Delphi GN11186 Direct Ignition Coil OE Replacement

The Delphi GN11186 is a direct-fit OE replacement ignition coil engineered to restore proper spark delivery and engine performance. Designed as part of Delphi's comprehensive engine management system, this ignition coil supplies precisely timed high-voltage energy to the spark plug, supporting reliable starts, smooth idle, and optimized fuel efficiency.

Delphi draws on decades of original equipment ignition manufacturing experience to produce aftermarket coils that meet or exceed OE design specifications. Every coil undergoes rigorous endurance testing to ensure it can withstand the harsh thermal, mechanical, and electrical stresses of real-world engine environments.

Key Features:

• Engineered to OE design specifications for a direct-fit, no-modification replacement
• Advanced winding process controls wire length between adjacent windings to maintain consistent voltage and protect insulation integrity
• Electrostatic paint coating delivers uniform coil inductance and prevents lamination separation
• Epoxy vacuum technique minimizes air bubbles for superior insulation quality and reduced risk of energy punch-through failures
• High-quality wire and wire coating resists cracks, pinholes, and imperfections that commonly lead to coil failure
• Designed and endurance tested to resist vibration, temperature extremes, and stress caused by worn spark plugs
• Six weld positions for enhanced structural and electrical integrity

The Delphi GN11186 ignition coil is a dependable choice for restoring consistent combustion performance and keeping the check engine light off. Replace at the first sign of misfires, rough idle, hard starting, or a P030X diagnostic trouble code.
