The modification of the air intake system is to switch to an air filter with high efficiency and large flow. Replacing the high-flow air filter can reduce the intake resistance of the engine and improve the intake volume and volumetric efficiency per unit time when the engine is running. The increase of air intake is measured by the air flow in the fuel supply system, and the signal is sent to the fuel supply computer (ECU), which will control the fuel injector to spray more gasoline to cooperate with it, so that more oil and gas (not rich) can enter the cylinder, so as to increase the horsepower output. If the filter element can't meet your needs, you can replace the whole air filter with an exposed filter element, commonly known as "mushroom head", to further reduce the air intake blockage and enhance the "vital capacity" of the engine. Turn up the exhaust-when the exhaust back pressure is reduced, the low torque will be reduced, and the engine exhaust valve will be easily burned due to ultra-high temperature.

Mushroom head-reduce intake inertia, reduce low torque, increase fuel consumption, low speed fatigue.
