High-Flow Induction Upgrade for BMW N55 E-Chassis

Part Number: 51-76313

Give your turbocharged straight-six the airflow it deserves with the aFe Momentum GT Pro DRY S sealed intake kit. This premium induction upgrade replaces the restrictive factory airbox on N55-powered E-chassis models, delivering sharper throttle response, cooler charge temperatures and a noticeable lift in everyday drivability. We run this on our own N55 builds and our customers consistently praise the fit, finish and results.

Real-world performance benefits

• Measured gains up to +12 bhp and +14 lb ft
• Flows 16 percent more air than the stock airbox
• 400 CFM rating at 7 inches H₂O
• Sealed housing helps keep intake temperatures low for repeatable performance
• Oil-free Pro DRY S filter media for quick cleaning and zero mess

Engineered for smooth, stable airflow

One-piece airbox design: A CAD-optimised, roto-moulded cross-linked polyethylene enclosure shields the filter from engine bay heat. It includes a clear inspection window for fast filter checks and a removable auxiliary inlet plug so you can tailor airflow for your setup.

High-flow intake tube: The roto-moulded duct is tuned to reduce turbulence and maintain MAF sensor accuracy, offering OE-like fitment with significantly improved flow to the compressor.

Large dry performance element: A 9 inch inverted-top Pro DRY S filter with 3-layer synthetic media maximises surface area and can be washed and re-used many times. The rugged polyurethane construction ensures long service life.

Quality hardware and easy install: Stainless steel clamps and a silicone coupler provide a secure, durable seal. No cutting or drilling on factory components. Fully reversible.
