Dinan
Dinan Carbon Fiber Turbo Inlet Pipe – B58 Engine
OVERVIEW
Turbo inlet pipes serve two distinct purposes, and Dinan delivers on both. On the performance side, an optimized inlet lets the turbo ingest more air through an unobstructed, larger-volume flow path for improved efficiency and responsiveness. On the visceral side, it unlocks the induction sound the factory setup was designed to suppress. The Dinan Carbon Fiber Turbo Inlet Pipe replaces the weak, failure-prone plastic factory inlet with a durable carbon fiber unit, removes the internal resonators responsible for flow restriction and turbulence, and enlarges the internal diameter for a more uniform, less restrictive path to the turbo — all while amplifying the turbo's induction soundtrack.
SPECS
- Carbon fiber construction — direct replacement for the failure-prone factory plastic inlet
- Average 7.7–12.5% larger internal diameter throughout (maximum cross-sectional area allowed)
- Eliminates the factory sound resonator for increased turbo vocalization
- Increased turbo efficiency and reliability from unimpeded, uniform airflow
- CNC-machined fittings ensure precise fitment and direct bolt-on installation
- Quick and easy installation — no permanent modification
- Legal under EPA Tampering Policy for on-street use in states that accept EPA provisions; not legal for sale or use in California pending CARB certification
PARTS INCLUDED
- 1x carbon fiber turbo inlet pipe
TECH RESOURCES
- Installation Instructions (PDF)
- Only compatible with 2020–2025 (LCI) X3/X4 M40i model years — pre-LCI (2018–2019) models use a different configuration
- LCI X3/X4 M40i owners must also purchase the Inlet Fit Kit (D763-0101) to mate this turbo inlet to either the factory or Dinan intake system — it will not connect without it
