Ignition Coils and Their Role in the 2018 Subaru Exiga

The 2018 Subaru Exiga is a versatile and reliable vehicle built with a robust engine management system that incorporates ignition coils as a crucial component. Ignition coils are very much relevant and fitted in the 2018 Subaru Exiga, playing a key role in the vehicle's ignition system. They are responsible for converting the low voltage from the battery into the high voltage needed to create a spark at the spark plugs, igniting the air-fuel mixture in the engine's combustion chambers.

In a petrol-powered vehicle like the Subaru Exiga, ignition coils are indispensable. Without them, the engine simply will not start or run efficiently. The 2018 model uses electronic ignition coils, often referred to as coil-on-plug units. This setup places one coil directly on top of each spark plug, improving ignition reliability and efficiency compared to older distributor-based systems.

Understanding the purpose of ignition coils helps when it comes to servicing and maintenance. The ignition coil takes 12 volts from the battery and steps it up to around 20,000 volts or more. This high voltage is necessary to create a strong spark that jumps the gap in the spark plug, igniting the fuel-air mixture inside each cylinder. Efficient ignition coils ensure that the engine runs smoothly, produces optimal power, reduces emissions, and fosters better fuel economy.

When ignition coils start to fail, symptoms like rough idling, misfires, reduced fuel efficiency, and difficulty starting the engine can appear. Over time, ignition coils are subjected to heat, vibration, and electrical wear. This makes them one of those parts to keep an eye on during your Subaru Exiga's regular servicing.

Given their vital role, ignition coil replacement or maintenance should be included as part of the routine care of the 2018 Subaru Exiga. When replacing ignition coils, it is highly recommended to use genuine or OEM parts to maintain reliability and performance. Aftermarket coils can be cheaper but might not meet the same quality standards, potentially leading to further engine troubles down the track.

Here are some practical tips for ignition coil care and maintenance on your 2018 Subaru Exiga:

  • Keep an eye on your check engine light. Modern Subaru models including the Exiga will trigger the engine management system to alert you if there's a misfire or ignition coil fault.
  • Whenever doing spark plug replacement, it's a smart idea to inspect the coils. Any signs of cracks, carbon tracking, or corrosion on the coil boots should prompt replacement.
  • If you experience engine hesitation or rough running, have the ignition coils tested by a professional. Diagnostic tools can quickly pinpoint coil failure.
  • Resist the temptation to ignore coil failure symptoms since prolonged misfires can damage your catalytic converter and other engine components in the Subaru.
  • Follow the vehicle's service schedule recommended by Subaru, as coils typically last many tens of thousands of kilometres but will eventually wear out.

Ignition coils are also designed to work in harmony with the vehicle's engine control unit (ECU), adjusting spark timing to match varying driving conditions and load. This makes the coils not just a static electrical part but a component integrated into the vehicle's sophisticated engine management system.

For Subaru Exiga owners in Australia, harsh weather conditions and the dusty environment can accelerate wear on ignition components, so regular checks are worthwhile. Regular servicing at an authorised workshop familiar with Subarus will ensure that ignition coils and the wider ignition system get the attention they deserve, helping to protect both performance and fuel economy.

Overall, the ignition coils fitted on the 2018 Subaru Exiga are essential for the engine to operate correctly. Keeping these coils in tip-top shape ensures that your car starts easily, runs smoothly, and performs efficiently. Ignition coil maintenance is a small but important part of your car's overall health and longevity, and careful attention can save money and hassle down the track.
