Champion 7346 Spark Plug

Champion Double Platinum Power Spark Plug 7346

Champion Double Platinum Power spark plug 7346 is built for drivers who want stable ignition performance and long service life. It uses platinum on both the center and ground electrodes, along with Champion’s Heat-Active alloy, to help deliver a sharper spark focus and consistent combustion.

This plug is a direct-fit style option for a wide range of import and domestic applications, including Mitsubishi Outlander Sport, Mitsubishi Lancer, and Volvo XC90 service needs where the specified gap and plug type match the vehicle requirements.

Key Features

• Platinum fine-wire center electrode for precise spark delivery
• Platinum pad ground electrode for extended wear resistance
• Heat-Active alloy construction for responsive ignition performance
• Resistor design for reduced electrical noise
• Flat seat design with 14 mm thread diameter and 0.75 in reach
• Pre-gapped at 0.041 in, with vehicle-specific gap requirements noted in fitment
• Champion Double Platinum Power line for OE-style service applications

Product Details

Champion 7346 is a Double Platinum Power spark plug engineered around platinum-to-platinum electrode construction. The fine center electrode helps concentrate spark energy, while the platinum ground pad supports durability under repeated firing cycles. The plug uses a non-removable nut terminal, hex design, and resistor configuration, with RC10PYP4 plug type identification for application matching. This part cross-references NGK 5874 and Bosch 41913 for the same application.

Compatible vehicle coverage includes Fits 2011-2020 Mitsubishi Outlander Sport, N/A; Fits 2011-2017 Mitsubishi Lancer, N/A; Fits 2005-2011 Volvo XC90, N/A; and Fits 2007-2010 Volvo S80, N/A. Additional fitment spans Chevrolet Cobalt, Hyundai Tiburon, Suzuki Swift, Acura Integra, Nissan Sentra, Toyota Supra, and other listed applications.

What It Helps Address

• Hard starting caused by worn spark plug electrodes
• Misfire conditions related to weak or inconsistent spark
• Rough idle from degraded ignition performance
• Reduced throttle response from aged secondary ignition components
• Service intervals where platinum plug durability is preferred

Installation Notes

Verify the vehicle’s required plug type, thread reach, seat style, and gap before installation. Some listed applications require a 0.044 in gap, while others specify 0.039 in, 0.040 in, or 0.050 in; follow the vehicle service specification rather than the pre-gap alone. Confirm the RC10PYP4 application match for Mitsubishi Outlander Sport, Mitsubishi Lancer, Volvo XC90, and other listed vehicles before installation.

Quality Assurance

Champion’s Double Platinum Power line uses platinum electrode materials and Heat-Active alloy construction to support consistent ignition performance and long wear in secondary ignition service.
