The lifespan of an ignition coil can vary greatly depending on driving conditions and maintenance. However, they are designed for long-term durability under normal operating circumstances.

This refers to the design of the coil, where it fits snugly and directly into the spark plug well, often referred to as a 'pencil' style coil due to its shape.

This specific coil is designed for a range of model years, with compatibility extending from 2002/2003 up to 2009 for certain vehicle types, depending on the specific model and construction dates.

Check the ignition coil for proper connection. If symptoms persist, the coil may be faulty and require replacement. Ensure all spark plugs are in good condition.

A Check Engine light often indicates an ignition system fault, potentially including a failing ignition coil. Professional diagnosis is recommended to confirm the issue.

A weak spark from a faulty ignition coil can cause power loss. Replacing the coil, along with ensuring other ignition components are functional, should resolve this.

Inefficient combustion due to a faulty ignition coil can lead to increased fuel consumption. Replacing the coil can restore optimal fuel efficiency.
