Parts for your 2012 Subaru Exiga-Ignition coils

Ignition Coils for the 2012 Subaru Exiga: What You Need to Know

The 2012 Subaru Exiga is a versatile and spacious vehicle, popular for families and those wanting a reliable multi-purpose ride. When it comes to how this vehicle starts and runs, one crucial component that often gets overlooked is the ignition coil. The good news for Exiga owners is that ignition coils are indeed a part of the vehicle's ignition system, playing an essential role in ensuring the engine fires up smoothly and runs efficiently.

Ignition coils are responsible for converting the low voltage from the car's 12-volt battery into the much higher voltage needed to create a spark at the spark plugs. This spark is what ignites the air-fuel mixture in the engine's cylinders, ultimately powering the vehicle. Without a properly functioning ignition coil, the engine wouldn't start or would run poorly, leading to misfires, rough running, and reduced fuel efficiency.

In the case of the 2012 Subaru Exiga, ignition coils are indeed fitted and integral to the vehicle's operation. The car uses a coil-on-plug system where each cylinder has its own ignition coil mounted directly above the spark plug. This setup improves reliability and ignition performance by eliminating the traditional spark plug wires, which can degrade over time.

Because ignition coils are critical to engine performance, partly maintaining or replacing them during regular servicing is a good idea. Here's what to keep in mind if you're looking after the ignition coils on a 2012 Subaru Exiga.

• Signs of Faulty Ignition Coils: Drivers might notice engine misfires, rough idling, stalling, or even a drop in fuel economy. Often, the check engine light will come on with trouble codes related to ignition coil failure. These symptoms indicate it's time to have the ignition coils inspected and possibly replaced.
• Routine Inspection: When servicing your Exiga, mechanics typically check the ignition coils for any signs of damage or wear. Cracks, corrosion, or burnt areas on the coil housing may signal a coil nearing failure.
• Replacement Intervals: While ignition coils do not have a fixed replacement interval like oil or filters, they generally last between 100,000 to 150,000 kilometres. However, this can vary depending on driving conditions and maintenance history.
• Maintenance Tips: Keeping the ignition system healthy involves more than just the coils themselves. Regularly replacing spark plugs and ensuring good battery health complements coil longevity. If one coil is faulty, it is often recommended to replace all of them at once to maintain balanced engine timing and performance.

When it comes time to replace ignition coils on your Subaru Exiga, make sure to use quality, compatible parts designed for your specific engine model. Subaru's boxer engine layouts often require coils that can handle their unique design, so sourcing ignition coils from reliable suppliers or genuine Subaru parts stores is always the safest bet.

The installation process is relatively straightforward but does require some mechanical know-how. Technicians will disconnect the battery, remove engine covers to access the coils mounted on the cylinder head, and carefully unplug the electrical connectors before swapping old coils for new ones. It's important to handle ignition coils carefully, as they are sensitive to damage from impacts or dirt.

Overall, the ignition coil is a small but mighty component ensuring your 2012 Subaru Exiga starts reliably and runs smoothly. While it might not be the flashiest part under the bonnet, its role in powering the engine cannot be overstated. Keeping ignition coils in top shape through regular checks and timely replacements can save headaches and keep your Exiga cruising comfortably for years to come.

For Aussie Exiga owners, staying on top of ignition coil health means fewer surprises on those long highway trips or weekend adventures. Next time the service interval rolls around or you notice signs of engine hiccups, don't overlook the ignition coils - they just might be the key to better driving performance and reliability.
