Flame or black smoke from the exhaust pipe is an obvious sign of a dirty air filter. Performing a visual inspection is an easy way to know if an air filter needs to be changed. A new air filter is white or off-white, while a dirty air filter will appear darker with visible dirt and debris. Most automotive companies recommend changing the air filter every 10,000 to 15,000 miles or every 12 months.
However, if you normally drive in dusty or rural areas such as Scottsdale, Arizona or San Antonio, Texas, it's a good idea to have your mechanic check and change it more often, for example, every 6,000 miles. Driving in busy areas where there is a lot of traffic, including Los Angeles and Washington DC, making it stop and start more often also requires you to replace the air cleaner more often.

Air enters the engine through the air filter. Without a proper air intake, the fuel mixture will be too rich in fuel, so it will not burn properly and the engine will be deprived of the oxygen it needs. Most manufacturers recommend replacing the air filter every 12,000 miles (approximately 19,000 km) or every 12 months, whichever comes first. However, you should consider replacing your air cleaner more often if you live in an agricultural area or in any area with a lot of dust or impurities in the air.
Inadequate air supply can cause carbon deposits to build up on the engine, which will eventually activate the engine check light. If the light comes on, check the air filter to see if it needs to be replaced before performing other diagnostics. For this reason, most car manufacturers recommend changing the air filter every 12,000 miles (approximately 19,000 km) or every 12 months, whichever comes first, regardless of how dirty the air filter appears to be.

Have your mechanic scan your vehicle to locate the source of the problem as it could be as simple as replacing the air filter. But when the air filter doesn't allow enough or constant air to enter it can cause the engine to have problems accelerating. If the air filter becomes too congested during summer cooling season it can cause a lack of airflow to evaporator or cooling coils.
