Ignition Coils on the 2008 Subaru Exiga: What They Do and How to Keep Them in Top Shape

The 2008 Subaru Exiga, a versatile and family-friendly vehicle, does indeed use ignition coils as part of its ignition system. Ignition coils play a crucial role in ensuring the engine runs smoothly by transforming the battery's low voltage into the high voltage needed to ignite the air-fuel mixture inside the engine cylinders. Without ignition coils, the engine simply wouldn't fire up or operate efficiently.

So, what exactly are ignition coils and how do they work in the 2008 Subaru Exiga? Ignition coils are essentially small transformers. In cars like the Exiga that feature a modern coil-on-plug ignition system, each cylinder typically has its own ignition coil mounted directly on top of the spark plug. This design eliminates the need for older-style distributor systems or spark plug wires, ensuring a more reliable spark and better engine performance overall.

The basic function of ignition coils is to take the 12-volt power supplied by the car's battery and jump it up to thousands of volts. This high voltage is necessary to create a spark that can ignite the fuel-air mixture in the combustion chamber. Without this high-voltage spark, the engine wouldn't start or run properly.

In the 2008 Subaru Exiga, ignition coils are an integral part of the Sequential Multi-Point Fuel Injection system and engine management. The vehicle's Engine Control Unit (ECU) precisely controls the timing and firing of each coil to optimise performance, fuel economy, and emissions. This means the coils have to work efficiently and reliably, making their maintenance important to the overall health of the vehicle.

When it comes to maintaining ignition coils on the 2008 Subaru Exiga, regular servicing and inspections are advisable. Although ignition coils don't have a fixed replacement interval like some parts, keeping an eye on their condition can prevent unexpected engine misfires or rough running. Some common symptoms of failing ignition coils include:

• Engine misfires or hesitation during acceleration
• Rough or unstable idling
• Poor fuel economy
• Difficulty starting the engine
• Illuminated check engine light

If any of these symptoms show up, it's a good idea to have the ignition coils checked during servicing. Mechanics generally use diagnostic tools to detect misfires or coil failures by reading fault codes stored in the car's ECU. Physically, ignition coils can sometimes be inspected for signs of damage such as cracks in the casing or corrosion on electrical connectors.

Replacing ignition coils on the 2008 Subaru Exiga is often a straightforward process because the coils are mounted directly onto the spark plugs. When replacing the coils, it's usually recommended to replace the spark plugs as well. This is because coil failure sometimes happens due to increased resistance caused by worn spark plugs, and installing new plugs can help prevent premature coil failure.

Regular maintenance tips for ignition coils include:

• Checking ignition coils and spark plugs for wear every 60,000 to 100,000 kilometres depending on driving conditions and manufacturer guidelines
• Ensuring connectors and wiring harnesses are clean and free from corrosion
• Replacing coils in pairs or sets if one coil shows failure to maintain balanced engine performance
• Using genuine or high-quality replacement parts to avoid compatibility problems and ensure long life

Many Subaru owners report that well-maintained ignition coils can easily last beyond 100,000 kilometres, but keeping an eye on the coil and spark plug condition during regular servicing is key. Ignition coil failure not only affects drivability but can also lead to increased emissions and potential damage to other engine components if ignored.

In everyday driving around Australia, from urban commuting to highway cruising, the ignition coils must deliver consistent performance regardless of weather or road conditions. Thanks to Subaru's durable parts and well-engineered ignition system, the 2008 Exiga is built to handle these demands. Still, treating ignition coil maintenance as a routine part of servicing is the best way to keep this multi-purpose vehicle running happily over the long haul.

So if you're keeping your 2008 Subaru Exiga in tip-top condition, don't forget about the humble ignition coils. They might be small and often go unnoticed but they are vital for that smooth start every time you hit the key and drive off. Are the coils checked regularly as part of your servicing? It's definitely worth asking your mechanic to take a quick look - and replace those coils if there's any sign of trouble.
