Parts for your 2022 Toyota C-hr-Spark plugs

2022 Toyota C‑HR Spark Plugs

Yes, spark plugs are fitted to the 2022 Toyota C‑HR. Technical sources that confirm this include the Toyota C‑HR Owner’s Manual (AU/NZ, 2022 model year), Toyota’s factory Repair Manual and Electronic Parts Catalogue, and major ignition parts catalogues from Denso and NGK. Both the 1.2‑litre turbo-petrol and the 1.8‑litre hybrid (which still has a petrol Atkinson‑cycle engine) are spark‑ignition engines specified with long‑life iridium spark plugs.

On a 2022 C‑HR, the spark plugs are there to ignite the air‑fuel mixture in each cylinder at precisely the right moment. That crisp, consistent spark keeps starts quick, idle smooth, fuel use in check, and emissions under control. Toyota equips the C‑HR with iridium fine‑tip plugs because they run cleaner and last far longer than older copper designs, which suits modern coil‑on‑plug ignition systems and tight service schedules.

For servicing in Australia and New Zealand, the spark plugs are generally a long‑interval item. Expect replacement around 120,000 kilometres or 6 years for most schedules. Some hybrid schedules may extend further, but the owner’s logbook is the final word. Even between changes, it’s smart for a technician to inspect the plugs during major services—checking electrode wear, colour (rich/lean clues), and signs of oil or coolant contamination that might hint at other issues.

If replacement is due, use quality iridium plugs that match the exact Toyota spec (heat range, reach, thread, terminal style). Plugs normally come pre‑gapped and shouldn’t be re‑gapped aggressively. A torque wrench should be used to the factory spec in the Toyota Repair Manual
