Plasma manifold
From Memory Alpha, the free Star Trek reference.
A plasma manifold (also known as an EPS manifold or plasma distribution manifold) is a component that channels electro-plasma through a (warp) power distribution system in a starship or space station. The technology is based on the 21st century ion distributor. (VOY: "One Small Step") One component of the plasma manifold is a phase compensator. (DS9: "Return to Grace")
The plasma manifolds of NX class starships require an occasional purging. (ENT: "Unexpected") Klingon birds-of-prey possess more than one plasma manifold; having at least one backup manifold. (DS9: "Return to Grace") Cardassian plasma manifolds use a beta-matrix compositor. The Federation is unable to replicate this sort of technology but, however, is able to replicate replacements for their own starships. (DS9: "Empok Nor"; VOY: "One Small Step")
If a replicator power converter is crossed with the plasma manifold there is a great chance the plasma relay would explode, although this did not always happen. (DS9: "Defiant")
When Tom Paris played the Insurrection Alpha holonovel in 2373, he was slightly too eager to join Chakotay's mutiny, causing Chakotay to assign him to lubricating the warp plasma manifolds in suspicion. (VOY: "Worst Case Scenario")
