Ignition Coils on the 2018 Subaru Outback: What They Do and How to Keep Them in Top Shape

The 2018 Subaru Outback is a reliable and popular SUV, well known for its ruggedness and all-weather performance. Under the bonnet, its engine system depends heavily on ignition coils to keep things running smoothly. So, are ignition coils fitted to the 2018 Subaru Outback? Yes, definitely. The 2018 Outback uses ignition coils as a vital component of its ignition system, which is critical to engine performance, fuel efficiency and overall reliability.

Ignition coils are essentially the heart of the spark generation process in petrol engines. In the 2018 Subaru Outback, these coils convert the low voltage from the battery into the high voltage needed to create a spark in the spark plugs. This spark ignites the air-fuel mixture inside the cylinders, powering the engine and keeping it running. Without ignition coils, the engine simply would not start or run properly.

Each cylinder in the Outback's engine typically has a dedicated ignition coil, often called coil-on-plug, which sits directly on top of the spark plug. This design eliminates the need for spark plug wires, improving reliability and ensuring a stronger, more precise spark. For owners, this means a smoother idle, better acceleration and improved fuel economy.

When it comes to maintenance and replacement, ignition coils are usually quite durable. However, over time, wear and tear or exposure to heat and moisture can cause them to fail. Signs that the ignition coils may need attention include engine misfires, rough idling, reduced power and, sometimes, the check engine light illuminating on the dashboard. If these symptoms appear, it is a good idea to have the ignition coils inspected as part of a servicing routine.

Replacing ignition coils on the 2018 Subaru Outback is generally straightforward due to the coil-on-plug setup. Each coil is held in place with just a few bolts and an electrical connector. It is important to use genuine or high-quality replacement coils to avoid further engine issues. When replacing one coil, many mechanics also recommend inspecting the others to ensure consistent performance across all cylinders.

Routine servicing of the ignition coils can help extend their life. Keeping the engine clean underneath the bonnet, avoiding moisture build-up and ensuring the electrical connections remain secure are helpful tips. Some owners may choose to inspect the ignition coils more frequently if the Outback is driven in extreme conditions, like dusty tracks or very wet environments.

Ignoring ignition coil issues can lead to more serious engine problems, such as catalytic converter damage due to unburnt fuel and increased emissions, which may also cause the vehicle to fail emissions testing. Therefore, paying attention to your Outback's ignition system is not just about performance but also about maintaining the vehicle's longevity and environmental compliance.

In terms of longevity, original ignition coils on the 2018 Outback can often last well over 100,000 kilometres if properly cared for. But, like many automotive parts, mileage and driving conditions affect their lifespan. Keeping an eye out for subtle changes in engine behaviour and responding quickly to warning signs helps avoid unexpected breakdowns and costly repairs.

Overall, the ignition coil plays an unassuming yet crucial role in the 2018 Subaru Outback's operation. By ensuring a reliable spark, these coils keep the engine firing in all sorts of driving conditions, whether cruising the highway or tackling off-road trails. With basic awareness of ignition coil health and some routine checks, Outback owners can enjoy trouble-free driving and continue getting the most out of their vehicle.
