How does changing spark plug affects the fuel efficiency?

i have a %26#039;07 toyota corolla





pls serious answers only...





thanks so much!!!|||The spark plug introduces the initial spark that starts the fuel mixture burning, with high performance plugs, like v-fire, split fire, etc. The belief is that the enhanced spark kernel is better at propagating the flame front. In this way the fuel burns more completely and travels across the combustion chamber in a more efficient manor.


Platinum and iridium plugs are more durable, last longer and take less electricity to fire.


When the spark plug starts to erode (wear) the tips and electrode down, the electrical load needed to jump the %26quot;gap%26quot; increases, this increase in electrical load tends to wear all the components in the secondary side of the ignition system. ( cap , rotor, wires, coil). The reason so many coil packs fail, IMO.|||with an 07 it doesn%26#039;t. It matter whens you have old worn out plugs and the spark is not what is used to be. I wouldn%26#039;t bother changing your plugs..its a waste of time and money unless you need them.|||It helps burn the gas more evenly so it doesnt just burn up fast. It does help a lil bit
