Astemo Hitachi IGC0056 ignition coil for Honda & Acura — OE-fit, heat-resistant, reduces misfires

Astemo’s Hitachi IGC0056 ignition coil is a vehicle-specific, OE-grade coil built to deliver consistent high-voltage spark energy for compatible Honda and Acura engines.

This ignition coil is engineered to replace factory units without modification, supplying the voltage and durability modern high-compression engines require. Constructed with heat-resistant materials, a high turns ratio, and protected circuitry, the IGC0056 aims to restore smooth running, reduce misfires, and maintain fuel efficiency when installed as a like-for-like replacement. Connections are welded and internal components include a capacitor to limit electrical noise, matching the quality expected from original-equipment suppliers.

How does the IGC0056 improve engine performance?

By reliably converting battery voltage into the high-voltage pulse needed for spark plugs, this coil supports efficient combustion and steady engine operation. Replacing a failing coil with the IGC0056 helps eliminate misfires and hesitation that can affect driveability.

• High turns ratio for increased voltage output to spark plugs
• Internal capacitor reduces electrical interference with engine electronics
• Welded electronic connection points for consistent conductivity through heat cycles

What vehicles and fitment does the IGC0056 support?

The IGC0056 is manufactured to match specific OEM fitment specifications so it installs like the original part. Check vehicle year and model compatibility before purchase to confirm fitment for your application.

• Fits Honda Crosstour (2012) and Honda Accord Crosstour (2010–2011)
• Compatible with Acura TSX (2010–2014), Acura TL (2009–2014), Acura RL (2009–2012)
• Also fits Honda Odyssey (2008–2017) and Honda Accord (2008–2012)

What build features ensure durability and reliability?

The IGC0056 uses materials and assembly methods intended to withstand high under-hood temperatures and repeated electrical stress. These design choices reduce the chance of deformation or premature failure when compared with lower-grade aftermarket coils.

• High-quality insulators and thermal-resistant housing to resist heat damage
• Protected internal circuitry to minimize failure from vibration and contamination
• New original equipment part standard—meets OE supplier criteria for performance

How easy is installation and what should I expect after fitting one?

Installation is straightforward for anyone familiar with basic ignition system work because the coil is vehicle-specific and matches the factory mounting and electrical connector. After installation you should notice steadier idle, fewer misfires, and restored throttle response if a faulty coil was the issue.

• Direct-fit replacement—no modifications required for compatible models
• Standard electrical connector and mounting points align with OE locations
• Typically resolves coil-related trouble codes and drivability symptoms

Who is this for? The Astemo Hitachi IGC0056 ignition coil is aimed at owners and technicians working on compatible Honda and Acura vehicles who need an OE-quality replacement. It’s appropriate for drivers addressing misfire codes, rough idling, poor throttle response, or anyone restoring original ignition performance. If you require a direct-fit, high-durability coil built to the specifications of original-equipment suppliers, the IGC0056 is engineered to meet those needs.
