Performance Dual Air Intake System for BMW N54 Twin Turbo – 2” High-Flow Silicone Inlets

This dual high-flow intake kit is engineered to maximize the induction capacity of your N54’s twin-turbo engine. By replacing the restrictive factory air box with oversized 2” reinforced silicone inlets and high-volume cone filters, this system allows your turbochargers to draw in air with significantly less resistance. The result is a measurable improvement in throttle response and increased airflow efficiency, particularly at higher RPMs where the N54 engine reaches its peak potential.

The system is constructed with heat-resistant, reinforced silicone designed to maintain its structural integrity under high boost and elevated engine bay temperatures. This upgrade not only improves engine breathing but also dramatically enhances the auditory experience by amplifying turbocharger spooling and blow-off sounds.

Key Features

• High-Volume Induction: Replaces factory piping with 2” reinforced silicone inlets to maximize air delivery to the turbos.

• Reinforced Construction: Multi-layer silicone is designed to resist collapsing under high boost and withstand track-driven temperatures.

• Enhanced Response: Dramatically improves throttle sensitivity and top-end engine performance.

• Turbocharger Acoustics: Delivers a sharper, more pronounced turbo spool and audible blow-off sound.

• Precise Fitment: Developed to maintain a secure connection to factory turbo inlets with no cutting or drilling required.

• Dry Filtration: Includes high-flow dry cone filters that provide superior airflow without the need for oiling.

• Diverter Valve Integration: Includes block-off caps for a complete and secure system conversion.

Installation Tip

Unplug the car battery's NEGATIVE GROUND CABLE before installing this product. After the installation is complete, leave the cable disconnected for at least 60 seconds. This allows the vehicle's ECU to reset and properly calibrate for the increased airflow, which helps optimize performance gains and prevents potential check engine light errors. Always perform installation on a completely cool engine to ensure safety.
