摘要

The manifold has two air filter bins (1, 2) with induction pipes (3, 4) having different lengths, and connected with a switching unit (5). The switching unit is switched based on engine speed/speed of a vehicle. The pipes are fastened on one side of the unit in Y-form, and another side of the unit is connected with an internal combustion engine (6). The diameter of the pipes varies by +, - 30 percent from the diameter of the unit.
