13718620473 Air Filter Housing | Intake System Structural Enclosure

The precision-engineered 13718620473 Air Filter Housing serves as the critical containment unit for the intake filtration system in 2018-2020 BMW 5 Series G30 and G38 models. This structural component securely houses both the air filtration element and acoustic silencer assembly, ensuring optimal protection against particulate contamination while maintaining proper intake airflow characteristics. Constructed using high-grade reinforced polymer materials, the housing features integrated mounting points that align precisely with chassis anchors, maintaining factory-specified positioning for all connected intake components. The precisely molded contours follow the engine compartment architecture to maximize space efficiency while protecting the filtration element from exposure to heat sources and road debris.

Strategic reinforcement ribs throughout the housing structure provide dimensional stability under varying temperature conditions and engine vibration frequencies. The integrated sealing surfaces maintain airtight connections with intake ducting components, preventing unfiltered air bypass that could compromise engine performance. The housing design incorporates precisely positioned service access points for simplified filter replacement procedures without requiring component disassembly. Engineered material composition ensures resistance to degradation from underhood heat exposure, automotive fluids, and environmental factors. The precisely calibrated internal volume maintains the designed acoustic resonance characteristics for optimal noise attenuation throughout the engine operating range. Installation maintains all factory sensor positioning and electrical connector access points without modification requirements, ensuring seamless integration with original engine management systems.
