Intake manifolds are a crucial component of the engine's air intake system. It is responsible for distributing the air-fuel mixture to the individual cylinders for combustion. The intake manifold is typically made of cast aluminum or plastic & is designed with a series of passages or runners that connect the throttle body or carburetor to the intake ports of each cylinder. The primary function of the intake manifold is to optimize airflow & promote efficient combustion. It achieves this by controlling the air velocity & distribution to each cylinder, ensuring a balanced air-fuel mixture for optimal performance & fuel efficiency. Some intake manifolds are designed with variable length runners or intake tuning mechanisms to enhance low-end torque or high-end power, depending on the engine's needs. Upgrading the intake manifold can be a popular performance modification, as it can improve airflow & increase engine power. However, it's important to consider other supporting modifications & tune the engine accordingly for optimal results.
