Intake manifolds

Intake manifolds are key components of the intake system, responsible for uniform airflow to the engine cylinders. Their precise design and reliability directly impact the engine's performance, power, and efficiency. At Global Parts, you'll find a wide selection of used car parts. , including intake manifolds, ideal for BMW, Audi , Mercedes , Volkswagen , Mini and others . The intake manifold is typically made of aluminum or high-strength plastics, ensuring optimal airflow with minimal resistance. In BMW E60 series engines, such as the 520d with the N47 engine, the M52 and N47 intake manifolds are designed to handle airflow at pressures up to 2.5 bar in supercharged systems. Their design incorporates variable-diameter ports to optimize torque in both low and high rpm ranges.

What functions do intake manifolds perform?

Intake manifolds play a key role in the engine's operation: Even air distribution – Ensures equal air access to all cylinders, which increases combustion efficiency. Cooperation with the intake system – The intake manifold regulates air flow, cooperating with the throttle, intake valves and turbocharger. Increased engine performance – Thanks to appropriate design and airflow, intake manifolds improve engine power and efficiency. Modern intake manifolds can be equipped with variable geometry valves that adjust the air flow depending on the engine speed.

Types of intake manifolds and their parameters

Collector type	Compatible engines	Material	Additional functions
Intake manifold N47	BMW 520d E60/E90	Aluminum	Channels optimizing air flow, cooperation with the turbocharger
M52 intake manifold	BMW 320i, 520i	Aluminum	Fixed diameter ducts, standard airflow
E60 intake manifold	BMW 520d E60	Plastic	Lightweight design, reduced intake system weight

Why is it worth taking care of intake manifolds ?

Damaged or contaminated intake manifolds can lead to engine performance issues. Typical symptoms include: Loss of engine power – Dirty or damaged manifolds can restrict air flow. Uneven engine operation – Improper operation of the intake manifold can cause vibrations and uneven operation of the engine. Increased fuel consumption – A faulty intake manifold results in suboptimal combustion of the fuel-air mixture. At Global Parts, we offer original used intake manifolds that have undergone extensive quality testing, ensuring their durability and reliability. Additionally, intake manifolds can be classified by their channel design: parallel (fixed geometry) and variable (flow control). Variable manifolds increase low-rpm efficiency by up to 15% compared to standard manifolds. In practice, the BMW E60 520d intake manifold allows for an optimal air-fuel mixture in the 1,500–4,500 rpm range, which improves ride smoothness and acceleration.

How to choose the right intake manifolds ?

When selecting intake manifolds, you should pay attention to several key aspects: Vehicle-specific fit – Every engine has its own specific design requirements. At Global Parts, you'll find intake manifolds perfectly suited to BMW, Audi , Mercedes , Volkswagen , Mini , and more . Technical condition – Used intake manifolds should be free from cracks, leaks and other damage. Manifold Type – Depending on your vehicle’s equipment, you may need a variable geometry or standard manifold.

Step by step – how to choose an intake manifold

1. Check the engine model and year of manufacture – e.g. N47 (BMW E60 520d) or M52 (BMW 320i/520i).
2. Specify the type of collector – standard or variable geometry.
3. Pay attention to the material and construction – aluminum, plastic, channels optimized for flow.
4. Compare the airflow parameters – larger channels increase power at higher RPMs, smaller ones improve torque at low RPMs.
5. Choose the right model from our offer, compatible with your engine and intake system .

Why choose used intake manifolds ?

Used car parts , such as intake manifolds, are a practical solution that allows you to save money while maintaining high quality. By choosing used intake manifolds, you gain: Lower costs – Used intake manifolds are much cheaper than new ones, but offer equally high quality. Ecology – Recycling car parts supports environmental protection and reduces waste. A wide range – In our store you will find intake manifolds for the most popular car brands. Used intake manifolds are compatible with various vehicle models, making them easy to install as part of an engine upgrade. For example, the N47 intake manifold can be installed on several BMW 520d E60 and E90 models, maintaining full intake system performance. This can save the user up to 40-60% compared to a new manifold.

How to take care of intake manifolds ?

To ensure that intake manifolds function reliably for a long time, it is worth following a few rules: Clean intake manifolds regularly to prevent carbon build-up that can restrict airflow. Check the condition of the manifold gaskets to prevent leaks and loss of engine power. Monitor the operation of variable geometry valves – their incorrect operation may reduce the efficiency of the drive unit. If you need a replacement, you'll find the right used car parts at Global Parts that will restore full functionality to your intake system.

Practical tips and additional information about intake manifolds

• The N47 and M52 intake manifold assembly is compatible with the original intake system, ensuring full compatibility with the throttle body and turbocharger.
• E60 manifolds have an average weight of 2.5-3 kg, which reduces the load on the engine and makes installation easier.
• For models with variable valve geometry, airflow is electronically regulated between 1,000 and 6,000 rpm, optimising both power and fuel consumption.
