Parts for your 2017 Mitsubishi Asx-Air filter

2017 Mitsubishi ASX air filter — what it does and how to look after it

Yes, the 2017 Mitsubishi ASX is fitted with an engine air filter. It sits inside the air cleaner housing in the engine bay and is part of the standard intake system on both petrol and diesel variants. This is confirmed by factory documentation and parts catalogues, including the 2017 ASX Owner’s Manual (air cleaner/maintenance section), the Mitsubishi ASX workshop manual intake section, Mitsubishi’s Service and Warranty schedule, and mainstream filter catalogues that list an engine air filter specifically for the 2017 ASX.

The air filter’s job is simple but critical: it cleans the air before it reaches the engine, trapping dust, sand, pollen and other nasties so the cylinders only ingest clean air. That helps the ASX breathe properly, keeps fuel economy on point, and protects the mass airflow sensor and turbo (on diesel models) from abrasive particles. A healthy filter supports smooth acceleration and stable idle, while a choked one can cause sluggish performance and higher fuel use.

As part of regular servicing, the filter should be inspected at each service and replaced at the interval recommended in the service schedule, or earlier if the element is dirty. In Aussie and Kiwi conditions—especially if driving on gravel roads, farm tracks or coastal areas—it’s smart to check more often. A practical rule many workshops follow is to inspect around every 15,000 km and replace roughly every 30,000 km or sooner if it looks clogged, but always follow the service booklet for your exact engine and usage.

Good practice under the bonnet includes making sure the airbox seals are seated properly, the clips are fully latched, and the intake snorkel is clear of debris. If using a reusable performance filter, go easy on any oiling process—over‑oiling can foul the MAF sensor and set a fault light. After any off‑road or dusty trip, a quick visual check is cheap insurance.

• Warning signs it’s time: noticeable drop in power, thirstier fuel consumption, darker or heavily dusty filter media, or whistling intake noises.
• Tip: Always fit the element in the correct orientation and avoid tapping or blowing high‑pressure air through paper media, which can damage it.

Popular questions

How often should the 2017 ASX engine air filter be replaced?

Most owners will be fine inspecting at every service and replacing about every 30,000 km or two years. If the ASX works in dusty regions or regularly hits unsealed roads, shorten that interval. Always follow the Service and Warranty booklet for your specific engine.

What are the symptoms of a clogged air filter on an ASX?

Common signs include dull acceleration, a slight increase in fuel use, darker or dusty filter media, and sometimes a rougher idle. In extreme cases, the MAF sensor may report issues. A quick visual check of the element can confirm if it’s due.

Is the cabin (pollen) filter the same as the engine air filter?

No. The engine air filter protects the engine, the cabin filter cleans the air entering the cabin via the HVAC system and is usually located behind the glovebox. Both are service items, but they’re different parts with different jobs.
