If the air filter is not checked and replaced at recommended service intervals or the vehicle is used repeatedly in a dusty environment, the air filter remains clogged with dirt. This ultimately hampers the performance of the vehicle, which is evident from a few minor as well as major signs, which are as follows:

  • fall in power
    Due to accumulation of dirt in the air filter, the engine does not get enough air. This eventually results in erratic acceleration even after consistent throttle input.

  • check engine light flashing
    When an air filter becomes clogged with dirt, an insufficient supply of air causes carbon to build up in the engine, which can trigger the check engine light.

  • Dirt visible in the air filter
    Checking the air filter is a must at every service check-up. The accumulation of dirt and dust makes the air filter appear black, changing its color from light to dark.

  • drop in fuel efficiency
    Irregular supply of air to the combustion chamber due to a clogged air filter results in excessive fuel consumption, which reduces fuel efficiency.

  • engine misfiring
    Due to carbon deposits due to poor air-fuel mixture due to a dirty air filter, soot residue starts to accumulate at the tip of the spark plug and cause misfiring in petrol engines.

  • exhaust smoke
    Black or dark brown smoke emissions from a vehicle’s exhaust pipe are also a sign of improper combustion of the air-fuel mixture, which is the result of a dirty air filter.

  • Fuel smell during startup
    If not enough air is supplied to the engine, unburned fuel is released from the engine through the exhaust pipe, resulting in the emission of a fuel odor.

  • sudden engine noise

    If an air filter becomes clogged with dirt, a lack of adequate air supply can cause a strange whistling sound, which is evident when accelerating the vehicle.
