Should the cotton pad be retained when using a fuel-saving pad?

[LaCody]

It is not necessary to retain the cotton pad when using a fuel-saving pad. The fuel-saving pad is placed inside the air filter element in the engine compartment to increase the air intake of the engine's intake manifold, thereby achieving the purpose of saving fuel consumption. Vehicle condition: In addition to paying attention to car cleanliness, more attention should be paid to the condition of the car, with regular maintenance and timely repairs. Driving habits: Poor driving habits often waste fuel invisibly. For example, carrying too much unnecessary weight in the vehicle, opening windows during high-speed driving, sudden acceleration and deceleration, etc., can all lead to increased fuel consumption. Impact of driving roads: Driving in urban road conditions consumes 20% more fuel than driving on a test track. The main reasons are frequent starts, stops at traffic lights, gear shifting, acceleration and deceleration, etc., which result in higher fuel consumption.
