2017 Subaru Exiga Air Filter: Purpose and Maintenance Tips

The 2017 Subaru Exiga definitely comes equipped with an air filter as a key part of its engine system. Like most modern vehicles, the air filter plays a crucial role in ensuring the engine runs smoothly and efficiently. It is not one of those optional extras, it is essential for the health and performance of the car's engine.

So what's the purpose of the air filter in the 2017 Subaru Exiga? Simply put, the air filter cleans the air before it enters the engine. The engine relies on a precise mix of air and fuel to ignite and power the vehicle. Outside air contains dust, dirt, pollen, and other contaminants - all of which can cause damage if they get inside the engine. The air filter acts like a barrier, trapping these particles and preventing them from entering the combustion chamber.

By keeping the air clean, the air filter helps maintain engine efficiency and prolongs the life of vital components like the cylinders, pistons, and spark plugs. A clean air filter ensures optimal air flow, which is important for fuel combustion, engine power, and fuel economy. When the filter is clogged, airflow is restricted, which can lead to reduced performance, lower fuel efficiency, and increased emissions.

Replacing or maintaining the air filter on a 2017 Subaru Exiga is a smart part of any regular servicing routine. Subaru recommends checking the air filter every 12,000 to 15,000 kilometres or at least once a year, whichever comes first. However, this interval can vary depending on driving conditions. For example, if the car is often driven on dusty roads or in urban environments with heavy pollution, the air filter may need to be replaced more frequently.

Keeping up with air filter maintenance can be pretty straightforward. Most air filters on the Exiga are easily accessible under the bonnet. A quick visual check can give a good idea of its condition. If the filter looks dark, clogged or dirty, it's definitely time for a replacement. Many Subaru owners also prefer to have their air filter checked by a professional during regular service appointments to ensure it's performing as it should.

Replacing the air filter is generally a quick and affordable task. Genuine Subaru air filters are designed to fit the Exiga perfectly, ensuring that the filtration system works correctly. While there are aftermarket options available, sticking with a manufacturer-approved air filter is usually recommended for the best balance of filtration efficiency and engine protection.

One thing to remember is that a poorly maintained air filter can lead to other issues beyond just engine performance. A dirty or blocked filter can cause the engine to run rich, meaning more fuel than necessary is burnt. This can result in fouled spark plugs, increased emissions, and, over time, potential damage to the catalytic converter. Plus, it can make the car feel sluggish, with less power when accelerating.

It's also worth noting that the Subaru Exiga uses a traditional paper air filter element rather than an oiled or reusable filter. These paper filters are disposed of and replaced rather than cleaned and reused. Attempting to clean a paper air filter with compressed air or water is not advised as it can damage the filter material and reduce its effectiveness.

For those who enjoy DIY car maintenance, changing the air filter on the 2017 Subaru Exiga is a manageable job with basic tools. The air filter housing is typically held together with clips or screws, and there are numerous online guides and videos showing the process step-by-step. However, if there is any doubt, taking the car to a Subaru dealership or a reputable service centre is a good idea to ensure the job is done right.

In the end, the air filter is a small but mighty component of the 2017 Subaru Exiga. It doesn't get as much attention as tyres or brakes, but its role in protecting the engine and keeping the car running smoothly is vital. Regularly checking and replacing the air filter is a simple and cost-effective way to maintain the vehicle's performance, improve fuel efficiency, and avoid costly repairs down the track.
