In addition to monitoring the engine's air intake, an engine's output will indicate problems with the air filter. If potent fuel smells and dark exhaust are coming from the engine, then it's likely that the air filter is experiencing issues and needs to be replaced.
Replacing a dirty, clogged air filter with a clean one brings immediate improvements. Your engine sound will change noticeably, with less straining and raspy noises from under the hood.
Black smoke from the exhaust is also an obvious sign that the air filter is dirty and needs to be replaced. The smoke happens when there isn't enough oxygen getting into the engine, so the fuel doesn't burn properly and creates black smoke instead.
A worn filter, especially the engine air filter, can cause numerous issues, including decreasing the effectiveness of your catalytic converter.
A dirty engine air filter will block the amount of oxygen coming into your vehicle's engine. That will reduce engine efficiency and rob you of the max power that you can get from your vehicle.
Filters gather dirt, and if they aren't replaced on a regular basis, the filter might get clogged. Many things will happen when you need to replace your vehicle's engine air filter. Having a filthy or clogged air filter might cause your car to struggle to accelerate at a typical rate.
If you're noticing sluggish engine performance, reduced acceleration, a smell of rotten eggs or sulfur from the exhaust, dark exhaust smoke, or extreme heat coming from under the vehicle, these are symptoms of a clogged Catalytic Converter, and it should be repaired soon.
A dirty air filter can cause your vehicle to throw a Check Engine code. During this instance, the Check Engine Light of your vehicle will turn on. The light turns on because your vehicle is sensing that its engine isn't receiving enough air.
An unhealthy air filter can cause your engine to sputter or make popping noises.
Billowing black smoke is generally a sign that the fuel-air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
Simply replacing your engine air filter can increase horsepower and, in some cases, even improve mileage.

Often ventilation systems such as these will insert HEPA filters or ULPA filters at their exhaust site as these remove up to 99% of microscopic bacteria, diseases and allergens which pose serious health risks.
For an even louder sound, add a cold-air intake to your turbo; since cold air has more oxygen than warm air, cold-air intakes produce larger combustion in your engine. Alternatively, add a turbo whistle to your exhaust pipe for a similar effect to a turbocharger.
Catalytic converters make a sound if they start to fail. It could sound like a loud rattle or like the engine isn't moving as smoothly as it normally does. This can be a sign of an excessive amount of sulfur in the catalytic converter's exhaust system, which can render it ineffective.
If your converter has been stolen, you're likely to notice right away: Without the converter, your car will be much noisier than usual. Most cars will run without a catalytic converter, though it's inadvisable to do so for longer than necessary.
When it comes to the air filter, a bad air filter can make a funny and loud noise to disturb you while driving your car.
You may notice a decrease in power, sluggish acceleration, or a general lack of responsiveness from your vehicle. Most vehicles require 14.7 parts of air to 1 part of fuel. If you limit the air, the air/fuel mixture in the chamber won't be correct. The engine will lose power, especially on acceleration.
One of the most common causes for a car jerking is that spark plugs are old or worn out, meaning that they can cause incomplete combustion. As a result, this leads to a car engine misfiring and jerking during acceleration or when travelling at low speeds.
In this Maintenance Minute, Andrew Markel talks about how and why rough transmission shifts can be caused by the air filter and what some of the likely culprits are.
How much does it cost to replace an air filter? Replacing your car's air filter can cost anywhere from $20-$50, depending on the type of vehicle you have and the quality of filter. A high-quality filter will ensure better airflow, engine performance, and fuel economy — so it's worth investing in a reliable one!
Check Engine Light Comes On
The CEL warning light will turn on when the engine is not getting an adequate supply of air. If you have noticed other symptoms like lackluster acceleration or reduced fuel economy, then that light could very well be telling you the air filter might be clogged and needs to be changed.
