Premium Quality Material - You'll have an easy time mounting these coils due to their lightweight and winding construction. The copper material ensures maximum power delivery to the spark plugs. They come pre-greased for direct replacement.Superior winding process yields greater wire length control, which means less chance of a breakdown of the wire coating and insulation. Material resists pinholes and cracks that can cause failures.. Function & OEM Fit - OCPTY Ignition Coils are engineered for original equipment and replacement applications.Every component either matches or improves on the OE design to ensure fast and easy installation with superior performance and reliability.The ignition coil acts like a transformer.the ignition coil transforms the electrical energy from the vehicle battery into high voltage, saves it briefly and then emits it as a high voltage current pulse to the spark plug..
