AMS Performance BMW G8X M2/M3/M4 S58 Air Intakes (Open Airbox) 2021+
AMS Performance Open Airbox Air Intakes replace the restrictive factory system on BMW G8X M2, M3, and M4 models with S58 engines. These intakes feature a massive open airbox and large-diameter piping for unrestricted airflow to the turbochargers. Dyno testing shows gains of 15 wheel horsepower and 12 ft-lbs of torque on 93 octane fuel across the powerband.
Key Features
- Massive Open Airbox: Houses dual oversized 4-inch inlet filters pulling in cool dense air from all directions for maximum volume
- 3.5-inch Aluminum Piping: Mandrel-bent for smooth laminar flow reducing turbulence and pressure drop before the turbos
- High-Flow Dry Filters: Reusable cone filters capture contaminants while flowing 50 percent more air than OEM
- Integrated Heat Shields: Block engine bay heat to maintain intake air temperatures for consistent power delivery
- Bolt-On Design: Direct fit using factory mounting points with no cutting or modifications required
Product Notes
- Filters require cleaning every 15,000-30,000 miles depending on driving conditions
- Pair with AMS intercooler and downpipes for full turbo efficiency
- Packaged in reinforced box to prevent shipping damage
Installation Notes
- Professional installation recommended.
- Complete install takes 45-60 minutes with basic hand tools
- Retains factory mass airflow sensor and crankcase ventilation connections
