Description

Fire a more focused spark in your Ford F-150 spark plug replacement job with the Autolite XP26 Iridium XP Spark Plug. It's a direct-fit ignition upgrade for the listed applications — including the 1976 and 1980 Ford F-150 (V8-5.0L/5.8L) plus hundreds of Buick, Chevrolet, Chrysler and other engines across 846 total applications (see the Buyer's Guide tab for the full list).

Iridium fine-wire center electrode: the iridium-enhanced tip with a copper core is designed to increase ignitability and deliver a more focused ignition for improved engine performance.
Platinum taper-cut ground electrode: the proprietary platinum ground with a nickel core adds wear resistance for extended plug life, and the tapered ground wire is designed to improve ignitability.
High-alumina multi-rib ceramic insulator: provides thermal conductivity and strong insulation while helping prevent flash-over.
Nickel-plated shell: corrosion resistant for added durability.

Specs: heat range 7, 14 mm thread (M14-1.25), 5/8 in hex, tapered seat, non-removable nut terminal and a built-in resistor (4000 ohm). Washers are not included. Quantity varies by engine (many applications use 8); this listing is sold individually — order the count your engine requires. Backed by Autolite's lifetime limited warranty. Country of origin: Mexico.
