Description
Maximize airflow and turbocharger performance with the RK-Tunes G-Series B58 Front Mount Intake System. Designed and engineered in-house, this premium intake upgrade features a full 3.5-inch airflow path and high-strength 5-ply wire-reinforced silicone construction, delivering superior airflow capacity compared to factory and competing aftermarket intake systems.
Built specifically for BMW's latest-generation B58-powered vehicles, the RK-Tunes intake maintains a large internal diameter throughout the intake tract to reduce restriction and improve turbocharger efficiency. The reinforced silicone design prevents the intake from collapsing under high boost while providing the flexibility needed for a precise fit and straightforward installation.
In addition to improved airflow, the intake enhances turbo spool and induction sound, allowing drivers to hear the B58's turbocharger more clearly while supporting stock and upgraded turbocharger applications. Installation is simplified with a design that requires no bumper removal and no removal of the factory V-brace.
