi Eclipse spark plug applications.

This part cross-references Autolite 63 and Bosch 7900 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire complaints tied to aged secondary ignition components
• Reduced throttle response from degraded plug performance
• Ignition noise concerns in resistor-equipped systems

Installation Notes and Tips

Verify the plug type RN9YC, seat style, thread diameter, and reach before installation. Check the specified gap for your exact vehicle application, since listed fitments include different gap requirements such as 0.028 in, 0.032 in, 0.035 in, 0.040 in, and 0.044 in. Use the vehicle service specification for final gap setting and torque. Confirm that the ignition system calls for a resistor spark plug and that the terminal style matches the coil wire or boot connection.
