Delphi GN10381 Ignition Coil

Delphi GN10381 Ignition Coil Overview

The Delphi GN10381 ignition coil is a coil-on-plug replacement built for Mercedes-Benz applications that need direct spark delivery and reliable electrical connection. It draws on Delphi’s OE heritage and aftermarket engineering to support consistent ignition performance in compatible vehicles.

• Coil-on-plug ignition design for direct spark delivery
• Pin-style terminal with 1 male terminal
• Includes ignition coil and instruction sheet
• Built from Delphi OE experience and supplier knowledge
• Compatible with select Mercedes-Benz C230, SLK230, S320, C280, C36 AMG, E320, SL320, 300CE, 300E, and 300TE applications

Fitment and Application Details

Compatible With 1997-2000 Mercedes-Benz C230, 1998-2000 Mercedes-Benz SLK230, 1994-1999 Mercedes-Benz S320, 1994-1997 Mercedes-Benz C280, 1995-1997 Mercedes-Benz C36 AMG, 1994-1997 Mercedes-Benz E320, 1994-1997 Mercedes-Benz SL320, 1993 Mercedes-Benz 300CE, 1993 Mercedes-Benz 300E, and 1993 Mercedes-Benz 300TE. The Delphi GN10381 is also cross-referenced to Bosch 0221506002 for the same application.

This ignition coil is used to restore proper spark output when the original coil begins to weaken or fail. It is a direct-fit style replacement for Mercedes-Benz ignition systems that use a coil-on-plug configuration and a pin terminal connection.

Common Issues This Part Addresses

• Engine misfire under load or at idle
• Hard starting caused by weak ignition output
• Rough running from inconsistent spark delivery
• Check engine light related to ignition coil faults
• Loss of acceleration response from degraded coil performance

Installation Notes and Tips

Verify the connector style, terminal layout, and vehicle application before installation. Inspect the spark plug, boot, and surrounding ignition components at the same time, since worn plugs or damaged boots can affect coil performance. Follow the included instruction sheet and confirm all electrical connections are fully seated.

Quality Assurance

Delphi builds this ignition coil using OE-focused engineering informed by more than a century of original equipment experience and supplier knowledge. That background is reflected in the design and application coverage of the GN10381.
