Detailed Description

The Delphi GN10446 ignition coil is engineered for vehicles that use a coil-on-plug ignition system, where each coil mounts directly to the spark plug for precise spark control. Delphi draws on OE heritage and supplier experience to build aftermarket ignition parts with the fit and electrical design expected in service replacement. This part number, GN10446, is listed across multiple Audi, Porsche, and Volkswagen platforms, including 2005-2018 Audi A4, A6, A7, A8, Q5, Q7, S4, S5, SQ5, S6, S8, and R8 applications, plus 2007-2015 Volkswagen Touareg and 2011-2018 Porsche Cayenne coverage.

This part cross-references Standard Ignition UF-529 for the same application.

What It Helps Fix

• Engine misfire caused by a weak or failing ignition coil
• Rough idle during cold start or under load
• Hard starting related to inconsistent spark output
• Loss of acceleration response from ignition breakdown
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the coil connector style before installation: this unit uses a 4-pin male terminal layout. Confirm vehicle-specific fitment by year, make, and model, especially on Audi A6 Quattro and A7 Quattro applications with production-date notes in the catalog data. Inspect the spark plug well, connector, and surrounding ignition components before installing the new coil to help prevent repeat failures.

Quality Assurance

Delphi builds this ignition coil using OE experience and original-equipment supplier knowledge carried into its aftermarket line. The GN10446 is intended to meet the electrical and fitment expectations of the listed Audi, Porsche, and Volkswagen applications.
