Ignition Coils on the 2020 Subaru XV: What They Are and Why They Matter

The 2020 Subaru XV is a popular compact SUV that blends practicality with a sporty feel, making it a favourite for Aussie drivers who need a versatile vehicle. One part that plays a crucial role in the performance of its engine is the ignition coil. If you're curious about what ignition coils do, whether your Subaru XV has them, and how to look after them, you're in the right spot.

First off, yes, the 2020 Subaru XV does use ignition coils. These components are essential for the proper functioning of your vehicle's petrol engine. So why are ignition coils important? Essentially, the ignition coil's job is to convert the 12-volt power from the battery into the high voltage that's needed to create a spark in the engine's spark plugs. This spark ignites the air-fuel mixture inside the engine cylinders, which then powers your car.

In modern cars like the 2020 Subaru XV, ignition coils are typically positioned directly on top of each spark plug. This setup is often called a "coil-on-plug" system, which improves efficiency and reliability compared to older systems where one coil would serve multiple spark plugs through distributor caps and spark plug wires.

Because the ignition coil is responsible for creating that powerful spark, if it fails or starts to go faulty, a driver might notice a range of issues. These can include rough idling, engine misfires, difficulty starting the car, or even poor fuel economy. Sometimes the check engine light will come on if there is a problem with a coil or one of the associated components.

Maintaining the ignition coils on a 2020 Subaru XV is pretty straightforward but important if you want to keep your vehicle running smoothly. The good news is that ignition coils don't need replacing as often as spark plugs do, but they are not exactly 'fit and forget' parts either. Over time, ignition coils can wear out due to heat, vibration, and electrical stress. If you live in a hot climate or regularly take your car on longer drives, the coils can experience more strain.

As part of regular servicing, your Subaru technician will likely check the ignition system and the condition of the coils, especially if any symptoms suggest there may be a fault. If a coil shows signs of weakness or damage, replacing it can be an effective and relatively low-cost fix compared to bigger engine repairs. In most cases, coil failure will affect just one cylinder, so sometimes just a single coil needs to be replaced rather than all of them. However, some people prefer to replace all coils at once to prevent future issues, although that depends on your budget and advice from the mechanic.

It is also worth noting that when changing the spark plugs, it is a smart move to inspect the ignition coils at the same time since they share the same workspace and are subjected to similar stresses. Keeping both parts in good condition helps maintain engine performance, prevents misfires, and improves fuel efficiency. For owners who enjoy DIY maintenance, ignition coil replacement is not overly complicated, but it's important to use genuine or high-quality aftermarket parts to avoid premature failure or engine troubles.

One more tip for looking after your ignition coils: avoid excessive moisture or oil getting near them. Although coils are designed to work in tough conditions, leaks or engine bay contamination can lead to coil damage. Regularly checking for oil leaks and keeping the engine bay clean helps protect these components.

In short, ignition coils are a small but key piece of the 2020 Subaru XV's petrol engine puzzle. They ensure that the spark plugs get the high voltage they need to ignite the fuel and keep the engine running smooth. Treat them with a bit of care, have them inspected as part of your regular servicing, and you can expect reliable performance for many kilometres to come.
