The Inlet Intake Manifold (OEM 11617811909) is a vital engine component that directs air from the throttle body into the engine’s intake runners and distributes it evenly to each cylinder. Designed for BMW diesel engines — particularly the N57/D30 3.0 L units — this intake manifold often incorporates swirl/flap control mechanisms to optimise airflow and combustion efficiency across various engine speeds. It’s a direct-fit replacement for worn, cracked or malfunctioning manifolds in a wide range of BMW 3, 4, 5, 6 and 7 Series, as well as SUVs like the X3, X4, X5 and X6 equipped with compatible diesel powerplants.

Frequently Asked Questions (FAQ)

Q1: What does an intake manifold do?
A: It routes air from the throttle body into the engine’s cylinders and balances airflow so each cylinder receives the correct volume — essential for efficient combustion.

Q2: Which BMW engines use part 11617811909?
A: This intake manifold fits BMW diesel engines in the N57 series (e.g., 3.0 L diesel) found in various 3, 4, 5, 6 and 7 Series cars and X3/X4/X5/X6 SUVs. Always check compatibility with your exact model and engine code before ordering.

Q3: What are signs the intake manifold needs replacing?
A: Look out for rough idle, loss of power, boost fluctuations or check engine light codes related to airflow problems or intake leaks.

Q4: Does this manifold include the flap control motors and gaskets?
A: Some aftermarket versions are supplied without control motors or gaskets. Always check the product description to confirm what’s included; replacement gaskets and actuator parts may need separate purchase.

Q5: Is installation difficult?
A: Fitting an intake manifold is a moderate-complexity task: it typically requires removal of adjacent components (like the throttle body and sensors). Professional installation is recommended to avoid air leaks or improper sealing.
