Intake manifold

Intake manifolds were components on starships.

In 2153, Commander Tucker advised against increasing speed in the thermobaric cloud perimeter of the Delphic Expanse, as the intake manifolds of the were having trouble processing the gasses. 

Later that year, when Enterprise entered a polaric field in the Expanse, nucleonic particles flooded the intake manifolds and disabled the ship's propulsion systems. 

Still later in 2153, Captain Jonathan Archer released warp plasma from the cargo vessel he was flying into the intake manifolds of a Xindi-Insectoid ship, which overheated their engines. 

In 2155, Commander Kelby ordered that the intake manifolds be modified to process cometary debris, as Enterprise would be using Comet Burke as cover to covertly approach Mars while sending a team to infiltrate John Frederick Paxton's secret base.
