Parts for your 2015 Mitsubishi Lancer-Cabin filter

2015 Mitsubishi Lancer cabin filter: what it does, where it is, and when to change it

Technical sources confirm the 2015 Mitsubishi Lancer is designed to use a cabin (air conditioner) filter. The Mitsubishi Lancer CJ/CY service manual details removal/installation of the air conditioning filter behind the glovebox, the owner’s handbook lists it as a service item, and Mitsubishi’s parts catalogue (EPC/ASA) shows an OEM “Filter, Air Conditioner” commonly referenced under part number 7803A006 for this series. Plenty of professional fitment guides also show the same location and procedure, so it’s a standard service component on a 2015 Lancer.

In day-to-day driving, the cabin filter scrubs outside air before it hits the vents, catching dust, pollen and road grime, and helping reduce odours. That keeps the Lancer’s HVAC system breathing freely and makes life nicer for hay fever sufferers. It also protects the evaporator core from leaf litter and muck that can lead to musty smells and reduced airflow.

For Aussie and Kiwi conditions, a sensible replacement interval is every 12 months or about 15,000 km, and sooner if the car sees dusty roads, bushfire smoke, coastal salt air, or lots of city stop‑start. Typical signs it’s due include weak fan flow, a musty whiff with the A/C on, foggy windows that clear slowly, or the blower working harder than usual.

Inspection and replacement are quick. Drop the glovebox, release the side stops, pop the filter cover off the HVAC case and slide the old element out. Note the airflow arrow and match it on the new filter. Avoid shaking debris into the blower, a small vacuum on the housing lip helps. Don’t wash the old element—paper media loses structure—and don’t run without a filter, as debris can foul the evaporator. Choose a quality pollen or activated‑carbon element, carbon is great if odours or fumes are a bother.

As part of regular servicing, it’s smart to: check the filter each service, replace at least annually, and keep the cowl area under the windscreen free of leaves. A fresh filter keeps the Lancer’s climate control efficient, the glass clear, and the cabin air crisp—too easy.

• Recommended replacement: every 12 months/15,000 km (shorter in dusty or smoky conditions)
• Location: behind the glovebox, in the HVAC case
• Tip: align airflow arrows, consider activated carbon for better odour control

Popular questions about 2015 Mitsubishi Lancer cabin filters

Does a 2015 Mitsubishi Lancer have a cabin filter and where is it?

Yes. The 2015 Lancer uses a cabin (A/C) filter located behind the glovebox. Drop the glovebox, release the side stops, open the rectangular cover on the HVAC case, and slide the filter out. It’s a 10–20 minute job for most owners or any workshop during a routine service.

How often should the cabin filter be replaced in Australia or New Zealand?

Plan on every 12 months or around 15,000 km. If you drive on unsealed roads, in heavy traffic, through smoke or pollen season, or park under trees, shorten the interval. A quick check each service helps catch clogging before airflow drops.

Will driving without a cabin filter harm the car?

It won’t stop the car, but it’s not a good idea. Debris can cake on the evaporator, cause musty odours, strain the blower motor, and reduce demisting performance. Keeping a proper filter fitted protects the HVAC hardware and keeps the cabin healthy.
