Champion 347 Spark Plug

Champion Copper Plus 347 Spark Plug

Champion Copper Plus 347 is a resistor spark plug built for dependable ignition performance and consistent heat control. Its copper core electrode helps improve conductivity, while the nickel center and ground electrode materials support steady wear characteristics in everyday driving.

Compatible With long-tail applications such as 2002-2012 Jeep Liberty spark plug replacement, 2002-2010 Dodge Ram 1500 ignition service, and 2001-2005 Lexus IS300 tune-up maintenance, this plug is also listed for select Toyota Camry, Dodge Dakota, and Jeep Grand Cherokee applications. Part number 347 is identified as Champion plug type RC10MCC.

Key Features

• Copper core electrode for improved conductivity and heat control
• Nickel center electrode tip and nickel-copper alloy ground electrode material
• J-gap design with a single ground electrode
• Resistor type plug for ignition system noise control
• Flat seat design with 0.75 reach and 14 mm thread diameter
• Pre-gapped at 0.030 in. per listed specification
• Champion Copper Plus classification

Product Line Details

Champion Copper Plus is the brand’s copper-core spark plug line focused on stable ignition performance and controlled operating temperatures. For drivers servicing a Jeep Liberty, Dodge Nitro, or Lexus GS300, the Copper Plus design provides a straightforward OE-style service plug format with a conventional nickel electrode setup.

Detailed Description

Champion 347 uses a copper core to move heat away from the firing end more efficiently, helping maintain consistent spark plug operating conditions. The J-gap ground electrode, non-removable nut terminal, and resistor construction make it a practical choice for routine ignition maintenance across a wide range of vehicles, including Jeep, Dodge, Ram, Toyota, Lexus, Volkswagen, Scion, and Pontiac applications listed in the fitment data. This part cross-references Autolite 5224 and Bosch FGR8KQE0 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent ignition firing
• Misfire conditions related to degraded plug electrodes
• Reduced throttle response from weak spark delivery
• Maintenance replacement for scheduled tune-up service

Installation Notes and Tips

Verify the vehicle-specific gap and plug type before installation. Listed fitment includes applications such as Fits 2002-2012 Jeep Liberty, N/A; Fits 2002-2010 Dodge Ram 1500, N/A; Fits 2001-2005 Lexus IS300, N/A; and Fits 2002-2006 Toyota Camry, N/A. Some applications note different gap requirements, including 0.044 in., 0.032 in., 0.028 in., or 0.032 in. depending on the vehicle. Confirm thread diameter, reach, seat type, and heat range against the engine specification before service.

Quality Assurance

Champion spark plugs are built to meet established ignition service requirements with materials selected for conductivity, heat management, and wear consistency. Part number 347 is a direct replacement-style spark plug for the listed applications and is identified by plug type RC10MCC.
