51747210476 Hose | OE-Spec HVAC Component for 2011-2018 BMW X3/X4
51747210476 Hose: Precision Climate Ducting Solution
The 51747210476 Hose delivers optimized airflow management for 2011-2018 BMW X3 F25 and X4 F26 climate control systems. This front upper HVAC duct component precisely routes heated/defrost air through dashboard channels using OEM-grade polymer construction. The 51747210476 Hose features factory-spec curvature with integrated mounting tabs that maintain seal integrity across temperature fluctuations. Reinforced collar connections prevent air leakage at blower motor interfaces while flexible ribbed sections absorb engine vibration. Manufactured from thermally-stable composites resistant to coolant vapors and UV exposure, the duct maintains pliability from -30°C to +110°C operating ranges. Precision-molded contours match original equipment dimensions within ±0.8mm tolerance for leak-free airflow delivery.
Advanced Material Engineering
Polymer Composition
Three-layer construction combines flexible TPU core with abrasion-resistant outer coating. Hydrocarbon-resistant formulation prevents plasticizer migration.
Structural Reinforcement
Steel-wire helix embedded in critical bend areas prevents collapse. Overmolded flanges maintain connection integrity during thermal cycling.
Environmental Resistance
UV-stabilized surface resists dashboard heat degradation. Passes 1,000-hour salt spray testing for corrosion resistance.
Vehicle Fitment Specifications
Direct replacement for 2011-2017 BMW X3 F25 models across all trim levels including xDrive28i, xDrive35i, and sDrive28i configurations. Verified compatibility with 2015-2018 BMW X4 F26 variants regardless of climate control system type (automatic or manual). Maintains proper clearance with both standard and optional heated steering wheel components. Compatible with vehicles manufactured between June 2010 and March 2018 bearing VIN ranges WBAWL7C56BC633201-WBAZR8C37J6D98803 (X3 F25) and WBAXY4C56FD396701-WBA4Y9C50J6D92104 (X4 F26).
Requires original mounting points and factory HVAC assembly configuration. Not compatible with vehicles featuring aftermarket windshield replacements that alter dashboard dimensions. Professional installation recommended to ensure proper sealing at blower motor and vent distribution interfaces.
Installation Requirements
Requires partial dashboard disassembly for proper access. Essential tools include trim removal set and Torx T20/T25 drivers. Critical to verify duct orientation markers before final seating. Mandatory post-installation airflow testing recommended to confirm system integrity.
Compatible with: 2011-2017 BMW X3 F25; 2015-2018 BMW X4 F26 vehicles requiring front upper HVAC air duct components referenced by part number 51747210476
