• Brand new and high quality • High flow air filter can reduce the engine air intake resistance, while increasing the engine intake air amount per unit time and volumetric efficiency. • If the mushroom head open, constructed from the arc bracket section can be clearly seen funnel form. • This design makes the medial head of mushrooms produced vacuum, can be forced to inhale air, so the sector area completely not wastes, let the actual intake area of change. • Filter cage allows for 30% more intake surface area • Aluminum back plate for added strength • Sealing ring reduces contaminants from entering engine • 3 Layer, triple density dry filter element • 16 Inner Frames • Iron on the bottom
