What it does
The intake manifold carries air from the throttle body to each cylinder. Air and fuel parts decide how well the engine breathes and how cleanly it runs, so the right part restores smooth running and can support more power on a modified engine.
Installation & tips

- Intake manifold gaskets: Always new.
- Vacuum hoses: Old hoses crack when disturbed.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
