The owner's manual in my 03 Impala recommends that the panel air filter be inspected every 25,000 km (15,000 miles) and replaced every 50,000 km (30,000 miles).

In comparison, my 1965 owner's and service manuals recommend inspection & cleaning every 6 months and replacement every 2 years.

Generally filter service cycles have been extended over the years, particularly when oil bath air filters, 2000 mile chassis greaseing & oil changes, and vented oil pans were discontinued. What still can be found in most car manuals is a disclaimer for operating under severe service conditions. Such as cold climate, short trips, dusty, stop & go traffic, extended idling periods, extended high speed operation, trailer pulling etc. which cuts normal maintenance interval in half.

Changing air filters & oil is highly subjective and an individual decision based on his operating conditions, and driving habits. I SWAG it with air & cabin filters, and change oil normally every 3000 – 4000 miles because of our inhospitable climate in Maine for cars six months of every year.

The BITOG Air Filtration Test seems to indicate that low-restriction cotton-gauze or foam air filters do not capture as much dirt as standard pleated paper or fiber filters.

…unless you actually want to prevent abrasive dirt entering your engine, in which case stick to real (i.e., paper) air filters. See here to cure any lingering marketeering-induced misconceptions about K&N and similar "filters". There is no increase in fuel economy or performance from these "filters" because the throttle plate, and not the air filter, is the bottleneck in the intake tract.

The right answer, technically speaking, is the measure the pressure differential across the filter. Aside from this, actual change intervals depend on the environmental conditions you operate your vehicle in.

I agree. :wink: :wink: If anything they decrease economy.
