Air Filters

How Many and What Kinds of Air Filters are There?

Most Nissan models have two -- one for the engine and one for the cabin.

What Do They Do?

The engine air filter keeps everything from dirt and road debris to sand from the shoulder, even insects, out of the air intake. In doing so, it keeps them out of the rest of the motor. The cabin air filter, however, keeps pollen, mold spores, and all sorts of other allergens out of the ducts in the heating and air conditioning systems. That way, they stay off the vents into the interior.

What are They Made of?

Those that aren't synthetic paper or foam are usually made of cotton or metal. The media are often pleated, making them better at trapping things. Their shapes range from flat and circular to cylindrical. Some, the semi-permanent kind, you can even wash and reuse many times before they require replacement.

What are the Signs They're Going Bad?

• Clogs (airflow obstructions)
• Worn or damaged filter media
• Worsening fuel economy
• Black exhaust smoke
• The Check Engine and/or other warning lights illuminating on the dash
• Engine misfires
• Loss of engine power
• Other strange engine noises
• Having trouble accelerating
• Whistling or other weird sounds coming from the vents in-cabin
• A dirty or stale smell on the interior

When Should I Replace Them?

Every 12,000 to 15,000 miles, or every 30,000 miles at most. That's once a year. Otherwise, do so when you see the above-mentioned symptoms.

For more info on what to do and further instructions on when to do it, check your owner's manual's maintenance schedule. Before you order new air filters, however, make sure they're the genuine article.

Why Buy Genuine OEM?

Nissan manufactures them guaranteed compatible with the car, truck, SUV, or van you drive. The aftermarket for air filters can't always promise the same.
