Delphi draws on more than a century of OE experience, and that background is reflected in the design and application coverage of this replacement coil. The GN10235 part number is useful when cross-checking service records, catalog listings, or interchange references during diagnosis and repair.

What This Ignition Coil Helps Address

• Engine misfire codes related to weak or inconsistent spark
• Rough idle during cold start or under load
• Hesitation, stumble, or poor throttle response
• Hard starting caused by ignition coil failure
• Intermittent ignition performance on coil-on-plug systems

Installation Notes and Tips

Verify the vehicle’s engine serial number notes before ordering for 2006 Mercedes-Benz applications, since some listings apply only within specific serial-number ranges. Confirm the coil-on-plug layout, boot requirement, and terminal style before installation. Inspect the spark plug, boot, and connector condition during service, and replace any worn components that could affect ignition performance. Use the instruction sheet included with the part for application-specific guidance.

Quality Assurance

Delphi builds this ignition coil using OE-focused knowledge developed through long-term supplier experience with major automakers. The GN10235 is engineered as an aftermarket replacement that follows the application and connection requirements listed in the catalog.
