2012 BMW 535 Series DELPHI - GN10571 - Ignition Coil

Delphi ignition coils feature an efficient coil design that delivers an enhanced optimum engine performance. Delphi Technologies has been at the forefront of many of these advancements as a key OE manufacturer. They have developed an advanced magnetic design and modelling capabilities that are second to none. The ignition coils have optimum wire length which means the secondary winding is thinner and much longer than the primary, thus offering the required output needed for the voltage to jump the spark plug gap. The windings on the ignition coils are equally spaced and neatly coiled. This method ensures that every turn of the wire has maximum magnetic power. A specific Epoxy is used to insulate and isolate these wires along with a special vacuum technique to remove air bubbles and imperfections and help prevent internal arcing and shorts.

• Delphi ignition coils are OE designed, engineered and manufactured for smart ignition coils
• For maximum magnetic power, the primary and secondary coils are twisted smooth and firmly
• For maximum efficiency, the coils are wound directly onto a unique steel core
• Smart production techniques help in controlling wire length and maintaining voltage
• Wire coating of superior quality resists flaws that can cause failure
• Features advanced DS diagnostics, including the ability to individually activate coils, test cylinders for spark, modify ignition timing, and adapt coils
