Both terms share their roots in the Classical Latin centenarius, meaning hundredlike, but the quintal has a convoluted etymology: It became Late Latin centenarium pondus, then in succession, Byzantine Greek ÎºÎµÎ½ÏÎ·Î½Î¬ÏÎ¹Î¿Î½ (kentenarion) and Arabic qintar ÙÙØ·Ø§Ø±.
If your air filter gets too dirty or clogged, your engine won't be able to suck enough air into the combustion chambers. The engine will then run rich (i.e., too much gas and not enough air). When this happens, your car will lose power and run roughly. Your Check Engine light also may come on. If you really neglect the air filter for a long time, your car may stop running altogether. While permanent damage is unlikely, it is possible. If an air filter were sufficiently dirty and damaged, it could allow harmful, abrasive contaminants into the combustion chamber.
Air filters in most engines are easy to access and so you can tell when it needs a replacement by just simply finding the black areas on the section through which the air enters. But it is more recommended to change the filters for every 30,000 miles (48280 km). Bad effects: A clogged air filter won't significantly affect fuel economy, but it can hurt acceleration by 6% to 11%. Acceleration is harder to measure than fuel economy, so you may not notice a gradual performance loss.
