This product line is suitable for vehicles requiring precise ignition components with a flat seat and specific heat range.

Technical Description and Specifications

The Champion Iridium 9800 spark plug incorporates a J gap ground electrode tip design with a single ground electrode made from platinum core material. The center electrode tip is crafted from iridium, known for its high melting point and wear resistance, which contributes to longer service life. The spark plug has a pre-gap size of 0.041 inches (1.05 mm), ensuring proper spark gap for efficient combustion. It features a flat seat type and a reach of 0.75 inches, compatible with specific engine designs. The thread diameter measures 14 mm (0.551 inches), and the plug includes a resistor to minimize electromagnetic interference. The non-removable nut electrical terminal and hex size of 0.625 inches (15.88 mm) facilitate secure installation and removal.

Compatible Vehicles and Applications

Common Issues Addressed by Champion Iridium 9800

• Misfiring or rough idling due to worn spark plugs
• Reduced fuel efficiency from inconsistent ignition
• Difficulty starting the engine in cold conditions
• Engine hesitation or power loss during acceleration
• Electrical interference affecting onboard electronics

Installation Notes and Tips

Before installation, verify the spark plug gap is set to the specified 0.041 inches (1.05 mm). Use a torque wrench to tighten the spark plug to the manufacturer’s recommended torque to avoid damage to the threads or seat. The flat seat design requires proper seating to ensure a secure fit and optimal sealing. The hex size of 0.625 inches (15.88 mm) matches standard spark plug sockets. Avoid over-tightening to prevent thread stripping, especially in aluminum cylinder heads.
