From the diffuser, the higher pressure mixture is led into the ______ manifold and then to the ______.

• A. Exhaust manifold; cylinders.
• B. Induction manifold; inlet ports.
• C. Throttle body; plenum.
• D. Turbocharger housing; exhaust ports.

Answer: (B)

The main idea here is how boosted air is distributed into the engine. After the diffuser, the high-pressure air is sent into the induction manifold, which acts as a central distribution chamber that splits the charged flow to each cylinder. From there, the air travels through the inlet ports in the cylinder head and into the combustion chamber. This sequence—induction (intake) manifold followed by the inlet ports—lets each cylinder receive the charged air evenly, which is essential for efficient combustion. The other options don’t fit this flow: the exhaust manifold handles exhaust gases, not intake; the throttle body and plenum are earlier stages of the intake path and don’t represent the direct distribution to the cylinders as described; and the turbocharger housing is related to the exhaust-driven turbine side rather than feeding the intake.
