Parts for your 2022 Honda Civic-Spark plugs

2022 Honda Civic spark plugs: what they do and when to replace them

Yes, the 2022 Honda Civic uses spark plugs. Both the 1.5‑litre turbo and 2.0‑litre petrol engines are spark‑ignition designs that rely on iridium spark plugs for combustion. This is backed by Honda’s Owner’s Manual and Maintenance Minder system (sub‑code 4 calls for spark plug replacement), as well as major plug catalogues from NGK and Denso that list specific iridium plugs for the 2022 Civic. Fully electric vehicles and diesels don’t use spark plugs, but the 2022 Civic isn’t one of those.

Spark plugs are the small but critical components that ignite the air‑fuel mix inside the cylinders. In the 2022 Civic, fine‑wire iridium plugs deliver a strong, stable spark, helping cold starts, smooth idle, fuel economy and punchy throttle response. They also resist wear better than old‑school copper plugs, which is why service intervals are longer.

For servicing in Australia and New Zealand, owners should follow the car’s Maintenance Minder. Expect spark plug replacement roughly between 100,000 and 160,000 kilometres, depending on engine and driving conditions. Short trips, dusty roads, frequent idling or regular towing can bring that forward. If the Minder flags sub‑code 4, it’s time.

• Watch for signs of tired plugs: rough idle, misfire under load, sluggish acceleration, poorer fuel use, or a check‑engine light.
• Use plugs that meet Honda’s specification (iridium, correct heat range and reach). Mixing types can cause misfires or engine damage.
• Plugs are typically pre‑gapped, don’t force the gap on iridium fine‑wire tips. Confirm the spec on the under‑bonnet label or in the manual.
• Avoid anti‑seize on modern, nickel‑plated threads (as advised by NGK/Denso), it can alter torque. Fit to the workshop torque spec and work on a cool engine.

Good workshops will replace all plugs as a set, inspect ignition coils and boots for tracking, and check for oil in the plug tubes (a rocker cover seal issue). DIY owners with the right tools can manage the job, but it’s easy to over‑tighten or crack an insulator. If in doubt, leave it to a trusted technician.

Staying on top of spark plugs keeps the Civic running sweet, helps with emissions, and can save money at the bowser. Simple part, big impact.

Do all 2022 Honda Civics, including hybrids, use spark plugs?

Yes. All 2022 Civic petrol variants, including hybrid versions where available, use spark plugs to ignite the air‑fuel mixture. Only full EVs and diesels don’t use them. Honda service information and major plug catalogues confirm fitment.

How often should the spark plugs be replaced on a 2022 Civic in Australia/NZ?

Typically between 100,000 and 160,000 kilometres, or when the Maintenance Minder shows sub‑code 4. Heavy city use, dusty conditions or lots of short trips can shorten the interval, so always follow the Minder and the owner’s manual.

Can owners regap or reuse the original plugs?

Iridium plugs are designed with a fine centre electrode and are usually pre‑gapped. Don’t force the gap or file the tip. Reuse isn’t recommended once they’re worn or fouled—fit the correct iridium replacements and torque them properly.
