Delphi ignition coils feature precise spark timing response for increased fuel economy and faster crank-to-run. The ignition coils provide accurate electrical energy to create a voltage potential at the spark plug, providing for superior engine performance that adjusts to driving and environment conditions. Plus, like all Delphi ignition system components, they enable engine management systems to maintain tighter control over emissions, economy and performance.

Product Features:

• Improved dwell accuracy decreases module and coil temperatures for greater reliability
• Noise abatement material between laminations reduces audible coil noise
• Cassettes have improved primary connector for greater ease of assembly compared to designs with one connector for each coil
• Lower primary inductance provides high-speed performance
• Early and precise electronic spark timing helps improve fuel economy and provides faster crank-to-run
• Higher energy delivered to combustible mixture provides cleaner combustion to help manufacturers meet on-board diagnostics (OBD II) requirements
• Direct connection to spark plugs (via small boot) eliminates spark plug wires
• Composite iron coils provide programmable energy
• Coil per cylinder dwell overlap electronics deliver better high speed performance and better heat dissipation compared to some conventional technologies
• Coil per cylinder ramp and fire electronics decrease power dissipation and increase efficiency
• Radio frequency interference (RFI)suppressor optional

Every WSO ignition coil is developed and designed for its specific application, and engineered for maximum performance. WORLD SOURCEONE ignition coils are designed to operate reliably and dependably under all operating conditions and engine rpm ranges, providing the highest engine performance, low exhaust emissions, and fuel economy objectives. WSO Direct Ignition Coils are designed to adapt the required energy output to match engine-operating conditions and deliver the optimum energy level needed to ignite a diluted stratified charge.

Product Features:

• OE-Equivalent and a direct fit application
• Superior, reliable performance compared to competitive products
• Lower cost alternative to original equipment
• No additional time consuming steps needed for installation
• Factory original equipment connectors
• Improved coil efficiency reduces the need to generate excessive high voltage

Delphi OE technology ignition products are validated to match the vehicles system; OE quality replacement parts for the right fit , form and function; Delphi coils provide OE performance, durability and electromagnetic capacity level requirements.

Product Features:

• Delphi coils provide OE performance, durability and electromagnetic capacity level requirements
• Delphi ignition coils are designed to operate as part of an integral engine management system to insert power into spark plugs and ensure fast starts; consistent engine performance and optimized fuel efficiency
• Delphi uses winding process techniques to control the length of wire between adjacent windings; that’s important since more length means greater voltage differences and can create more pressure that could break down the insulation and wire coating
• We back our ignition coil design with proven materials, such as high quality wires and wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues
