What is this about changing the air filter to make my car faster and more fuel efficient?

what is the downside to installing this other air filter?|||I%26#039;m 68 and a female but I%26#039;ve taken care of my vehicles for a long time. As far as I%26#039;m concerned there is NO downside to changing your air filter. It is able to intake more oxygen, therefore running more efficiently. I check mine everytime I have the oil changed. Sometimes you can just %26quot;bang%26quot; the dirty residue out of them. It is very importanr to keep a clean one. Hope this helps!! I know it%26#039;s not really a technical answer but one with much experience! :-)

it will give slightly better gas milage with a proper oil change|||it like you, you eat and you need bathroom also.|||When your air filter is clean, your car gets a steady stream of fresh clean air to mix with the fuel as it goes into the engine. When the air filter is dirty, the flow of air is reduced and there are more impurities in the air. The net result is reduced fuel efficiency (and perhaps performance).





An filter designed to improve the flow of air could result in a small improvement in fuel economy and/or performance. But the improvement may not be great enough to pay for the filter over the long run.





Also be careful of having your air filter changed at a lube and oil shop. These shops push air filters because they are low cost with high mark-up. You should always inspect your air filter by holding it up toward the sun - if you can see daylight coming through, then the filter doesn%26#039;t need to be changed. Your filter only needs to be changed once a year and you might be better off stopping at an auto parts store to buy a filter and change it yourself.|||careful, if you are only changing the filter itself and replacing it with an oil charged filter such as a k%26amp;n you have to go easy when you clean and re oil it. I see lots of them cause problems with the mass air flow sensor due to over oiling.|||your car needs air to operate correctly.like the human body,you need air to live.the engine is like a air pump.the faster air flows through it the better it operate.you need to change the air filter every 3 to 6 months to keep your car running well if the filter were to get cogged your car won%26#039;t run
