OE: 16126750475 Fuel Filter for BMW Gasoline Engines | BMW

Overview

The OE: 16126750475 fuel filter is designed for BMW gasoline vehicles that require stable and clean fuel delivery.
It supports port-injection and direct-injection gasoline systems by removing fine contaminants before fuel reaches the injectors.
This filter helps maintain smooth acceleration, consistent throttle response, and predictable engine behavior.
Its construction suits passenger cars and sport-oriented models used in daily driving and extended highway operation.

Compatibility

This fuel filter fits BMW gasoline platforms powered by the following engines:

• N52 naturally aspirated gasoline engine

• N53 gasoline direct-injection engine

• N54 twin-turbo gasoline engine

• Early N55 turbocharged gasoline variants

Common applications include BMW 3 Series, 5 Series, X1, Z4, and selected 6 Series gasoline models.
These engines rely on stable fuel pressure to maintain accurate injection timing.
The filter operates as the primary filtration stage within the low-pressure fuel circuit.
Its external dimensions and connector layout follow OE specifications for direct replacement.

Filtration / Material / Mechanical Design

The filter features a sealed cylindrical metal housing designed for durability and pressure stability.
Its exterior construction supports consistent performance during temperature changes and extended driving cycles.
OE-grade sealing surfaces ensure secure installation and stable fuel routing.
The housing design aligns with BMW standards for gasoline fuel systems of this generation.
This design supports reliable operation in urban traffic and long-distance highway conditions.

Flow Stability & Engine Protection

Stable fuel delivery supports accurate injector operation and smooth combustion.
The filter helps maintain steady idling and consistent throttle response.
Clean fuel flow reduces strain on the fuel pump during prolonged use.
By controlling fine contaminants, the filter supports long-term reliability of gasoline injection components.
