What this part does

The ignition coil is responsible for converting the low-voltage current from the electrical system into the high voltage needed to bridge the gap on a spark plug. This specific component utilizes a direct-ignition, coil-on-plug design, meaning it mounts straight into the spark plug well on the cylinder head without the need for high-tension wires. The engine control unit triggers the coil to fire at the precise moment required for optimal fuel combustion. A failing coil typically results in dedicated cylinder misfires, a rough idle, noticeable power loss under acceleration, and a flashing or solid check engine light.

Before you order

It is heavily recommended to inspect or replace the spark plug when installing a replacement ignition coil. An excessive spark plug gap from normal wear places heavy electrical strain on the coil and is a primary cause of premature failure. While a single faulty coil can be replaced to resolve an isolated cylinder misfire, replacing coils in complete sets is standard practice on higher-mileage engines to maintain balanced ignition performance and prevent subsequent failures.
