Parts for your 2020 Mitsubishi Outlander-Cabin filter

2020 Mitsubishi Outlander cabin filter — fitment, purpose and servicing advice

Yes — the 2020 Mitsubishi Outlander is built with a cabin air filter. This is confirmed by multiple technical sources: the Mitsubishi Motors Outlander Owner’s Manual (Air conditioner filter section), the factory Service Manual (HVAC/Heater & Air Conditioning group, which details a behind‑glovebox filter service procedure), the Mitsubishi ASA parts catalogue listing an “Air Conditioner Filter” for ZJ/ZK/ZL Outlander models, and AU/NZ aftermarket application guides (for example, Ryco’s listing for Outlander ZJ–ZL showing a direct-fit cabin filter). With that squared away, here’s what that filter does and how it should be looked after during servicing.

In a 2020 Outlander, the cabin filter cleans incoming air before it reaches the vents. It helps trap dust, pollen, road grime, soot and fine particles from bushfire smoke, and can reduce odours and fumes if a carbon-impregnated type is used. Keeping the filter fresh protects the blower motor, keeps the evaporator cleaner (reducing musty smells and mould risk), and preserves good airflow so the demister and A/C don’t feel weak.

For AU and NZ conditions, it’s smart to have it inspected at each service (about every 10,000–15,000 kilometres or 12 months), and replaced roughly every 15,000–30,000 kilometres or 1–2 years depending on where it’s driven. City commuting, unsealed roads, frequent pollen seasons, or smoke exposure all justify earlier replacement. Many owners step up to an activated carbon or anti-microbial element for better odour and fume control.

The filter sits behind the glovebox. The glovebox typically drops down by releasing the side stops, the filter tray then slides out, letting the old element be swapped. It’s a quick, tool-light job, but the airflow arrow must face the correct direction. A genuine Mitsubishi element (commonly 7803A006 or superseded number) or a quality aftermarket equivalent (e.g., Ryco RCA164P) will fit, choosing reputable media avoids shedding fibres and poor sealing.

• Signs it’s due: reduced airflow even with the fan high, persistent window fogging, musty odours shortly after start-up, or a visibly grey/brown, debris-laden element.
• Service tips: check for leaves and debris in the plenum, keep the evaporator drain clear, and use recirculate sparingly to avoid overloading the filter.
• DIY quick steps: drop the glovebox, slide out the tray, note the airflow arrow, vacuum the housing, fit the new filter, refit — no special reset needed.

Rolling the cabin filter into the Outlander’s regular servicing keeps the interior air fresher, helps the HVAC run efficiently, and makes daily drives a bit more comfortable, whether it’s the school run or a long run down the coast.

Popular questions about the 2020 Mitsubishi Outlander cabin filter

Where is the cabin filter located?
It’s mounted behind the glovebox. Lower the glovebox by releasing the side stops, then slide out the rectangular filter tray from the HVAC unit. Swap the element, ensuring the airflow arrow points the right way, and refit.

How often should it be replaced in Australia or New Zealand?
Have it inspected annually (around 10,000–15,000 km) and plan to replace it every 15,000–30,000 km or 1–2 years. Dusty roads, urban pollution, heavy pollen or smoke exposure warrant earlier changes, and a carbon filter is a good upgrade for odours and fumes.

What part numbers fit a 2020 Outlander?
Genuine Mitsubishi cabin filter numbers commonly used include 7803A006 (or its supersession). In AU/NZ, a well-known aftermarket equivalent is Ryco RCA164P. Always confirm fitment by VIN or build code (ZJ/ZK/ZL) when ordering.
