Car intake system includes air cleaner, intake manifold, into the valve body. The air filter air filter impurities, flows through the air flow through the inlet into the intake manifold, exhaust gas mixed with the nozzle to form a proper proportion of oil and gas market, into the cylinder by the valve into the Ignition within the combustion to produce power. Modern cars are mainly Variable Intake System intake system. Variable intake system mainly consists of VVT (variable valve timing), CVVT (continuously variable valve timing), VVT-i (variable timing electronic), i-VTEC (Variable valve lift e) The four Species.
    Based car intake system modification is to improve the engines'volumetric efficiency', to achieve this goal is usually initiated by the following ways:
 First, the air filter. Work is modified car intake system for the entry of high efficiency, high flow air filter filter. Dress high flow air filter can reduce the resistance of the engine air intake, while increasing the engine running into the gas per unit time and volume efficiency, fuel supply system by the air flow meter in the intake air increases, the signal sent To supply the computer (ECU), ECU will control the fuel injector spray more co-ordinated with, so that more oil into the cylinders to achieve the purpose of increasing the power output.
  Second, the inlet. Modified inlet can be divided into two talk about shapes and materials. Purpose of changing the shape of the inlet into the gas storage pressure (hard acceleration for the season to be fully opened valve suddenly) and increase the flow rate of intake, but these products often have special restrictions, that is A Model A device used in the B-car does not necessarily maximize its effect, but focus on changing the inlet is not heat-absorbing materials and light weight, the most commonly used is the carbon fiber material, it does not heat-absorbing properties , Allowing the temperature of the inlet end is not affected by the high temperature engine compartment, so that the higher the density of the intake, which increases the oxygen content per unit volume, improve engine output.The only drawback is the price sky high. Inlet is often modified to change both shape and material to receive maximum effect, and will be removed the air filter and inlet extending to the car, directly at the front in order to increase the speed increase with the inlet pressure, Increase into the air.
      Increase engine horsepower There are many ways, the easiest way is also the lowest cost of the modified car intake system.
