Mishimoto intercooler pipe kit for 2016–2021 Honda Civic 1.5T and 2017–2020 Civic Si replaces restrictive plastic piping with mandrel‑bent aluminum and larger diameter tubes for improved flow. Pipes increase side diameters from 42mm to 55mm (~30% larger), reduce bend angles, and use five‑layer silicone couplers. When paired with Mishimoto intercooler, gains are noted; available in wrinkle black or Rallye red.
