• 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. Designed and manufactured to operate reliably under all operating conditions and throughout the entire engine speed range for peak engine spark performance
• Ignition Coils generate the spark for your vehicle's engine. However, ignition coils would fail due to age, overuse, or simply manufacture defects. A failing ignition coil may result in misfires, rough idle, reduced fuel efficiency, and the appearance of the check engine light. Therefore, it is important to replace your ignition coils as soon as your car starts showing these symptoms to improve the efficiency and drivability of your vehicle
