Ignition Leads on the 2017 Subaru Outback: What You Need to Know

When it comes to the ignition system in a 2017 Subaru Outback, it's important to understand whether ignition leads play a role or not. The truth is, the 2017 Subaru Outback does not use traditional ignition leads. Instead, it features a more modern ignition system that relies on coil-on-plug ignition technology.

Ignition leads, also known as spark plug wires, have been a common part of petrol engine ignition systems for many decades. Their job is to carry the high voltage current from the ignition coil to the spark plugs. However, cars like the 2017 Subaru Outback have moved beyond this setup by using individual ignition coils mounted directly on top of each spark plug. This design eliminates the need for ignition leads entirely.

So why did Subaru choose to ditch the ignition leads? There are a few solid reasons. Coil-on-plug systems provide a more efficient and reliable spark delivery. Without ignition leads, there's less chance of current loss or interference, which can happen due to wear and tear of ignition wires over time. This leads to improved engine performance, better fuel efficiency, and reduced emissions. Plus, coil-on-plug systems require less maintenance overall, which is a bonus for Outback owners looking for hassle-free motoring.

Since the 2017 Subaru Outback does not have ignition leads, traditional maintenance or replacement of these parts is not necessary. Instead, owners should focus on the ignition coils and spark plugs themselves as part of regular servicing. The ignition coils need to be checked for signs of damage or failure, which might include engine misfires, rough idling, or difficulty starting. Spark plugs should be inspected and replaced as per Subaru's recommended service intervals to ensure consistent performance and fuel economy.

For those familiar with older vehicles that had ignition leads, it might be helpful to think of the coil-on-plug setup as a more streamlined, low-maintenance upgrade. There are no wires to degrade or fall off, no concerns about cracking insulation or carbon tracking that can cause misfires. It's simply a cleaner, more reliable electrical connection from the ignition coil to each spark plug.

If an owner experiences ignition issues with a 2017 Subaru Outback, the service focus should be on testing the ignition coils, spark plugs, and associated connections. Diagnostics can quickly pinpoint if a coil is faulty or if plugs have reached their life span. Replacement of these components is straightforward and usually requires minimal labour compared to older ignition lead systems.

In general, the absence of ignition leads on the 2017 Subaru Outback means fewer parts to worry about and a reduced risk of ignition-related faults caused by the degradation of high-voltage wires. This modernisation reflects the continuous improvements in automotive technology, designed to give drivers better reliability and peace of mind.

In summary, ignition leads are not relevant or used on the 2017 Subaru Outback due to the coil-on-plug ignition system. This system provides a more efficient, reliable, and low-maintenance solution for spark delivery directly from the coils to the spark plugs. For owners, the key components to keep an eye on are the ignition coils and spark plugs. Keeping these in good condition will ensure the Outback runs smoothly without the worry of old-style ignition lead problems.
