Spark Plugs on the 2017 Subaru XV: What You Need to Know

The 2017 Subaru XV, also known as the Crosstrek in some markets, is a popular compact SUV that uses a petrol-powered internal combustion engine. When it comes to the question of whether spark plugs are relevant or used on this vehicle, the answer is clear: yes, spark plugs are absolutely a crucial component of the 2017 Subaru XV's engine system.

Spark plugs play an essential role in petrol engines, and since the 2017 Subaru XV is equipped with a petrol engine - specifically, Subaru's well-known Horizontally Opposed (Boxer) engine - it certainly relies on spark plugs to keep the engine running smoothly.

Now, some might wonder if newer vehicles might skip spark plugs for other technologies, such as diesel engines or electric powertrains. Diesel engines do not use spark plugs, instead, they use compression ignition. However, the 2017 Subaru XV does not have a diesel or fully electric variant that would avoid spark plugs entirely. So, if you own or service a 2017 Subaru XV, spark plugs are part of your maintenance routine.

So what exactly do spark plugs do? Well, a spark plug's job is to ignite the air-fuel mixture inside the engine's cylinders at the right time, creating the controlled explosion that powers the engine. Without spark plugs, the petrol engine simply won't run because there's no spark to ignite the fuel. In the Boxer engine of the XV, every cylinder has a spark plug, usually one per cylinder, optimised for efficient combustion.

Because spark plugs are small but vital, understanding their maintenance is important to keep your 2017 Subaru XV running well. Here's a bit more info on what owners should know about spark plug care and replacement:

• Purpose of Spark Plugs: They initiate combustion by producing a high voltage spark in the combustion chamber, setting off the fuel-air mix and driving the piston down, which then powers your car.
• Types Used in the 2017 Subaru XV: Subaru typically fits iridium-tipped spark plugs in the Boxer engines for this model and year. These offer better longevity and performance than older copper plugs.
• Recommended Replacement Interval: Subaru generally suggests replacing spark plugs every 60,000 to 100,000 kilometres depending on the specific engine variant and driving conditions. But it's a good idea to check the owner's manual or chat to a Subaru service centre for the exact interval.
• Signs That Spark Plugs Need Attention: If the engine is misfiring, idling roughly, or showing reduced fuel efficiency, it could be worn spark plugs causing the problem. Strange noises like engine knocking may also hint at plug issues.

When it's time to service those spark plugs, here's what is usually involved:

1. Accessing the Spark Plugs: Due to the Boxer engine's design, the plugs are positioned horizontally and may require removing the engine cover or air intake parts for easy access.
2. Inspection: Mechanics will check the spark plugs for wear, deposits, and electrode erosion. These factors affect how well the plugs spark, so worn plugs should be swapped for new ones.
3. Replacement: Using the correct specified electric gap and torque settings is important to avoid damage. Subaru spark plugs come pre-gapped for the XV, but a quick check is always recommended to ensure optimum performance.
4. Extra Tips: It's wise to change spark plugs as a set to maintain uniform performance across all cylinders.

Routine spark plug maintenance is affordable and can make a big difference to the XV's fuel economy, smoothness, and overall engine health. Neglecting spark plug replacement can lead to rough starts, poor acceleration, and increased emissions, which Aussie drivers won't appreciate with rising fuel costs and emissions regulations.

For those keen on DIY, changing spark plugs on the 2017 Subaru XV isn't too tricky if you have the right tools like a spark plug socket, ratchet, and gap gauge. However, if you're unsure, it's worth getting a qualified mechanic to handle it because improper installation might lead to engine damage or misfiring issues.

Ultimately, spark plugs are small but mighty components that deserve a bit of attention in every Subaru XV's servicing schedule. Whether it's a trip to the suburb or an outback adventure, well-maintained spark plugs will help ensure your 2017 Subaru XV stays reliable and efficient mile after mile.
