Delphi GN10237 Ignition Coil Pencil Coil-on-Plug

The Delphi GN10237 is a pencil-style ignition coil engineered to Original Equipment specifications for reliable engine performance. This coil-on-plug design mounts directly onto the spark plug, delivering precise spark timing and optimized fuel efficiency with no moving parts and high-RPM capability.

Advanced Engineering Features:

• High-quality wire construction with specialized coating that resists cracks, pin holes and imperfections
• Epoxy vacuum technique reduces air bubbles to increase insulation quality and prevent energy punch-through failures
• Controlled winding process reduces voltage differences between adjacent windings for improved durability
• Electrostatic paint coating ensures consistent coil inductance and prevents lamination separation
• Corona-resistant case fully encapsulates the coil and integral igniter module in one compact package
• Designed and endurance tested to withstand vibration, temperature changes and common stresses that cause failure

Delphi manufactures over 10 million ignition coils annually for North America, each built with OE expertise gained from over 100 years as a supplier to the world's leading automakers. This proven design helps ensure fast starts, consistent engine performance, and improved emissions control.
