Ignition Coil, Set of 4, fits Subaru WRX/STi 2.5L 2011-2021 - Mishimoto - MMIG-STI-1104

The basic requirements for a properly running engine are fuel air compression and spark. Before cranking up the boost in your flat four it is wise to ensure all maintenance is up to date and these processes are performing as intended. Weak spark from your ignition system can result in misfiring under high load driving and spark blow-out under high boost which is bad for performance. Mishimoto is proud to launch our new lineup of ignition coils aimed at providing a high-quality replacement that can bring your vehicle up to Stage 0 before moving on to horsepower adding modifications. Our ignition coils are designed and tested to meet or exceed OEM Subaru performance standards and are available as a single coil or in sets of four. Once installed with a set of new spark plugs one can expect a refreshed ignition system with improved engine startup a smoother idle and restored performance from your EJ. The primary frame of our coils is constructed from extremely robust phenolic resin ensuring optimal longevity in high temperature environments. The precision lower boot provides a barrier against moisture entry into the plug well eliminating chances for spark plug contamination. In addition our coils are pre-lubricated with dielectric grease to prevent corrosion and ensure an optimal connection between the spark plug and coil. Mishimoto ignition coils are an ideal replacement for worn or defective factory coils. As with all our products these ignition coils include our signature Mishimoto Lifetime Warranty.
