Astemo ignition coil IGC0056 for Honda & Acura — OEM replacement, durable high-voltage

The Astemo Hitachi IGC0056 ignition coil is a vehicle-specific OEM-quality coil designed to deliver reliable spark energy for compatible Honda and Acura engines.

This ignition coil replaces factory units with a design focused on durability, stable high-voltage output, and minimal electrical interference. Built to OE standards by Astemo/Hitachi, the IGC0056 combines high turns ratios, welded electronic connections and internal protection to maintain consistent performance across varied driving conditions.

How does the IGC0056 improve engine reliability?

The IGC0056 supplies a steady, high-voltage spark to each cylinder, reducing misfires and maintaining smooth combustion under load. Its robust materials and protected circuitry resist heat and vibration, helping the coil keep operating within specs over time.

• High turns ratio produces increased voltage for consistent ignition.
• Welded electronic connection points resist loosening and corrosion.
• Internal capacitor reduces electrical noise for stable ECU signals.
• OEM-level materials minimize deformation under thermal stress.

Which vehicles does this ignition coil fit?

The IGC0056 is a vehicle-specific replacement designed for several Honda and Acura models across late 2000s and early 2010s model years. Always verify fitment by VIN or OEM part cross-reference before purchase.

• Honda Crosstour — 2012
• Honda Accord / Accord Crosstour — 2008–2012 (model-dependent)
• Acura TSX — 2010–2014
• Acura TL — 2009–2014
• Acura RL — 2009–2012
• Honda Odyssey — 2008–2017

What installation and maintenance points should I know?

Installation is similar to other coil-on-plug units: remove the engine cover (if present), unplug the electrical connector, unbolt the coil, and replace with the new unit. Tighten to manufacturer torque, and inspect plug boots and spark plugs while servicing.

• Recommended to replace one coil at a time to confirm issue resolution.
• Check and replace spark plugs if worn or carbon-fouled.
• Use correct torque values and ensure connector clicks firmly into place.
• Observe proper orientation; this is a vehicle-specific fit.

How does this part compare to other aftermarket coils?

The Astemo Hitachi IGC0056 emphasizes OEM compatibility and durable construction rather than lowest cost. It includes design elements—welded connectors, internal noise suppression, and high-quality materials—that align with factory standards, offering a closer match to original performance.

• OE-grade materials reduce the chance of warping or failure under heat.
• Protected circuitry and internal capacitor limit interference with sensors.
• Vehicle-specific engineering ensures fit and electrical compatibility.
• Often preferred for longevity compared with budget aftermarket units.

Who is this for? The Astemo Hitachi IGC0056 ignition coil is for owners and technicians seeking a direct-fit replacement for affected Honda and Acura models who value OE-level reliability and prefer parts engineered to the original specifications. It's appropriate for routine maintenance, troubleshooting misfires, or restoring engine performance in vehicles that list this part as the correct replacement.
