MAF Air Intake Tube Pair for BMW 750i 750Li (2013-2015) 4.4L

High-Flow Aluminum MAF Air Intake Tube Pair for 2013-2015 BMW 7 Series (F01/F02)

What it Does: The MAF Air Intake Tube Pair replaces the restrictive factory plastic mass air flow housings on the 2013-2015 7 Series to eliminate turbulent pre-turbo airflow and improve intake metering consistency.

The Stock BMW 7 Series Intake Housing Restriction

The twin-turbocharged N63TU V8 relies on twin independent mass air flow sensors to meter air to each cylinder bank. Factory OEM plastic MAF housings feature stepped internal walls, complex internal baffles, and molded seams that create boundary-layer turbulence right across the sensor element. Over repeated thermal cycles within the tightly packaged engine bay, the stock composite housings also suffer from micro-warping and brittle mounting tabs, causing unmetered air leaks and erratic fuel trim adaptations.

The Engineering Solution

Constructed from lightweight, precision-machined aluminum with a gloss black anodized finish, these 3-inch (76mm) outer-diameter housings deliver uniform cross-sectional flow directly past each hot-film sensor. Each tube features a dedicated CNC-machined MAF flange TIG-welded in position to guarantee a true airtight seal with the OEM sensor O-ring. Measuring an ultra-compact 4.7 inches (120mm) in overall length, this matched pair integrates cleanly into tight engine bay tolerances and pairs seamlessly with custom intake piping, silicone couplers, or high-flow cone filters.

Frequently Asked Questions & Fitment Warnings

Does this fit the F01/F02 7 Series?

Yes, this is a direct fit for the 2013-2015 BMW 7 Series equipped with the N63 4.4L twin-turbo V8 engine.

Are mass air flow sensors included in this kit?

No, this package includes the CNC-machined aluminum housings and mounting hardware; your factory OEM MAF sensors transfer directly into the welded flanges.

The BMW Precision Standard

Engineered to meet the tight tolerances of high-performance European twin-turbo systems, these CNC-flanged housings maintain critical MAF scaling geometry to prevent lean-condition check engine lights while providing structural heat resistance.
