Delphi GN10519 Pencil Coil-on-Plug Ignition Coil

The Delphi GN10519 is a direct-fit pencil-style coil-on-plug (COP) ignition coil engineered to OE design specifications. As a Tier 1 OE supplier with over 100 years of ignition system experience, Delphi leverages its original equipment heritage to deliver aftermarket parts that meet or exceed factory performance standards.

Pencil coils mount directly on top of each spark plug, replacing traditional multi-cylinder coil packs with a dedicated single-coil design per cylinder. This configuration allows more precise spark timing control on an individual cylinder basis, helping ensure fast starts, consistent engine performance, and optimized fuel efficiency.

Key Features:

• OE-Engineered Design: Manufactured to original equipment specifications for a direct-fit, no-modification replacement
• Corona-Resistant Case: The coil and integral igniter module are fully encapsulated in a corona-resistant housing to protect against electrical leakage
• Advanced Winding Technology: Precision winding process controls wire length between adjacent windings to minimize voltage differences and reduce insulation breakdown risk
• Electrostatic Paint Coating: Ensures consistent coil inductance and prevents lamination separation
• Epoxy Vacuum Process: Reduces air bubbles in the epoxy fill, improving insulation quality and minimizing energy punch-through failures
• High-Quality Wire & Coating: Premium wire and wire coating resist cracks, pinholes, and imperfections that commonly cause coil failures
• 6 Weld Positions: More weld points than many competing designs for superior structural integrity
• Endurance Tested: Designed and tested to resist vibration, thermal cycling, and the stresses caused by related component failures such as worn spark plugs

The Delphi GN10519 pencil coil delivers the reliability and durability expected from a global OE supplier, making it a trusted choice for professional technicians and DIY enthusiasts seeking a quality ignition coil replacement.
