What Does an Ignition Coil Do?

The ignition coil is a critical component of your vehicle's ignition system that transforms the battery's low voltage (typically 12 volts) into the high voltage (20,000-40,000 volts) required to create a spark at the spark plugs. The coil receives a signal from the ignition module or engine control unit (ECU) and generates a powerful spark at precisely the right moment to ignite the air-fuel mixture in the combustion chamber. A properly functioning ignition coil is essential for reliable starting, smooth engine operation, optimal fuel economy, and reduced emissions.

Why Choose Genuine Bosch Ignition Coils?

Installation Notes

Professional installation is recommended for best results. Ignition coil replacement requires disconnecting the battery, removing the coil connector and mounting hardware, and carefully extracting the old coil. Install the new coil in the reverse order, ensuring all electrical connections are clean and secure. Apply dielectric grease to electrical connections to prevent moisture intrusion. Check for proper engine operation after installation. Consider replacing spark plugs and ignition wires (if applicable) if they show signs of wear or damage, as worn components can cause premature coil failure.
