What It Helps Address
- Hard starting caused by worn or inconsistent spark plugs
- Misfire concerns related to weak ignition output
- Rough idle from degraded electrode condition
- Reduced throttle response in aging ignition systems
- Fuel economy loss tied to incomplete combustion
Installation Notes and Tips
Verify the vehicle application against the listed fitment before installation. Confirm the specified gap is correct for the engine, and inspect ignition wires, coils, and boots before replacing plugs. Use proper spark plug service procedures for tapered-seat applications and torque to the vehicle manufacturer’s specification. For Ford Mustang, Ford Thunderbird, and Mercury Cougar applications, matching the listed year range and notes is important because some vehicles use different OE thread and gap requirements.
Quality Assurance
Autolite designs the Iridium XP line with an iridium-enhanced fine-wire center electrode and a platinum ground electrode to support durability and consistent ignition performance in service. Part number XP5145 is built to the listed specifications for the confirmed Ford, Mercury, and Lincoln applications above.
