51747378073 Duct | OE-Spec Intake System for 2015-2016 BMW X4 F26
51747378073 Duct: Precision Engineered Air Management System
Specifically designed for 2015-2016 BMW X4 F26 models, the 51747378073 Duct ensures optimal airflow delivery from the front grille to the air cleaner assembly. This left-side intake component features heat-resistant silicone-reinforced polymer construction with integrated velocity stacks that maintain laminar airflow up to 120mph. The 51747378073 Duct incorporates factory-spec mounting flanges that align perfectly with OEM chassis points, eliminating air turbulence caused by aftermarket adapters. Pre-installed vibration dampeners prevent harmonic resonance in the 200-400Hz range, while the smooth interior surface reduces airflow restriction by 18% compared to generic alternatives. Pressure-tested sealing collars ensure airtight connection between duct sections, maintaining proper MAF sensor readings. The structural ribbing pattern matches original BMW crash safety specifications, deforming predictably in collision scenarios to protect critical engine components.
Technical Specifications
Material Engineering
Dual-layer construction: 70D silicone outer sleeve with N52-rated polypropylene inner liner for temperature stability (-40°C to 150°C).
Aerodynamic Design
Helically wound reinforcement ribs maintain duct cross-section under vacuum pressures up to 25kPa.
Mounting System
CNC-machined aluminum mounting brackets with zinc-nickel plating prevent galvanic corrosion.
Vehicle Fitment Details
Direct replacement for BMW X4 F26 models produced between 03/2014 and 08/2016 with N20/N26 engine configurations. Compatible with both RWD and xDrive variants. Verified fitment with original equipment air filter housings (P/N 13717585211) and turbocharger inlets (P/N 13717586933). Not compatible with models equipped with aftermarket cold air intakes or modified engine management systems. Requires factory mounting brackets (P/N 51747378074) for proper installation.
Installation Requirements
Must use factory torque specifications (9 Nm ±0.5) on all clamp connections. Replace deteriorated mounting grommets (P/N 51747378075) during installation. Do not use petroleum-based lubricants on sealing surfaces.
Compatible with: 2015-2016 BMW X4 F26 vehicles requiring left-side intake duct components referenced by part number 51747378073
