MISHIMOTO (2012-2018 Ford Focus ST) (2015-2023 Mustang EcoBoost) Ignition Coil Set

A properly functioning engine depends on fuel, air, compression, and spark. Before increasing boost on your EcoBoost platform, it’s essential to ensure all maintenance is current and the ignition system is performing as intended. Weak spark can lead to misfires under high‑load operation and spark blowout at elevated boost levels, both of which reduce performance and drivability. Mishimoto’s ignition coils are engineered as high‑quality replacements designed to restore the ignition system to optimal condition before pursuing further power‑adding modifications.

Each coil is designed and tested to meet or exceed OEM Ford performance standards and is available individually or as a complete set of four. When installed alongside fresh spark plugs, these coils provide improved engine startup, smoother idle quality, and restored performance. The primary frame is constructed from robust phenolic resin to ensure long‑term durability in high‑temperature environments. A precision‑molded lower boot protects against moisture intrusion in the plug well, preventing contamination. Each coil is pre‑lubricated with dielectric grease to promote corrosion resistance and ensure a secure electrical connection between the coil and spark plug.

Mishimoto ignition coils are an ideal replacement for worn or failing factory units and deliver reliable performance for daily driving, spirited use, and modified EcoBoost applications. As with all Mishimoto components, these ignition coils are backed by the Mishimoto Lifetime Warranty.
