Key Features

• Platinum fine-wire center electrode for focused spark delivery
• Platinum pad ground electrode for extended wear resistance
• Heat-Active alloy helps maintain consistent operating characteristics
• Resistor design for ignition system noise control
• Flat seat design with 14 mm thread diameter and 0.75 in reach
• Pre-gapped at 0.040 in for common service applications
• Champion Double Platinum classification for long-life service use

Product Line Details

Champion Double Platinum Power is the brand’s platinum-on-platinum spark plug line for vehicles that benefit from durable electrodes and stable spark concentration. The design focuses on maintaining ignition performance over time, making it a practical choice for routine tune-ups on vehicles such as the Lexus RX330, Volkswagen Touareg, and Dodge Ram 1500.

Detailed Description

Champion 7436 is a Double Platinum spark plug engineered with a platinum center electrode tip and a platinum pad ground electrode. That construction helps reduce electrode wear while supporting a consistent spark pattern. The plug also features a non-removable nut terminal, hex design, and resistor configuration, with a 0.625 in hex size and 10 heat range. For service work, the 0.040 in pre-gap provides a ready-to-install baseline for many listed applications, though vehicle-specific gap verification is still recommended before installation.

This part cross-references Champion Spark Plug 18 for the same application.

Common Issues This Plug Can Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from inconsistent ignition firing
• Misfire concerns related to aged plugs
• Reduced throttle response from weak spark delivery
• Service intervals overdue on OE-style ignition maintenance

Installation Notes and Tips

• Verify the required gap for your exact year, make, and model before installation.
• Confirm thread diameter, reach, seat type, and terminal style match the original plug.
• Inspect ignition coils and plug wires during service to avoid repeat misfire symptoms.
• Use proper torque procedures to protect the cylinder head and plug threads.
• Check fitment carefully for vehicles with application-specific notes such as OE type or special gap requirements.
