Delphi GN10445 Ignition Coil

Delphi GN10445 Ignition Coil Overview

Delphi GN10445 is a coil-on-plug ignition coil built for direct replacement service on select Audi and Volkswagen applications. It uses a pin-style, 4-terminal male connection and includes the ignition coil plus an instruction sheet for service reference.

With OE heritage built from more than a century of original-equipment experience, Delphi applies supplier-level knowledge to aftermarket ignition parts. This ignition coil is a fitment-based replacement for 2002-2004 Volkswagen Passat, 2004-2006 Volkswagen Phaeton, and 2005-2009 Audi A8 Quattro applications.

Key Features

• Coil-on-plug ignition coil for direct spark delivery at the cylinder head
• Pin terminal design with 4 male terminals
• Replacement part number GN10445 for service matching
• Includes ignition coil and instruction sheet
• OE-informed design backed by Delphi’s original-equipment experience

Detailed Description

Delphi GN10445 is an ignition coil engineered for vehicles that use a coil-on-plug setup, where each coil mounts directly to the spark plug. This design supports consistent ignition performance in applications such as the Audi A8 Quattro, Volkswagen Phaeton, and Volkswagen Passat, helping restore proper spark delivery when the original coil shows wear or failure. The part number GN10445 is also useful when cross-checking service records or matching an existing replacement reference.

This part cross-references Bosch 0986221050 for the same application.

What It Helps Address

• Engine misfire caused by a weak or failed ignition coil
• Rough idle related to inconsistent spark output
• Hard starting tied to ignition coil breakdown
• Loss of acceleration response from intermittent coil performance
• Check engine light conditions associated with ignition system faults

Installation Notes and Tips

Verify the vehicle’s year, make, model, and engine-specific ignition coil configuration before ordering. Confirm the connector style, terminal count, and coil-on-plug layout match the original part. Inspect the spark plug well, electrical connector, and surrounding ignition components during replacement, and clear diagnostic trouble codes after installation if required.

Quality Assurance

Delphi draws on OE supplier experience and original-equipment engineering knowledge when producing aftermarket ignition components. GN10445 is built to align with the fitment and connection requirements of the listed Audi and Volkswagen applications.
