Parts for your 2022 Subaru Xv-Ignition coils

2022 Subaru XV ignition coils — what they do and when to replace

Yes, the 2022 Subaru XV uses ignition coils. This is confirmed by Subaru’s Factory Service Manual (STIS) for the FB-series petrol engines fitted to the XV (including the e-BOXER hybrid), which specifies a coil-on-plug system, and by Subaru’s official parts catalogues for MY22 XV/GT series that list individual ignition coil units for each cylinder.

On the XV, each cylinder gets its own coil-on-plug module. Those coils take the 12-volt supply and step it up to the high voltage needed to jump the spark plug gap, precisely timed by the ECU. Whether it’s the 2.0-litre FB20 or the hybrid variant, the boxer engine relies on these coils for clean starts, smooth idle and strong pull across the rev range.

Ignition coils aren’t a scheduled replacement item in normal conditions, but they should be inspected during routine services. Technicians will look for cracking, heat discolouration, oil in the plug tubes from rocker cover leaks, or corrosion at the terminals. If the XV throws a misfire code (P0300–P0304) or an ignition circuit fault (P0351–P0354), a coil is high on the suspect list. Classic symptoms include rough idle, hesitation, poor fuel economy and a flashing check engine light under load.

Good workshop practice with the 2022 XV is simple: keep moisture out of the plug wells, use a dab of dielectric grease on the boots, and replace spark plugs at the interval in Subaru’s service schedule (often around 100,000 kilometres for iridium). Always torque new plugs to the specification in the Subaru manual and seat coils squarely to avoid arcing. If one coil fails at high mileage, many owners choose to replace the full set to restore consistency, though a single replacement is fine if the rest test OK.

When it’s time to swap a coil, go for genuine Subaru or a high-quality equivalent that meets OE specs. Disconnect the battery, handle the connectors gently under the bonnet, and clear any stored codes after repair. A healthy battery and clean grounds also help coil life by preventing voltage spikes. Look after the ignition system and the XV’s smooth, fuss-free character stays right where it should be.

• Watch for misfire codes and rough running, especially under load.
• Inspect coils and plug tubes during major services.
• Replace plugs on schedule, fit coils carefully and to spec.

Popular questions about 2022 Subaru XV ignition coils

Does the 2022 Subaru XV have individual ignition coils?

It does. The XV’s FB-series boxer uses a coil-on-plug layout with one coil per cylinder, as detailed in Subaru’s Factory Service Manual and parts listings for MY22. There are no traditional plug leads.

How long do the coils typically last on a 2022 XV?

Many last well past 100,000 kilometres. They’re not a routine replacement item, but age, heat, oil contamination in plug tubes or low battery voltage can shorten life. Replace only when testing or fault codes point to a coil issue.

What are the signs of a failing ignition coil, and is it safe to drive?

Rough idle, hesitation, poor economy, and a check engine light (often with P03xx codes) are common. Driving with a misfire can damage the catalytic converter, so it’s best to have it checked and fixed promptly.
