Both statements are correct. Some intake manifolds are indeed made of plastic to reduce weight and cost, and improve thermal management. Additionally, it's common for intake manifolds to be constructed in two parts (upper and lower sections) to facilitate manufacturing and sometimes to integrate different functionalities or materials in each section.
