Parts for your 2020 Subaru Impreza-Ignition coils

Ignition Coils on the 2020 Subaru Impreza: What You Need to Know

The 2020 Subaru Impreza is a popular choice among Aussie drivers thanks to its reliability, all-wheel drive, and efficient performance. Like many modern vehicles, the Impreza uses ignition coils as an essential part of its engine ignition system. So, what exactly are ignition coils, and why are they important for the 2020 Subaru Impreza? Let's take a closer look.

Ignition coils are a crucial component in petrol engines, including the Subaru Impreza's boxer engine found in the 2020 model. Their main role is to convert the car battery's low voltage into the thousands of volts needed to produce an electric spark in the spark plugs. This spark ignites the air-fuel mixture inside the engine's cylinders, which powers the car. Without ignition coils, the engine simply won't start or run efficiently.

On the 2020 Subaru Impreza, each cylinder typically has its own ignition coil mounted directly on top of the spark plug. This design is often referred to as coil-on-plug (COP) ignition, which improves ignition efficiency and reduces energy loss compared to older systems that used a single coil connected by spark plug wires. Having a coil for each cylinder allows for precise control of spark timing and a more reliable ignition process.

Because ignition coils are constantly subjected to heat, vibration, and electrical stress under the bonnet, they can wear out or fail over time. Symptoms of faulty ignition coils in the 2020 Impreza include rough idling, engine misfires, poor acceleration, reduced fuel efficiency, and the illumination of the check engine light. If left unchecked, a failed coil can cause damage to other engine components or lead to costly repairs.

Routine maintenance is key to keeping your Subaru Impreza's ignition system in tip-top shape. While ignition coils don't have a specific replacement interval like spark plugs or oil filters, they should be checked during regular servicing. Mechanics will usually run diagnostic scans to detect any misfires or coil performance issues. It's also wise to visually inspect the coils for signs of cracks, carbon tracking, or corrosion that might indicate they're on the way out.

When it comes time to replace ignition coils on the 2020 Subaru Impreza, it's best to replace all coils at the same time, even if only one seems faulty. Replacing coils in pairs or individually can lead to uneven performance and potential future failures. Genuine Subaru ignition coils are readily available and designed specifically for the Impreza's engine, ensuring durability and reliable operation.

Installing new ignition coils is generally straightforward. Each coil is unplugged from its electrical connector and removed from the spark plug well. The new coil is fitted in its place and connected back to the car's wiring harness. However, it's a task best left to experienced mechanics or DIYers with the right tools and know-how, as improper installation can lead to misfires or damage to the plugs and engine.

Aside from replacement, keeping ignition coils in good shape involves maintaining the overall ignition system. This includes regularly changing spark plugs at the recommended service intervals and keeping the engine bay clean to prevent dirt and moisture from affecting coil performance. High-quality fuel and proper engine tuning also help reduce stress on ignition components.

In a nutshell, ignition coils are absolutely relevant for the 2020 Subaru Impreza and play a vital role in the car's engine starting and running smoothly. Paying attention to their condition as part of your vehicle's servicing routine can save you headaches down the track and keep your Impreza firing on all cylinders. Whether you're cruising along the Great Ocean Road or commuting in the city, healthy ignition coils mean better engine performance, improved fuel economy, and fewer unexpected breakdowns.

So next time you give your Subaru a service, have a chat with your mechanic about the state of those ignition coils. They might just spot an early warning sign and recommend replacing them before a fault puts a dampener on your drive. After all, it's better to be safe and enjoy the open road with confidence.
