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.

With over 30 years of driving experience and having driven various car models, I must caution everyone to be careful about whether to keep the insulation pad when installing fuel-saving pads. The insulation pad is the heat-resistant material under the hood that prevents high temperatures from damaging the paint and components. Fuel-saving pads are usually additional fuel-saving devices and do not mean you can remove the original factory parts. If you remove the insulation pad, the engine heats up faster, making it easy to burn your hands in summer and affecting air conditioning efficiency. Experienced mechanics always advise checking the manual or consulting a professional shop before making any modifications—safety first. Don’t risk damaging your car just to save a little fuel; the money saved won’t cover the repair costs.

Over the years of car repair, I've helped many owners deal with such issues. I strongly recommend keeping the cotton pad. It serves for temperature reduction and protection, while the fuel-saving pad is merely an auxiliary device for fuel economy. Removing the cotton pad may cause engine overheating and damage electronic components. When the fuel-saving pad is properly installed, the cotton pad doesn't get in the way; instead, its heat insulation helps maintain stable fuel consumption. A common misconception is removing the pad to save space, but this can easily lead to short circuits or fire hazards. Remember to check the vehicle's condition before any operation, and consult professional repair services if unsure—don't risk saving small money only to spend big later.

As a novice driver with only six months of experience, the mechanic advised me not to touch the cotton pad when installing the fuel-saving mat last time. After researching, I learned that the cotton pad serves for sound insulation and heat insulation, and adding the fuel-saving mat doesn't affect its function. My friend removed his, and now his engine hood gets extremely hot, with a slight increase in fuel consumption, leading to extra monthly costs for cooling protection. My driving instructor once said that original factory designs have their reasons, and we shouldn't modify parts randomly, especially those related to temperature control—it's safer to keep them as they are.
