Mishimoto Replacement Ignition Coil For 02-11 Honda Civic

Replacement ignition coil for 02-11 Honda Civic that restores consistent spark delivery to reduce misfires and improve ignition reliability.

This Mishimoto ignition coil addresses the ignition system's role in delivering spark — one of the four essentials for a properly running engine (fuel, air, compression, and spark). Installing a reliable replacement coil helps ensure the ignition circuit performs as intended so weak spark-related misfires are minimized before any power modifications are attempted.

Engineered by Mishimoto, a brand known for motorsports-grade components, this coil is intended as a direct replacement for worn or failing units on compatible Civic models. Use it as part of routine maintenance to confirm the ignition system is not the limiting factor when diagnosing drivability issues or preparing for performance upgrades.

Why it matters

Maintain ignition integrity: Ensures spark is delivered consistently to each cylinder, reducing erratic combustion and misfire symptoms described in the product overview.

Service-first approach: Replacing aging coils before increasing engine output helps isolate baseline performance and prevents misdiagnosis during turbo upgrades or other modifications.

Mishimoto quality: Backed by a supplier with motorsports experience, the product is positioned for durability and dependability in maintenance and performance-oriented applications.

Recommended as a like-for-like replacement when troubleshooting ignition faults or as a preventative service item on 2002–2011 Honda Civic 4-cylinder engines.
