What are the symptoms of a failing ignition coil?

Common signs of a failing ignition coil include engine misfires, rough idling, reduced engine power, poor fuel economy, and sometimes a check engine light. If you notice these issues, replacing the coils can often resolve them.

Do I need to replace all ignition coils at once?

While you can replace individual coils as they fail, it's often recommended to replace them in sets, especially if they are all original. This ensures consistent performance across all cylinders and can prevent another coil from failing shortly after the first.

What is the warranty on this ignition coil?

This Mishimoto ignition coil is backed by Mishimoto's signature Lifetime Warranty, offering peace of mind with your purchase.

Product Details

When your engine needs a strong spark to run right, a healthy ignition coil is key. This Mishimoto ignition coil is built to meet or exceed the original BMW performance standards for your 4.4L engine. It's a direct replacement for worn or defective factory coils, helping to ensure your engine gets the spark it needs for reliable operation.

A weak spark can lead to all sorts of issues, from rough idling and poor gas mileage to potential damage to your catalytic converter.

It's a smart step to take before considering more significant power upgrades, ensuring your base engine systems are in top shape.
