Standard Copper Core Spark Plug Tested to Ford specifications for performance and emissions. Resistant to oxidation and arc erosion. Multi-rib insulator protects against misfire. Service interval of up to 60,000 miles. Nickel-Alloy Spark Plug Feature electrodes engineered for extended life without platinum enhancements. Resistant to oxidation and arc erosion. Multi-rib insulator protects against misfire. Nickel-plated shell for corrosion resistance. Service interval of up to 60,000 miles. Non-Extended-Tip Spark Plug Used in most older-model car engines and some current-model truck engines. Commercial and small engine applications. Extended-Tip Spark Plug Fits most automotive as well as many specialty applications. Used in most modern engines. Helps prevent fouling at low speeds. Provides self-cleaning action at higher speeds. Extra-Extended-Tip Spark Plug Used in certain specially designed engines. Projects farther into combustion chamber to achieve optimum spark location. Platinum-Tip Spark Plug Used for conventional distributor-equipped and coil-on-plug ignition systems found in many Ford, Lincoln and Mercury vehicles. High melting point provides excellent resistance to erosion. Provides service intervals from 60,000 to 100,000 miles. Available as replacement spark plugs for older model-year vehicles. Designated by the letters P or E in the part number suffix on plug body and box. Resistant to oxidation and arc erosion. Multi-rib insulator protects against misfire. Nickel-plated shell for corrosion resistance. Helps realize extended service intervals of 60,000 to 100,000 miles Fine-Wire Double-Platinum Spark Plug Enhanced electrode wear vs single platinum. 2 to 3 times more platinum vs single platinum reduces the required firing voltage, resulting in diminished erosion of the platinum and increased resistance to fouling. Fits most automotive and many specialty applications. Available as replacement spark plugs for older model-year vehicles. Designated by the letters F or FE in the part number suffix on plug body and box. 0.8 mm fine-wire design. Includes a platinum pad on both electrodes. Proprietary platinum pad on side wire electrode. Nickel-plated shell for corrosion resistance. Service interval of up to 100,000 miles. Platinum-Iridium Spark Plug Can be used in any engine regardless of ignition system. Iridium-enhanced center electrode. Proprietary platinum pad on side wire electrode. 0.8 mm fine-wire design. Resistant to oxidation and arc erosion. Multi-rib insulator protects against misfire. Nickel-plated shell for corrosion resistance. interval of up to 100,000 miles. High-Strength Steel High Thread Spark Plug 0.8 mm fine-wire design. Resistant to oxidation and arc erosion. Multi-rib insulator protects against misfire. Nickel-plated shell for corrosion resistance. Service interval of up to 100,000 miles. Motorcraft Spark Plugs are designed with high quality materials to provide reliable performance for almost any application.
