Product Description

The Mishimoto MMIG-STI-1104 ignition coil set of 4 is a high-quality replacement designed for turbocharged Subaru 2.5-liter engines in WRX, WRX STI, Forester, Legacy, Outback, and Impreza vehicles. These coils deliver reliable spark performance through strong phenolic resin construction and pre-lubricated sealed boots that resist heat, moisture, and debris. They refresh the ignition system, improving engine start-up behavior and smoothness, which is especially beneficial when stock coils wear out or begin misfiring under load.

Whether you're maintaining a daily driver or prepping a performance build, these coils restore dependable spark delivery and are backed by Mishimoto's lifetime limited warranty for long-term confidence.
