- Center Electrode Core Material: Platinum for robust durability and corrosion resistance.
- Flexible Gap Options: 0.039, 0.040, 0.044, or 0.052 inches to suit a variety of engines.
- Standard Hex Size: 5/8 inch, compatible with common sockets and tools.
- Insulator Height and Reach: 53 mm insulator height, 17.98 mm reach for secure seating in many cylinders.

Broad vehicle fitment highlights
These plugs are designed to fit a wide array of models from multiple brands, including popular pickups, SUVs, and sedans. You may find compatibility with engines in Buick, Cadillac, Chevrolet, Ford, GMC, Lincoln, Mazda, and beyond. Notable examples include configurations in Buick Enclave and LaCrosse, Cadillac SRX and CTS, Chevrolet Equinox and Malibu, Ford F-150 and Edge, Lincoln MKZ, Mazda 6, and GMC Terrain.
Performance, reliability, and maintenance
Engineered for longevity, the recommended replacement interval commonly targets 80,000 to 100,000 miles, depending on driving conditions and maintenance history. In real-world use, you might notice steadier idle and smoother starts when premium iridium-platinum plugs replace older spark plugs, though results vary by vehicle and usage.
