Spark Plugs on the 2017 Holden Commodore: What You Need to Know

The 2017 Holden Commodore is a popular car in Australia known for its reliable performance and solid engineering. When it comes to keeping this vehicle running smoothly, one key component to understand is the spark plug. Spark plugs play an essential role in the functioning of petrol engines, including the ones fitted in the 2017 Commodore models. Whether you're a new owner or just curious about how your car works, knowing why spark plugs matter and how to maintain them can save you hassle down the track.

First off, the 2017 Holden Commodore does indeed have spark plugs, assuming we are talking about the petrol variants such as the VF or ZB Commodore with V6 or V8 engines. Spark plugs are a standard part of any petrol engine system because they are responsible for igniting the air-fuel mixture inside the engine's cylinders. If you are driving a diesel variant, however, spark plugs won't be found in the engine since diesel engines use compression ignition rather than spark ignition to start combustion.

For those driving petrol Commodores, the spark plug's job is pretty straightforward but incredibly important. Every time the engine turns over, the spark plug creates a tiny electrical spark that ignites the mixture of air and petrol inside the combustion chamber. This controlled explosion then produces the power needed to get the wheels turning. Without healthy spark plugs, engines can misfire, struggle to start, lose fuel efficiency and even cause increased emissions.

Over time spark plugs wear down and their ability to provide a consistent spark lessens. This happens because the electrode materials in the spark plug erode from repeated sparking and deposit build-up from fuel combustion can coat the plug. In the 2017 Holden Commodore, replacing spark plugs at recommended service intervals is a key part of keeping the car running efficiently and smoothly.

When it comes to maintenance, the official Holden servicing schedule often suggests inspecting and replacing spark plugs roughly every 60,000 to 100,000 kilometres depending on the model and engine type. Modern spark plugs are typically made with long-lasting materials like iridium or platinum which means they don't need to be swapped as often as older copper plugs. Still, it's good practice to check them regularly as part of your routine servicing.

Replacing spark plugs in a 2017 Holden Commodore is usually a straightforward job for a mechanic, but for hands-on owners, it can be a satisfying DIY task. It's important to always use spark plugs that match the vehicle manufacturer's specifications to ensure optimal performance and avoid engine damage. Holden's official parts or quality aftermarket spark plugs designed for the Commodore's engine type will have the right heat range, size and gap settings.

Failing to maintain spark plugs properly can lead to several annoying issues: rough idling, engine hesitation, poor acceleration and reduced fuel economy being the most common. In severe cases, worn spark plugs might even cause engine warning lights to come on. Spotting these symptoms early means you can get your spark plugs replaced before bigger problems occur.

Along with spark plug replacement, it's a good idea to regularly check ignition coils and the spark plug wiring on your Commodore. This keeps the entire ignition system firing as it should, supporting better engine performance and reliability. Good ignition also helps the car meet emissions standards and maintains smooth driving characteristics that Holden owners expect.

In short, spark plugs on the 2017 Holden Commodore are an essential, if often overlooked, part of the car's petrol engine system. They provide the spark that brings your engine to life and keeps it running efficiently. Replacing them at recommended intervals, using the right parts, and keeping the ignition system in good shape will help maintain performance, fuel economy and avoid unnecessary trips to the mechanic.

For those enjoying a 2017 Holden Commodore, treating the spark plugs like a basic yet crucial maintenance item can make a noticeable difference in how the car drives. Plus, staying on top of this small component can extend the overall life of the engine, making sure your Commodore remains a trusted car for many kilometres to come.
