Delphi GN10233 Ignition Coil

Delphi GN10233 Ignition Coil Overview

The Delphi GN10233 ignition coil is a coil-on-plug replacement built for direct ignition systems on select Ford, Lincoln, and Mercury vehicles. It draws on Delphi’s OE heritage and engineering knowledge to support consistent spark delivery in applications such as the Ford F-150, Ford Mustang, and Lincoln Navigator.

Compatible With 2008-2014 Ford Expedition, 2008-2014 Lincoln Navigator, 2008-2010 Ford Explorer, 2008-2010 Ford Explorer Sport Trac, 2008-2010 Ford F-150, 2008-2010 Ford F-250 Super Duty, 2008-2010 Ford F-350 Super Duty, 2008-2010 Ford Mustang, 2008-2010 Mercury Mountaineer, and 2008 Lincoln Mark LT.

Key Features

• Coil-on-plug ignition coil for direct-mount ignition systems
• Blade terminal design with 2 terminals
• One mount ear for secure installation
• Includes ignition coil and instruction sheet
• OE-focused design backed by Delphi’s aftermarket and original equipment experience

Detailed Description

Delphi GN10233 is an ignition coil engineered for vehicles that use a coil-on-plug setup, where the coil mounts directly to the engine and feeds spark to the plug without a traditional distributor. The blade terminal layout and one-mount-ear design support a straightforward replacement on the listed Ford, Lincoln, and Mercury applications. This part cross-references Standard Ignition FD-509 for the same application.

Use the Delphi GN10233 when servicing ignition systems on the Ford Expedition, Ford F-150, Ford Mustang, and Lincoln Navigator, especially when diagnosing weak spark or ignition-related drivability concerns. The part number GN10233 is also a useful reference when matching OE-style ignition coil replacements across the listed fitments.

What This Part Helps Address

• Engine misfire caused by a failing ignition coil
• Rough idle related to inconsistent spark output
• Hard starting from weak ignition performance
• Loss of power under load from ignition breakdown
• Check engine light conditions tied to coil faults

Installation Notes and Tips

Verify engine application and connector style before installation. This coil uses a blade terminal connection and a one-mount-ear mounting style, so the original coil configuration should be matched closely. Inspect the coil boot, spark plug condition, and related ignition components during service to help prevent repeat failures. For 2008 model-year applications, confirm the vehicle uses the direct ignition coil boot noted in the fitment data.

Quality Assurance

Delphi builds aftermarket parts using knowledge developed through decades of OE supply experience. The GN10233 reflects that OE-based approach for ignition service on select Ford, Lincoln, and Mercury vehicles.
