Question

Quizplus · Accepted Answer

Technician B is correct because some intake manifolds are indeed constructed in two parts, upper and lower, to improve the engine's performance and facilitate easier repair or modification. Technician A is incorrect because intake manifolds can also be made from materials other than metal, such as plastic or composite materials, to reduce weight and cost.
