Parts for your 2008 Nissan Navara-Cabin filter

2008 Nissan Navara cabin filter

For the 2008 Nissan Navara (D40 platform), a cabin air (in‑cabin micro) filter is supported by the HVAC design. Nissan’s D40 Service Manual refers to an “in‑cabin microfilter” within the Heater & Air Conditioning (HAC) section, and the Nissan Electronic Parts Catalogue lists a microfilter for D40 models (common P/Ns include 27277‑EB70A and 27277‑EB30A, market/build dependent). On many AU/NZ 2008 Navaras the filter element wasn’t factory‑fitted, but the housing and access cover behind the glovebox are there, so a filter can be installed and serviced like any other. That makes the cabin filter relevant to the 2008 Navara even if the original vehicle arrived without the element.

Fitted to a 2008 Navara, the cabin filter’s job is simple: clean the air coming through the vents so the driver and passengers aren’t breathing in dust, pollen, soot, and road grime. It also helps keep the evaporator core cleaner, which maintains airflow, demist performance, and keeps funky odours at bay. In Aussie and Kiwi conditions—think red dust, coastal salt air, and seasonal pollen—a decent cabin filter makes the cab noticeably fresher, especially on long drives or when towing.

For servicing, it’s a quick DIY behind the glovebox. Drop the glovebox, pop off the small rectangular cover on the blower case, and slide out the old element (or slot a new one in if there wasn’t one to begin with). Airflow arrows on the filter should face the correct direction—usually downwards. Take care not to drop leaves into the fan.

How often? A good rule of thumb is every 12 months or 15,000 km, whichever comes first. If the ute spends time on dirt roads, in the high country, or on farm tracks, check it at 6 months. Symptoms of a clogged filter include weak airflow even on high fan, slow demisting, a musty whiff, or extra fan noise.

There are two main types: standard particulate and activated‑carbon. The carbon style helps with fumes and odours—handy if the Navara often sits in traffic or works around diesels. Whichever way they go, choosing a quality brand and sticking to timely replacement keeps the HVAC happy and the cab air tidy.

• Recommended replacement: 12 months/15,000 km, earlier in dusty use.
• Signs it’s due: reduced airflow, foggy windows, musty smell, louder fan.
• Fitment note: some 2008 D40s weren’t factory‑fitted, the slot and cover are present for easy retrofit.

Popular questions

Does a 2008 Navara actually have a cabin filter from factory?
Many AU/NZ 2008 D40s didn’t leave the factory with the element installed, but the HVAC housing includes the filter slot and access cover. That means a filter can be fitted in minutes and then serviced normally thereafter.

How often should the cabin filter be replaced on a 2008 Navara?
Plan on every 12 months or 15,000 km. If the ute sees lots of dust or bush tracks, check it at about 6 months. Replace sooner if airflow drops, the windscreen demists slowly, or there’s a musty smell.

What part fits the 2008 D40?
Nissan commonly lists 27277‑EB70A (some builds use 27277‑EB30A). Many aftermarket brands offer a two‑piece element for the D40 housing. It’s best to confirm by VIN as Thai‑ and Spain‑built vehicles can differ slightly.
