If there were to be some sort of malfunction with the sensors, then the engines performance would be diminished. Once an air filter gets clogged, it will limit the amount of air that can get into the internal combustion chamber. After the ignition coil sends an electrical signal to the spark plugs, they transmit that signal to the combustion chamber so that its air & fuel mixture can be ignited by an electric spark. The sooner the exhaust excretes these gases, the sooner the engine can restart combustion. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()).
