Mishimoto 2011+ Subaru WRX STI Single Ignition Coil

When you're getting your engine running right, a strong spark is just as important as fuel and air. If your Subaru WRX STI is experiencing misfires, especially under load or high boost, a weak ignition coil could be the culprit. This Mishimoto ignition coil is designed to be a direct replacement for your factory unit, bringing your ignition system back to its best before you start adding more power.

This coil is built with a phenolic resin frame, which holds up well in hot engine bay conditions. The boot at the bottom is designed to keep moisture out of the spark plug well, preventing contamination and ensuring a solid connection. Mishimoto tests these coils to meet or exceed the original Subaru performance standards, so you can expect your engine to start up more easily, idle smoother, and get back to its intended performance.

This is sold as a single coil, so you can replace just the one that's gone bad, or pick up a set of four if you want to refresh the whole system. It comes pre-lubricated with dielectric grease to help prevent corrosion and ensure a good electrical connection right out of the box.
