Description

The Ford Performance M-12259-R462 spark plug wire set is engineered to enhance the ignition system performance of Ford 4.6L 2V Modular engines. These 9mm wires are designed with a spiral-wound suppression core, which significantly reduces resistance and minimizes potential spark loss, ensuring a stronger spark at the plug. The construction utilizes tough silicone insulation and boots, capable of withstanding high operating temperatures and resisting damage from common automotive fluids like fuels, oils, and solvents. This robust build helps prevent voltage loss and crossfire, leading to more consistent engine operation. The set includes 45-degree plug boots for most applications, stainless steel terminals for the distributor cap, and a coil wire if your application requires it. Each wire is clearly numbered to correspond with the correct cylinder, simplifying the installation process. Specifically designed for Ford 4.6L 2-valve engines, this set is a direct replacement or upgrade for applications such as the Mustang. The vibrant red color adds a visual distinction under the hood.
