Product Details
Champion Double Platinum Power is the brand line focused on long-life ignition performance with a platinum-to-platinum electrode design. This spark plug is engineered for vehicles that call for a tapered-seat, high-thread plug and a standard 5/8 in. hex socket. It cross-references Autolite HT0 for the same application. Common fitment includes 2004-2008 Ford F-150, 2005-2008 Ford Expedition, and 2005-2008 Lincoln Navigator applications, along with other listed Ford, Lincoln, and Mercury models.
Common Issues This Part Addresses
- Rough idle caused by worn spark plug electrodes
- Hard starting from weak or inconsistent spark output
- Misfire conditions related to aged ignition components
- Reduced throttle response from degraded plug performance
- Service intervals shortened by standard copper plug wear
Installation Notes and Tips
- Verify engine code, cam cover date, and OE plug specification before installation.
- Confirm the 0.044 in. gap requirement against the vehicle application notes.
- Use a 5/8 in. spark plug socket for the 16 mm hex.
- Inspect coil boots and ignition coils during service, especially on Ford F-150, Ford Explorer, and Ford Mustang applications.
- Follow the vehicle manufacturer’s torque specification for tapered-seat plugs.
