Product Details

Champion Platinum Power 3066 is a replacement spark plug for vehicles that call for plug type RS7PYB5. The platinum tip and focused electrode design help maintain a sharp spark path, while the resistor construction supports stable ignition system operation. This part cross-references AGSF22FCM and SP479 for the same application. It fits 2005-2006 Ford GT, 2004 Ford F-150 Heritage, 2000-2003 Ford F-150, 1999 Ford F-150, and 1999 Mazda B3000, making it a direct-match option for owners searching for a Ford F-150 spark plug or Ford GT spark plug replacement.

What It Is Used For

  • Replacing worn spark plugs that can cause rough idle
  • Restoring consistent ignition in hard-start conditions
  • Addressing misfire symptoms tied to plug wear
  • Maintaining proper combustion in high-mileage tune-ups
  • Servicing Ford F-150, Ford GT, and Mazda B3000 ignition systems

Installation Notes and Tips

Verify plug type RS7PYB5 and confirm the specified 0.044 in gap for the listed vehicle applications before installation. Check thread diameter, reach, and seat type against the original plug to ensure proper fitment. Use the vehicle manufacturer’s torque specification and inspect ignition wires or coils during service to avoid repeat misfire concerns.
