2001 Mitsubishi Pajero Air Filter — What It Does and When To Replace It

Based on technical references including the Mitsubishi Pajero NM/NP Workshop Manual (2000–2002), the Mitsubishi Service and Warranty Schedule for Australia/NZ, and major parts catalogues (Mitsubishi ASA, Ryco Filters, Mann‑Filter, Sakura), the 2001 Mitsubishi Pajero is fitted with a replaceable engine air filter (often called the air cleaner element). So yes—an air filter is absolutely relevant and used on this model.

On a 2001 Pajero—whether it’s the petrol V6 or the 3.2 Di‑D turbo‑diesel—the air filter’s job is to trap dust, sand, and grime before it reaches the intake, cylinders, and sensors. Clean air means better combustion, stronger performance, improved fuel economy, and less engine wear. Given how many Pajeros spend time on corrugations and farm tracks, that filter does some serious heavy lifting under Aussie and Kiwi conditions.

As part of routine servicing, the filter should be inspected regularly and replaced at sensible intervals. Factory guidance and local service schedules typically call for inspections every 10,000–15,000 km (or 12 months) and replacement around 30,000–40,000 km. If the vehicle sees a lot of gravel, beach work, bush tracks, or towing in dusty heat, shorten those intervals—dust is the enemy.

• Typical intervals: inspect 10,000–15,000 km, replace 30,000–40,000 km (earlier in dusty use).
• Signs it’s due: noticeable loss of power, rougher running, thirstier fuel use, darker/dirty pleats, louder induction roar.
• Quick tips: open the air box clips, lift the lid, and remove the element. Don’t wash a paper filter. Avoid blasting with high‑pressure air as it can tear the media. Wipe out the air box with a clean, dry cloth, seat the new filter evenly, and refit the lid without pinching the seal.

A healthy air filter also protects intake sensors and turbo compressor blades (diesel models) from abrasive dust. Keeping it fresh helps the Pajero breathe easily on long highway runs and during steep, low‑range climbs.

Location wise, the air box sits in the engine bay under the bonnet—look for the black plastic housing with metal clips on the guard side. Replacement is quick, satisfying driveway maintenance that pays off every kilometre.

FAQs

Where is the air filter on a 2001 Mitsubishi Pajero?
It’s in the air box under the bonnet, typically on the front corner/guard side. Pop the metal clips, lift the lid, and the panel element lifts straight out. No special tools needed.

How often should the air filter be replaced?
Check it every 10,000–15,000 km or yearly, and replace about every 30,000–40,000 km. In dusty Aussie or Kiwi conditions, change it sooner to keep performance and economy on point.

Can a reusable oiled filter be fitted?
It can, but use caution—over‑oiling can contaminate intake sensors. For mixed touring and off‑road, a quality paper element is reliable, affordable, and well‑matched to the Pajero’s needs.
