Air Filters in Depth

Whether you're driving a car or truck in the Nissan lineup, an SUV, or a van, your vehicle has two kinds. They both trap infiltrates -- dirt, sand, road debris, mold spores, pollen, other allergens, you name it -- and keep them out of the motor, off its parts, and away from the heater and air conditioner. They do so with either a cotton, synthetic paper, metal, or foam medium, the shape of which is either circular, cylindrical, or flat. Their pleating helps better trap pollutants. Some media are even semi-permanent, meaning you can clean the filter out many times before you'll need to replace it.

One type is the engine filter, which helps remove crud before it can get into the air intake. The other type is the cabin filter, which helps keep it out of the ducts and off the vents. In a way, this is much like how fuel filters and oil filters work for fuel systems and engine parts, respectively.

Either kind can go bad, unfortunately, but luckily, there are symptoms to warn you that's happening. They include clogs (and resulting obstructed airflow), worn or damaged media, a Check Engine light or other warnings on the dash, plus black exhaust smoke, engine misfires, power loss, unusual engine noises, and trouble speeding up. You may also notice worsening fuel economy, along with whistling and other abnormal sounds coming from the vents, and a dirty or stale smell in the cabin.

See any of these, and you should inspect and, if necessary, replace your air filters. Otherwise, take care of that every 12,000 to 15,000 miles, and no more than every 30,000 miles -- namely, once a year. For more info, consult the air filter maintenance schedule in your owner's manual.

Before you order new ones, though, make sure they're genuine. Nissan makes them guaranteed compatible with the model you drive. That's a promise you won't always get from aftermarket air filters.
