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 \u003cstrong\u003eN63B44O1\u003c\/strong\u003e engine bay degrades plastic sensor mounting lugs, causing unmetered vacuum leaks, erratic fuel trims, and false lean condition diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered 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.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 x 3\" Aluminum MAF Air Intake Tubes\u003c\/li\u003e\n  \u003cli\u003e4 x MAF Sensor Mounting Screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2014-2016 BMW 5 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN63TU (N63B44O1) \/ F10\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e445 hp \/ 480 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014-2016 BMW 550i Sedan (F10) 4.4L Twin-Turbo V8 (N63)\u003c\/li\u003e\n  \u003cli\u003e2014-2016 BMW 550i xDrive Sedan (F10) 4.4L Twin-Turbo V8 (N63)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the F10 5 Series?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2014-2016 BMW 5 Series equipped with the \u003cstrong\u003eN63\u003c\/strong\u003e 4.4L twin-turbo V8 engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre new mass air flow sensors included with these intake tubes?\u003c\/h4\u003e\n\u003cp\u003eNo, these housings require transferring your original factory OEM MAF sensors using the included mounting hardware.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned to satisfy stringent European powertrain tolerances, these aluminum housings preserve accurate sensor scaling while supporting the elevated intake volume demanded by the twin-turbocharged V8 platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67901479616760,"sku":"DS-E5SUL7Z85","price":119.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/bmw-maf-tube-pair-main_b7f2bdf6-e22e-4bd1-8c69-c50d848e05c1.jpg?v=1793337518","url":"https:\/\/performancechiptuning.com\/es\/products\/maf-air-intake-tube-pair-for-bmw-550i-2014-2016-4-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
