Product Details

The phenolic resin frame of these Mishimoto ignition coils is built to last, even in high-temperature engine bays. If your Subaru WRX STI is experiencing misfires, especially under boost, or you're just looking to refresh an aging ignition system, these coils are a solid choice. They're designed to meet or exceed the performance standards set by Subaru's factory parts, making them a reliable replacement for worn-out coils.

When you install a fresh set of these coils along with new spark plugs, you can expect a noticeable difference. Your engine should start up more easily, the idle will smooth out, and you'll get back the performance you might have lost. The lower boot on each coil is designed to seal out moisture, preventing contamination in the spark plug wells, and they come pre-lubricated with dielectric grease to ensure a good connection and prevent corrosion.

These coils are a great way to get your EJ engine back to its best, especially if you're planning on adding more power down the road. It's always smart to ensure your ignition system is in top shape before pushing the limits with modifications.
