Technical Details of Champion 7346 Spark Plug

This spark plug features a platinum ground electrode core and a platinum center electrode tip, providing a stable and long-lasting spark. The ground electrode has a single platinum pad surface, which helps maintain consistent ignition over time. The insulator height and projection are both 0.06 inches, supporting proper spark gap and insulation. The center electrode diameter measures 0.1 inch, contributing to efficient combustion. The plug type is Rc10pyp4, with a flat seat and a taper diameter of 0.27 inches, ensuring compatibility with specified engine designs.

About the Double Platinum Power Product Line

The Double Platinum Power line from Champion is designed to offer enhanced ignition reliability by utilizing platinum on both the center and ground electrodes. This dual platinum design reduces electrode wear and maintains a consistent spark gap longer than conventional plugs. The 7346 spark plug benefits from this technology, making it suitable for vehicles requiring stable ignition performance under various driving conditions.

Compatible Vehicles and Applications

This spark plug is compatible with a variety of makes and models, including but not limited to Acura Integra, Ford Probe, Toyota Supra, Subaru Impreza, and Nissan 300ZX. It is ideal for vehicles that require a 14 mm thread diameter and a heat range of 10.

• Resolves misfires and rough idling issues
• Improves cold start performance
• Reduces spark plug fouling and electrode wear
• Enhances fuel efficiency by ensuring complete combustion
• Minimizes electrical interference with onboard electronics

Installation Notes and Tips

Before installation, verify the spark plug gap is set to 0.041 inches (1.05 mm) as pre-gapped. Use a 15.88 mm (0.625 inch) hex socket for proper torque application. Ensure the spark plug is threaded by hand initially to avoid cross-threading. The flat seat design requires proper seating torque to maintain a secure fit and optimal sealing. The non-removable nut terminal ensures a stable electrical connection but requires compatible ignition wires or boots.

Quality Assurance and Warranty

Champion spark plugs are manufactured to meet strict OEM specifications. The Double Platinum Power 7346 spark plug includes a resistor to reduce radio frequency interference, supporting vehicle electronics. While specific warranty details vary by distributor, Champion products typically come with a limited warranty against manufacturing defects. Always consult vehicle service manuals for proper installation and maintenance guidelines.
