Increase airflow to the turbochargers on your BMW M3 with the HFE High-Flow Intake System for the S58 engine. This intake system replaces the restrictive factory intake tract ahead of the turbo inlets, allowing a greater volume of cooler, less turbulent air to reach the compressors. The result is improved throttle response, enhanced turbo sound, and a stronger foundation for tuned and performance-driven builds.
⚠ IMPORTANT – MODIFICATION NOTICE
Aftermarket intake systems alter airflow characteristics and increase induction noise. ECU calibration is not required on a stock vehicle, however tuning is recommended to maximise performance benefits on modified applications.
Key Features＋
- High-Flow Intake Design: Reduces restriction before the turbocharger inlets.
- Optimised Air Path: Smoother airflow delivery to the S58 twin turbos.
- Performance Air Filters: Increased surface area for improved airflow capacity.
- Enhanced Induction Sound: More pronounced turbo spool and intake noise.
- Heat-Resistant Construction: Designed to perform in high-temperature engine bays.
- Direct-Fit System: Installs using factory mounting points with no cutting required.
Why Upgrade the S58 Intake?＋
- Improves airflow volume to the turbochargers.
- Reduces pressure drop compared to the factory intake system.
- Supports increased airflow demands on tuned vehicles.
- Enhances throttle response and drivability.
- One of the most effective first upgrades for S58-powered M cars.
