MAF Air Intake Tube Pair for BMW 550i (2014-2016) 4.4L

High-Flow Billet Aluminum MAF Air Intake Tube Pair for 2014-2016 BMW 5 Series (F10)

What it Does: The MAF Air Intake Tube Pair replaces restrictive factory intake housings on the 2014-2016 BMW 5 Series to deliver laminar, low-turbulence airflow across the dual mass air flow sensors for improved throttle response and stable metering.

The Stock BMW 5 Series Restrictive Factory Induction

The factory induction tract on the F10 550i uses molded plastic housings prone to thermal degradation and internal surface drag. Under elevated boost levels, the OEM corrugated plastic architecture creates localized turbulence across the hot-wire sensing elements, leading to erratic MAF voltage signaling. Additionally, continuous heat cycling in the "hot vee" layout of the N63B44O1 engine bay degrades plastic sensor mounting lugs, causing unmetered vacuum leaks, erratic fuel trims, and false lean condition diagnostic trouble codes.

The Engineering Solution

Engineered to eliminate induction turbulence, this upgrade consists of a matched pair of 3-inch (76mm) mandrel-profile aluminum tubes finished in corrosion-resistant gloss black anodizing. Each housing features a precision CNC-machined MAF sensor flange TIG welded directly to the body, ensuring an airtight factory O-ring seal without adapters. The constant 76mm internal bore and smooth internal walls eliminate boundary-layer separation, providing uniform cross-sectional air velocity across the OEM sensors to support aftermarket silicone piping and high-flow filtration systems.
