Why switch to alloy boost pipes

The factory S58 pressure pipes use a plastic collector and rubber hoses that can become a weak link, especially on tuned cars. Heat cycling and elevated manifold pressure often lead to splits, loose couplers and limp mode. The Mishimoto setup strengthens this critical section of the intake tract with a cast aluminium turbo merge and robust silicone hosework that keeps the seal under load while promoting better airflow to the intercooler.

Built for flow, made for durability

By refining the transitions from each compressor outlet into the intercooler feed, this boost tube kit minimises turbulence and restriction. The multi‑layer silicone delivers the flexibility needed for engine movement yet resists heat and pressure far better than OE rubber. With 27 percent less restriction than the standard assembly, it is the ideal foundation for power increases and repeatable performance.
