Detailed Product Description

Delphi GN10426 ignition coil is engineered for vehicles that use a coil-on-plug ignition layout, where each coil mounts directly to the spark plug. That design helps maintain reliable spark output and stable ignition performance across the engine speed range. Delphi draws on more than a century of OE experience, and that background is reflected in the fit, connector style, and application coverage of this replacement coil.

This part is listed for 2008-2017 Honda Odyssey, 2009-2015 Honda Pilot, 2009-2014 Honda Ridgeline, 2008-2012 Honda Accord, 2012 Honda Crosstour, 2010-2011 Honda Accord Crosstour, plus Acura RDX, TL, TSX, MDX, ZDX, and RL applications. If you are replacing a failing ignition coil on a Honda Odyssey or Acura TL, GN10426 provides a direct-service option for the specified vehicles.

This part cross-references Beck/Arnley 178-8379 and DENSO Auto Parts 673-2311 for the same application.

Common Issues This Part May Address

• Engine misfire codes related to weak or inconsistent ignition output
• Rough idle or hesitation during acceleration
• Hard starting caused by ignition coil failure
• Loss of power under load from intermittent spark delivery
• Check engine light concerns tied to coil performance

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle application before installation. Inspect the spark plug, coil boot area, and electrical connector for heat damage, corrosion, or oil contamination before fitting the new coil. For best results, replace any worn spark plugs at the same time if service history indicates they are due.
