Parts for your 2023 Mitsubishi Eclipse cross-Air filter

2023 Mitsubishi Eclipse Cross air filter — what it does and when to change it

Yes, the 2023 Mitsubishi Eclipse Cross uses an engine air filter (air cleaner element). Mitsubishi’s 2023 Eclipse Cross Owner’s Manual and the Australia/New Zealand Service and Warranty Booklet list the engine air cleaner as a routine maintenance item, to be inspected at each scheduled service and replaced at mileage/age intervals depending on conditions.

The air filter’s whole job is to feed the 1.5L turbo petrol (and the 2.4L petrol in the PHEV) clean air while keeping out dust, sand and road grime. That protects the turbo and intake tract, helps the mass airflow and boost control sensors read accurately, and keeps the fuel–air mix spot on. A healthy filter means smoother drivability, better fuel economy and lower emissions. Let it clog and you’ll notice lazier acceleration, a bit more thirst, and potentially more intake noise.

Servicing-wise, Mitsubishi schedules the Eclipse Cross for regular checks at 12 months/15,000 km. The engine air filter is typically inspected at each visit and replaced around 30,000–60,000 km, sooner if you’re doing dusty rural or unsealed-road driving. Those intervals are consistent with Mitsubishi’s published guidance for AU/NZ, your tech will adjust based on what they see under the bonnet.

• When it’s time: sluggish performance, increased fuel use, or a visibly dark, dirty pleat pack are giveaways.
• Dusty conditions: if you’re touring gravel or outback roads, ask for an inspection every 10,000–15,000 km.
• PHEV owners: there’s still a conventional engine air filter, plus a separate cabin (pollen) filter. Different parts, different jobs.

1. DIY check: with the engine off, pop the airbox clips, lift the lid and inspect the element against light. Pale tan is fine, sooty/blocked needs replacing.
2. Cleaning: don’t blast paper filters with compressed air (it can tear fibres). If it’s borderline, a gentle tap to drop loose dust is okay, but replacement is the go if it looks loaded.
3. Refit: seat the gasket evenly and secure the airbox so unfiltered air can’t bypass the seal.

Using a quality filter that meets OEM spec is smart—genuine or reputable aftermarket are both fine. Keep it on the service sheet and the Eclipse Cross will breathe easy.

Popular questions

How often should the 2023 Eclipse Cross engine air filter be replaced?
For Australia and New Zealand, it’s inspected at every 15,000 km/12‑month service and commonly replaced around 30,000–60,000 km. If you regularly drive in dusty areas, plan on shorter intervals and more frequent checks.

Does the Eclipse Cross PHEV use the same air filter as the petrol model?
It also uses an engine air filter, but the part number can differ between engines. The PHEV additionally has a cabin microfilter for the HVAC system—separate from the engine air filter.

What are the signs the air filter needs attention?
Poor acceleration, higher fuel use, a darker/sooty filter element, or unusual intake noise. If you see any of these, ask your technician to inspect or replace the filter at your next service.
