Overview

This genuine replacement part meets original equipment manufacturing standards for durability and ignition efficiency.
Show original supplier description
These spark plugs are precision-matched to specific engine configurations to help eliminate misfires and reduce fuel consumption compared to degraded original units. This part is compatible with a wide range of vehicles, including the 2021-2025 Ford E-350/E-350 Super Duty with the 7.3L gas engine, the 2011-2019 Ford Edge (3.5L/3.7L), 2011-2023 Ford Explorer (3.5L/3.7L), 2011-2023 Ford F-150 (3.3L/3.5L/3.7L/5.0L), and 2011-2025 Ford Mustang (3.7L/5.0L). It also fits various Super Duty models and the Police Interceptor Utility. Please note that this spark plug is specifically designated for 3.5L engines *without* turbochargers. As a direct-replacement part, it is built to original factory specifications for easy installation. Always verify your vehicle's specific engine and trim requirements, as this part replaces multiple superseded part numbers, including CYFS-12Y-T5, CYFS-O92-FT, CYFS-12F-5X, BR3Z-12405-A, CYFS-12F-5, SP-586, SP-520, and SP-520-X.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
