We’ve used over 100 years of OE ignition system experience to create advanced magnetic design and modelling capabilities. The result, an efficient coil design that helps to deliver optimum engine performance, exhaust emissions, and fuel economy. With one of the most comprehensive line of ignition coils and smart ignition systems in the industry, Delphi supplies OE applications for some of the top vehicle manufacturers globally including BMW, GM, Mercedes Benz, Nissan, Peugeot and Volkswagen. In fact, we supply 23 million OE coils per year. That’s a lot of coils!
OE Expertise in the Aftermarket.
We bring the same OE expertise to the aftermarket. In Europe alone, our range includes some 20 OE ignition coils that cover more than 10 million vehicles. That’s backed up by an extensive OE quality all-makes range for optimum coverage, as well as access to OE-level diagnostics, training, technical support and information .
OE technology for optimum creation, transmission, timing and delivery of the ignition spark energy under all operating conditions and throughout entire engine speed.
The continuous development of ignition technology has advanced in recent years – and with it, the requirements from vehicle manufacturers. For this reason, Delphi offers different ignition coil technologies:
Results in fewer materials and tighter coupling to the electromagnetic circuit. This helps deliver energy more efficiently and continuously to enhance engine performance and optimize fuel efficiency.
B- Corona-resistant case
The coil and integral igniter module are fully encapsulated into one package.
C- More Precise Spark Timing Response
For increased engine performance.
D- Direct Placement on the Spark Plug
Gives the spark a shorter distance to reach the spark plug; also the coil placement provides a perfect fit in the plug hole for effective sealing.
> If you notice any damage such as a cracked coil housing, broken anti-rotational tabs or broken connector while assembling coils to the engine, disregard it. A damaged part could result in premature failure and a poorly seated boot could lead to engine misfire.
> Never remove or disassemble the boot from the coil as this could lead to losing the spring and/or suppressor. The result – engine misfires and RFI noise.
> Do not scratch the HV tower or coil housing. A cracked case and/or HV tower could lead to arc thru and coil failure.
> Be careful not to strike any part of the ignition system with a tool or other object. This could induce micro-cracking at the coil HV tower and could deform or damage the plug wire terminal, leading to potential premature failure.
> Don’t apply any non-approved material to the surface of the high voltage tower which mates with the high voltage secondary leads, as this can jeopardize the seal integrity of the mating surfaces, which in turn can create a secondary high voltage leak path and carbon tracking.
> Similarly do not spray material onto the electrical connectors. Insulating-type spray can create a high resistance or open connection. Conductive-type spray can create an electrical short condition.
> Always apply the specified torque to the specified mounting thru-bolt. Loose thru-bolts could lead to failure under vibration. Over-tightened thru-bolts could lead to cracked coil mounting ear and/or premature thru-bolt failure.
> Do not support the ignition system by the wiring harness or plug wire. This can create a poor electrical connection or even become disconnected, allowing the system to fall.
> Never force feed the engine wire harness mating connector into the coil connector. Always ensure the mating connectors are entirely seated and locking mechanism is engaged. A snap should be heard or felt upon a good connection. This maintains a proper connection and prevents intermittent electrical connections leading to an improper ignition system operation.
