Mishimoto Performance Charge Pipe Kit — B58
Mishimoto performance charge pipe for the B58 — kills the OEM plastic charge-pipe failure point and flows noticeably better. The factory plastic pipe splits and pops clamps under boost; this is the aluminum replacement.
What it is
Two mandrel-bent 3" aluminum charge pipes with CNC-machined adapters and a steel-wire-reinforced 5-layer silicone coupler (won't balloon under boost). Mishimoto rates it up to 42% less restrictive than stock. Transfer the OEM O-rings and spring clip from the stock pipe at install. Available in micro-wrinkle black or wrinkle red.
Where it fits
Induction-side hardware on a B58 Stage 2 build — we tune to the supporting mods.
