By replacing it with a normal air filter, the suction efficiency improves, and even when it is mounted on a normal engine, it is possible to increase the output over the entire range from low rotation to high rotation. 
Since the insufficient inhalation of the normal filter is eliminated, we can withdraw further output from our car parts equipped with engine parts. 
Since the normal air cleaner box is used as it is, there is no problem of intake noise and rainy weather, you can use it just like normal. 
Two kinds of filters of coarse and detailed are attached to this product.
 
■ Notes
Simultaneous installation of FI CON (injection controller) is not necessary when using this product for a normal engine.
