Product Description

The **Ford Performance M-12405-50VDE Cold Spark Plug Set** is a factory-engineered replacement set of eight high-performance spark plugs designed specifically for the **2021-2025 Ford F-150** equipped with the **5.0L Coyote V8 featuring Variable Displacement Ti-VCT**. These plugs feature a **colder heat range (HR8)** that helps resist pre-ignition and detonation under high-load or boosted conditions, making them ideal for performance-tuned or forced-induction engines where combustion stability is critical.

Each plug is built to direct OEM specifications using a 12 mm thread design for a precise fit into the factory cylinder head. Sold as a full set of eight, this kit delivers a balanced upgrade across all cylinders and is recommended for drivers seeking improved ignition performance. A **spark plug gap around 0.032"** is recommended, especially in supercharged or high-stress scenarios, to ensure optimal combustion and throttle response. Notably, this plug set **does not fit Mustang Coyote engines** - it is intended solely for the specified F-150 application.
