The Ignition Coil 4/ Vehicle is a critical engine management component responsible for generating the high-voltage spark required to ignite the air-fuel mixture in your engine’s fourth cylinder. As a precise, cylinder-specific replacement part, it is engineered to restore optimal performance, fuel efficiency, and drivability when the original coil fails. Symptoms of a failing ignition coil in this position often include a noticeable engine misfire, rough idle, loss of power, illuminated check engine light (often with codes P0304 – Cylinder 4 Misfire or related coil circuit codes), and increased fuel consumption.

This direct-fit ignition coil is designed to meet or exceed original equipment specifications, ensuring perfect compatibility with your vehicle’s make, model, and engine. It features robust construction with high-quality materials to withstand extreme under-hood temperatures and electrical loads, delivering consistent high-voltage output. Proper installation of the Ignition Coil 4/ Vehicle is straightforward, typically requiring the replacement of the single coil servicing the fourth cylinder. This targeted repair is a cost-effective solution compared to broader system replacements.

By restoring the precise ignition timing and spark strength for cylinder four, this component directly contributes to smoother engine operation, reliable starts, and lower emissions. It is an essential repair item to address performance issues promptly, preventing potential damage to the catalytic converter and ensuring your vehicle runs as intended. Always verify the correct cylinder numbering for your specific engine configuration prior to installation.
