Delphi GN10441 Pencil Ignition Coil (Coil-on-Plug)

The Delphi GN10441 is a pencil-style coil-on-plug ignition coil engineered to Original Equipment design specifications. Built with over 100 years of OE supplier expertise, this direct-replacement coil delivers the precise spark timing and reliable electrical energy your engine needs for fast starts, consistent performance, and optimized fuel efficiency.

Key Features:

• OE-Matched Design: Engineered to OE specifications for a direct, hassle-free replacement
• Pencil Coil (Coil-on-Plug) Design: Mounts directly on the spark plug for a shorter energy path, improving spark delivery and reducing energy loss
• Smart Winding Process: Precisely controlled wire lengths between adjacent windings help maintain consistent voltage and reduce insulation stress
• Premium Wire Coating: High-quality insulation resists cracks, pinholes, and imperfections that are the most common causes of coil failure
• Epoxy Vacuum Process: Air bubbles are minimized in the epoxy fill, improving insulation quality and reducing the risk of energy punch-through failures
• Endurance Tested: Designed and tested to withstand vibration, heat cycling, and the stresses caused by worn spark plugs or other related component failures
• No Moving Parts: Solid-state pencil coil design provides high-RPM capability with maximum reliability

Delphi manufactures more than 10 million ignition coils annually for the North American market, supplying top automakers including Ford, Toyota, Nissan, GM, Mazda, Chrysler, Subaru, and more. The GN10441 brings that same OE-level performance and durability to the aftermarket.
