Champion Copper Plus 301 Spark Plug
Champion Copper Plus 301 is a resistor spark plug built for dependable ignition performance and stable heat control. Its copper core electrode improves conductivity, while nickel center and ground electrode materials support consistent wear in everyday driving.
Compatible With a wide range of OE-style applications, including Geo Metro, Suzuki Swift, Mitsubishi Mirage, and Nissan Sentra, this plug is a practical choice for older import and domestic engines that call for the RN9YC4 style. Champion 301 is also referenced by plug type RN9YC4 for direct application matching.
Key Features
- Copper core electrode for improved conductivity and heat transfer
- Nickel center electrode tip and nickel copper alloy ground electrode
- Resistor design for reduced electrical noise
- Flat seat construction
- Removable nut terminal for flexible connection styles
- Pre-gapped at 0.041 in. / 1.05 mm
- Champion Copper Plus classification
- Part number 301 for easy catalog matching
Product Details
Champion Copper Plus is the brand line focused on copper-core spark plugs for steady ignition performance and controlled operating temperatures. On this Champion 301 spark plug, the copper core helps move heat away from the firing end, while the nickel-based electrode materials support reliable service in engines that specify an RN9YC4 plug type. The 14 mm thread diameter, 0.75 in. reach, flat seat, and resistor construction make it a straightforward OE-style replacement for many compact cars and light trucks from the late 1970s through the 1990s. This part cross-references NGK RN9YC4 for the same application.
What It Helps Address
- Hard starting caused by worn or inconsistent spark plugs
- Rough idle from weak ignition output
- Misfire concerns tied to aged secondary ignition components
- Reduced throttle response from degraded plug performance
- Service intervals on vehicles that use the RN9YC4 plug type
