What happen if I do not change the dirty air filter in the car?

Actually, how does the air filter affect the car performance and gas consumption, etc?

if the air filter is dirty, less air gets into the engine and causes higher gas consumption to a car. gas and air mix in almost equal parts...the spark pulg ignites the gas and pushes the pistons up and down. if there is not enough air, then there is more gas than normal and more waste of gas and it would not run efficiently. if your strapped for money to buy a new one, just use air from a compressor at the gas station or buy air cans to clean it out.

poor gas milage and preformance,spend the $10 to $20,it pays off!
It will suffocate your engine and will start to run poorly and get very bad fuel economy, eventually it will start stalling and loose it's power. Air filters are cheap and easy to replace so it would be a very good idea for maximum performance get a new one asap
as the air filter gets dirty it hinders the flow of air into your engine. causing the fuel air mixture to be off....the plugs will become fouled and your miles per gallon will go down...you will feel a difference in how the engine performs when you accelerate. and the richer mixture can cause your catalytic converter to burn out because of unburnt gas in the exhaust.



so spending the money needed to put a new air filter in your car is a lot cheaper in the long run then running with a dirty one.....



bye you air filter when it is on sale and not wait till you need it and it will cost you less to replace it.
Your engine will be 'air-starved.' If you can't pay to replace it, remove it and clean it. Here are instructions I found at the website below - I hope it helps.



Can I service a paper, disposable air filter myself for longer service?



Yes. Remove the filter and cover the intake to prevent foreign objects from entering it during the air filter service. Move away from the vehicle and tap the filter gently on the ground to knock out large pieces and loosen small pieces/dust. The best thing to do now is to use an air blower (at about 40-60 psi) to blow out from the center of the air filter 鈥?forcing the air in the opposite direction of flow when it's installed. If you can't do that, use a shop style vacuum to get the dust out but use the nozzle on the outside of the filter 鈥?from the direction air flows when it's installed. Note: a small, soft brush is also excellent to use during this process.
The air filter is the only route for the air required for combustion to follow. If the filter becomes blocked with dirt, less air will flow to the engine but the engine will still have the same displacement and as a result will draw more fuel. Also the fuel air ratio is very important, if you have to much fuel it will not burn completely and will increase your fuel economy.
as eveyone else has said, you will get less air, but not only that if even a small amout of dirt (1 grain of sand size and smaller) gets through it can completly block up your carby (if you have one) even if your car is fuel injected the dirt in the air getting in can have a sand paper affect on your cylinder walls. MAIN POINT get a cheap air filter $10-$20 or end up having to posibly spend thousands on your engine
dirty filters equal poor perormance engine will be starving for air your gas mileage will drop considerably. Eventually it will result in excessive engine wear due to air fuel mixture spark plugs will wear out sooner etc. etc. chage it as soon as you can or try blowing it out with compressed air until you can.
