Premium 51117295273 Grille for BMW 7 Series F02 LCI Front Bumper Ventilation System

Engineered specifically for BMW 7 Series F02 LCI models, this front bumper lower ventilation net with primary reference 51117295273 delivers optimal airflow management and radiator protection. The 51117295273 Grille features a textured black finish that maintains the vehicle's sophisticated aesthetic while providing durable performance. Designed with precise dimensional accuracy to match factory specifications, this ventilation solution integrates seamlessly into the bumper assembly without modification requirements. Its geometric pattern balances maximum airflow with effective debris filtration, protecting critical cooling components from road hazards. Manufactured using automotive-grade materials with UV-resistant properties, it preserves appearance and structural integrity through seasonal weather variations and extended service periods.

Model-Specific Compatibility

This ventilation grille is precision-engineered for 2013-2015 BMW 7 Series F02 LCI models including ActiveHybrid 7, 740i, 740Li, 740Li xDrive, 750i, 750Li, 750Li xDrive, 760i, 760Li, and Alpina B7 variants. It maintains direct compatibility with both standard and M Sport bumper configurations where original part number 51117295273 was installed. The component integrates with related systems including auxiliary radiators, brake cooling ducts, and front parking sensors without interference. For vehicles with custom bumper modifications or regional specifications, verification via 17-digit VIN is recommended to ensure proper fitment. Interchange numbers include BM1036157, 51117295274, 51117295275, and 51117295276. Installation requires no bumper removal when replacing existing grilles with damaged mounting tabs.

Engineering Specifications

Constructed from impact-modified polypropylene with 30% glass fiber reinforcement, this 51117295273 Grille maintains dimensional stability between -40°C and 140°C operating temperatures. The injection molding process creates consistent cell geometry with wall thicknesses optimized for vibration resistance and aerodynamic efficiency. Surface texture replicates OEM-style matte finishes using specialized tooling that creates light-diffusing micro-grain patterns. All mounting tabs feature stainless steel reinforcement cores that prevent breakage during installation while accommodating thermal expansion differentials. The open-area ratio of 68% provides unrestricted airflow to cooling modules while filtering debris larger than 8mm. Internal reinforcement ribs increase torsional rigidity by 45% compared to standard aftermarket alternatives, eliminating harmonic vibrations at highway speeds. UV-inhibited polymer formulation prevents color fading and maintains material flexibility throughout the product lifecycle.
