2004 BMW 325Ci Ignition Coils

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
