Parts for your 2016 Subaru Exiga-Ignition leads

2016 Subaru Exiga ignition leads — are they a thing?

Short answer: no. The 2016 Subaru Exiga (sold in this era as the Exiga Crossover 7 in Japan) doesn’t use traditional ignition leads. Instead, it runs a modern coil-on-plug (COP) ignition system, where an individual ignition coil sits directly on top of each spark plug. That means there are no long high-tension leads to route or replace.

This setup is standard on the FB25 2.5-litre engine used in the 2016 Exiga Crossover 7, and even earlier turbo EJ variants in the Exiga line used individual coil packs rather than conventional leads. The design improves spark energy, reduces electrical losses, cuts radio interference, and helps emissions and fuel economy. It also simplifies diagnostics, as faults are isolated per cylinder.

What does that mean for servicing? There’s no “ignition-leads” service on this vehicle. Instead, technicians should focus on:

• Replacing spark plugs at the recommended interval (typically around 100,000 km for iridium plugs, or as per the owner’s schedule for local conditions).
• Inspecting the coil boots and seals for heat hardening, cracking, or oil contamination from rocker cover gaskets.
• Checking coil electrical connectors for corrosion or loose pins if there’s a misfire code.

If someone’s trying to sell a set of ignition leads for a 2016 Exiga, they won’t fit because the engine simply doesn’t use them. Any misfire or rough running is more likely to be a worn plug, a failing individual coil, intake/PCV issues, or fuel/air problems rather than a “bad lead.”

Technical sources supporting this: Subaru service manuals for the Exiga Crossover 7 (FB25) list “Ignition Coil” per cylinder and do not list high-tension leads, Subaru Japan Electronic Parts Catalogue shows coil assemblies and spark plugs but no plug cords for 2015–2018 Exiga Crossover 7, Subaru’s model literature for the Exiga Crossover 7 confirms the FB25 engine, which is a coil-on-plug design. These documents collectively establish that ignition leads aren’t fitted to the 2016 Exiga.

Popular questions

Does a 2016 Subaru Exiga have ignition leads?
No. It uses a coil-on-plug ignition system, so there are individual coils on each spark plug and no traditional high-tension leads.

What should be serviced instead of ignition leads on a 2016 Exiga?
Replace spark plugs at the specified interval and inspect coil boots, coil operation, and connectors. Address any oil leaks that could contaminate the coil boots.

Can aftermarket ignition leads improve performance on a 2016 Exiga?
They can’t be fitted because the engine doesn’t use them. If chasing performance or smoother running, focus on quality iridium plugs, healthy coils, clean intake components, and up-to-date software and maintenance.
