Parts for your 2022 Mitsubishi Eclipse cross-Spark plugs

2022 Mitsubishi Eclipse Cross spark plugs

Yes, spark plugs are absolutely relevant to the 2022 Mitsubishi Eclipse Cross. Mitsubishi Motors service literature for the GK/GL-series Eclipse Cross (including the 1.5‑litre MIVEC turbo petrol and the Eclipse Cross Plug‑in Hybrid’s 2.4‑litre Atkinson‑cycle petrol), the 2022 owner’s handbook maintenance schedule, and NGK/DENSO fitment catalogues all specify iridium spark plugs for these models. With no diesel option for 2022 in AU/NZ, the Eclipse Cross lineup uses petrol engines that rely on spark plugs for ignition.

In day‑to‑day terms, the spark plugs fire a precise, high‑voltage spark that ignites the air‑fuel mix in each cylinder. That’s what gives the Eclipse Cross its smooth idle, crisp throttle response and decent fuel economy. On the turbo 1.5T, the plugs work in hotter, higher‑pressure conditions, so correct heat range and healthy coils are especially important. On the PHEV, the engine doesn’t run all the time, but when it does kick in, reliable spark is key to seamless hybrid operation.

As part of servicing, spark plugs are a small part that makes a big difference. Mitsubishi specifies long‑life iridium plugs, in typical use these often run 90,000–120,000 kilometres before replacement, but always follow the exact interval in the owner’s handbook for the specific engine and driving conditions. Short urban trips, frequent cold starts, dusty environments and sustained towing or high‑load driving can bring that interval forward.

• Use OEM‑grade iridium plugs matched to the engine specification, avoid mixing heat ranges.
• Replace all plugs as a set and inspect coil boots for cracking or carbon tracking, renew boots if needed.
• Iridium plugs are pre‑gapped—don’t force the ground strap, if the gap is out, replace the plug.
• Work on a cool engine, blow debris from plug wells, and torque to spec from the service manual. Don’t use anti‑seize unless the plug manufacturer says so.

If the Eclipse Cross starts a bit rough, idles lumpy, uses more fuel than usual, hesitates under load, or flashes the check‑engine light with misfire codes, the plugs (or coils) could be due. For PHEV owners, note that time‑based replacement can still apply even if kilometres are low, because age and heat cycles affect plugs and boots.

Done right, fresh plugs help the 2022 Eclipse Cross start cleanly on chilly mornings, pull strongly onto the motorway and keep emissions in check—under the bonnet reliability you can feel from the driver’s seat.

How often should the 2022 Eclipse Cross spark plugs be replaced?

Most 2022 models use long‑life iridium plugs that typically go 90,000–120,000 kilometres in normal Aussie and Kiwi driving. Severe service—lots of short trips, dust, towing or high heat—can shorten that. Always follow the interval in the owner’s handbook for the exact engine and conditions. PHEV owners should also observe time‑based replacement even if kilometres are low.

What type of spark plug does the 2022 Eclipse Cross use?

Iridium‑tipped plugs to Mitsubishi’s spec are called for on both the 1.5‑litre turbo petrol and the PHEV’s 2.4‑litre petrol. OEM‑equivalent plugs from major brands (as listed in NGK and DENSO application guides) are fine—just match the engine code and heat range.

What are the signs the spark plugs need attention?

Hard starting, rough idle, sluggish acceleration, higher fuel use, or a check‑engine light—often with misfire codes—are common signs. If any of these pop up, a quick inspection of plugs and coil boots under the bonnet is a smart first step.
