Can the intake manifold of Big Dipper 1.0 be replaced with aluminum?

Aluminum can be used instead, but it is not recommended.

The casting yield of aluminum intake manifold blank is low and the processing cost is high.

The intake manifold refers to the intake pipe from the back of the carburetor or throttle body to the front of the intake port of the cylinder head. Its function is to distribute the mixture from carburetor or throttle body to the air intake of each cylinder.
