The intake manifold is a component that connects the Toyota Engine and the intake system. Its main function is to introduce air into the combustion chamber of the Toyota Engine for combustion, while regulating and distributing the flow rate and airflow direction of the air.

The design of the intake manifold can be optimized according to the needs and performance requirements of different Bare Engine. Some common design parameters include: the length of the manifold, the bending angle, the cross-sectional shape, the material and the surface treatment. Changes in these parameters will directly affect the flow, distribution and stability of the intake system, thereby affecting performance and fuel economy.

Some improved intake manifold designs can further improve performance and response. For example, the use of a variable-length intake manifold can optimize the intake efficiency at different speeds, improve power and torque, and reduce emission pollutants; the use of an intake manifold inner baffle can also increase the stability of the airflow and the amount of intake.

In short, the intake manifold is an important component in the intake system of an Toyota Engine, and its design and optimization can directly affect performance and efficiency. Therefore, when designing and selecting the intake manifold, reasonable optimization and improvement should be carried out in combination with specific needs, performance requirements and environmental conditions.
