Application and Compatibility

The intake manifold is dedicated to BMW E87 and E90 models with N45 and N46 gasoline engines in the 116i, 118i, 316i, and 318i versions. The manifold's design is adapted to the cylinder head geometry of these units, allowing for installation in place of the factory part without modifications.

The component works with the fuel system of gasoline engines, ensuring appropriate airflow and maintaining factory operating characteristics. This makes it the right choice when replacing a worn or damaged manifold in BMW cars of this generation.

Construction and Technical Characteristics

The manifold is part of the components responsible for distributing air to individual cylinders. The shape of the intake runners has been designed for even cylinder filling, which is important for engine smoothness and volumetric efficiency.

The arrangement of ports, mounting points, and accessory connection points is in line with BMW's factory standard, facilitating installation and subsequent service. The manifold is designed to work with the factory engine control system, maintaining the original operating parameters of the power unit.

Condition, Origin, and Benefits of Installation

The offered BMW intake manifold is a used part from disassembly, allowing for economical repair of the intake system while maintaining the original manufacturer's specifications. Choosing parts from this group is particularly beneficial when aiming to preserve factory fitment and avoid compatibility issues with aftermarket replacements.

Replacing the intake manifold with a functional unit helps eliminate common symptoms of damage, such as intake leaks, unstable idle speed, or performance loss. A correctly chosen part helps restore proper engine operation and reduce the risk of additional faults resulting from an incorrect mixture composition.

Why Choose This BMW Intake Manifold

• Original BMW Design – maintains factory fitment for N45/N46 engines.
• Designed for gasoline units – compatible with fuel system operating characteristics.
• Direct replacement for the old manifold – no engine modifications required.
• Economical solution for intake system repair – especially for significant damage to the old part.
