Purpose and compatibility

The presented camshaft is dedicated to popular BMW E87 and E90 models in 116i, 118i, 316i, and 318i versions with N45/N46 engines. Using an original component from the same engine family ensures proper cooperation with the cylinder head, tappets, and timing control system, without the need for structural modifications.

By maintaining the factory camshaft parameters, it is possible to restore correct timing phases, stable idle operation, and proper engine response to load, which directly impacts the refinement and performance of the power unit.

Technical characteristics and role in the engine

The camshaft in N45/N46 engines is responsible for precise control of the opening and closing of intake and exhaust valves. The appropriate cam profile, their arrangement, and cooperation with other timing components influence:

• proper filling of cylinders with the air-fuel mixture,
• efficient exhaust gas evacuation from the cylinders,
• stable engine operation across the entire rev range,
• maintenance of factory power and torque parameters.

Using an original camshaft from the same engine family helps avoid issues with incorrect valve clearance, excessive timing noise, or performance drops resulting from an unsuitable cam profile.

Condition, origin, and benefits of using a used part

The item comes from a dismantled BMW vehicle, which means it is a part of factory origin, designed specifically for use with N45/N46 units. Choosing this solution allows for:

• preserving the original build quality characteristic of BMW,
• reducing repair costs compared to purchasing a new component,
• maintaining full compatibility with existing engine accessories.

When properly installed by an experienced mechanic, this type of camshaft provides a solid foundation for restoring the correct operation of the timing system, without the need for interfering with the cylinder head construction or changing engine control settings.

Why choose original BMW Camshafts

Original BMW Camshafts are designed for specific power units, which translates into precise fitment to the cylinder head, appropriate surface hardness, and durability under high-load conditions. Unlike aftermarket replacements with a universal profile, the factory camshaft ensures:

• consistency with engine control unit maps,
• proper cooperation with the fuel and ignition systems,
• lower risk of accelerated wear of mating components.

This solution is particularly recommended for repairs of N45/N46 units, where the precision of valve control is crucial for the durability and refinement of the engine.

Repair expansion and related components

If you are planning a comprehensive repair or upgrade of the engine area in your BMW and need other elements from the same group, such as additional camshafts, control elements, or related timing components, check the available parts in the BMW Camshafts category.

When planning timing work, it is also worth checking out practical tips regarding diagnostics and replacement of components in BMW units – you will find helpful information in the article "BMW N47 timing chain – typical failure and repair using original BMW parts", which discusses, among other things, symptoms of wear and the advantages of using used parts of this brand.

If you want to reduce the vehicle's downtime in the workshop and better plan a larger scope of engine work, it is also worth reading the material on the impact of a wide range of used parts from one warehouse on vehicle repair time, which facilitates logistics and reduces downtime.
