Turbo Inlet Pipe – Mitsubishi Evolution 4 / 5 / 6 (CP9A)

Performance Turbo Inlet Pipe – Mitsubishi Evolution 4 / 5 / 6 (CP9A)

Improve turbocharger efficiency and airflow with the Speedin Engineering Performance Turbo Inlet Pipe for the Mitsubishi Evolution 4, 5, and 6. Unlike traditional silicone replacements, this inlet is a purpose-engineered component designed from the ground up to optimize airflow into the turbocharger.

The inlet features a carefully shaped internal flow path and engineered surface texturing to control the boundary layer and reduce turbulence as air enters the compressor. This results in smoother airflow and improved efficiency compared to restrictive factory components.

Manufactured from PA6 carbon fiber–infused nylon, the inlet offers excellent heat resistance, rigidity, and durability while maintaining a lightweight design suitable for high-performance engine bays.

The inlet can be configured to suit different builds with optional BPV(bypass valve)/BOV(blow off valve) return ports and 2.5-inch or 3-inch turbo inlet connections, allowing compatibility with both factory and upgraded turbo setups.
