Air Filters

It's important to replace your air filters often, since they protect important systems from airborne contaminants and the harm they can cause. In that way, they serve the same purpose as your fuel filter and oil filter.

Your car, truck, van, or pickup most likely has two air filters in place. One is for your engine. This filter is located near the air intake, where it can immediately capture those pollutants before they can get into the engine parts. Without this filter, your engine wouldn't perform nearly as efficiently.

The other air filter is for your HVAC system. Typically, it's found behind your glove compartment, though it can also be placed underneath the front cowling on the passenger side of your vehicle. It traps allergens and irritants before they make their way into the cabin via the air vents. Without it, you'd be breathing in unclean air.

Unfortunately, your air filters will either degrade with age or get too clogged up to allow unrestricted airflow. When that happens, they need to be replaced. Fortunately, there are signs of this happening:

• Your "Check Engine" light comes on
• The engine starts misfiring
• You notice impaired throttle response
• You hear unusual engine noises
• Your engine power is reduced
• Fuel economy suffers
• Your cabin sells musty
• There's a whistling sound coming from the air vents
• Your emissions increase
