Autolite XP24 Iridium Spark Plug Overview
Autolite XP24 is an iridium spark plug built for performance-focused ignition service. It uses an iridium fine-wire center electrode and a platinum ground electrode to support durable spark delivery, efficient combustion, and consistent ignitability across a wide range of Ford, Chevrolet, GMC, Buick, Pontiac, Isuzu, Jeep, Cadillac, and Oldsmobile applications.
The Autolite Iridium Spark Plug line is engineered for drivers who want stable ignition performance with a tapered ground electrode design that helps promote efficient flame travel. If you are replacing worn plugs in a Ford F-150, Chevrolet Camaro, or GMC Sierra-era application, XP24 provides a direct-fit service option for many older domestic and import vehicles.
Key Features
- Iridium-enhanced fine-wire center electrode for precise spark delivery
- Platinum ground electrode for added durability
- Taper-cut ground electrode tip design to support engine efficiency
- Resistor type plug with 4000 resistance
- Copper core center electrode and nickel ground electrode core
- Ceramic insulator for stable high-temperature operation
- M14 x 1.25 thread size, 5/8 hex, tapered seat
- Performance-grade ignition component
Detailed Description
Autolite XP24 is designed around a fine-wire iridium center electrode and a platinum-tipped ground electrode to maintain strong ignition performance under demanding conditions. The tapered ground wire helps improve combustion efficiency, while the resistor design supports cleaner electrical operation in the ignition system. With a mid-projection configuration and tapered seat, this spark plug is built for applications that require the listed OE-style dimensions and heat range 9 specification.

What It Helps Address
- Hard starting caused by worn or eroded spark plug electrodes
- Rough idle from inconsistent ignition firing
- Misfire conditions related to aged plugs
- Reduced throttle response from weak spark delivery
- Fuel economy loss tied to inefficient combustion
Installation Notes and Tips
Verify thread size, seat type, heat range, and gap specification against the vehicle service information before installation. Use the correct torque procedure for tapered-seat plugs and inspect ignition wires, coils, and boots at the same time to avoid repeat misfire concerns. This plug is listed for a broad range of older Ford, Chevrolet, GMC, Buick, Pontiac, Isuzu, Jeep, Cadillac, and Oldsmobile models, including Ford F-150, Chevrolet Camaro, and GMC S15-era applications.
