BMW uses a lot of plastic in their engine components to save weight and money. Unfortunately, plastic is damaged easily and the factory oil filter cap needs a special tool to remove. This cap is designed to use the original o-ring seal so no special parts are required. You only have to remove the original 'filter cage' from the original cap and transfer it to the new aluminum cap. The satin black anodize blends in with the rest of your engine bay making this a smart and subtle upgrade.
Here is a link to the original Genuine BMW oil filter cap if you are looking for that instead.

Modern emission regulations require a closed PCV/Breather system for cleaner operation. However, inefficient oil particle capture can lead to excessive oil vapor ingestion, causing carbon buildup, reduced performance, and fuel economy. ECS Tuning's updated ECS Baffled Oil Catch Can, now with an easy-to-empty 1/4" drain fitting, is engineered to collect toxic blow-by gases, minimize carbon deposits, and reduce oil contamination within engine oil. Recirculating oil vapor ensures emissions compliance without venting to the atmosphere.

There are a few reason having a catch can is an upgrade for a vehicle, from a separator system that no longer works to one that was never there. Modern day emissions regulations require the use of a closed crankcase ventilation (PCV) system to recirculate combustion blow-by gases from the crankcase back in to the intake to be burned. Unfortunately, these blow by gases contain water vapor (which is a byproduct of combustion) and pick up oil mist from and the windage cloud and cam lubrication system as they travel through the crank case. Due to less than 100% effective air/oil separation in the stock PCV system, some oil mist and water vapor gets carried back to the intake tract and over time cause oil deposits and carbon buildup in the intake manifold, intake ports, and on the back of intake valves. All will eventually lead to poor performance and reduced fuel economy, and the presence oil mist can in the intake charge even increase the risk of engine damaging detonation.
The catch can utilizes a strategically designed 4 chamber baffle plate system engineered to create multiple changes in the direction of airflow to cause oil droplets to fall out of suspension, maximizing the efficiency of the PCV air/oil separation. A dipstick is integrated into the cap so you can monitor the oil level, and the can is easily serviced. At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil. The ECS Tuning Oil Catch Can is CNC machined from billet 6061-T6 aluminum and with a stealthy black anodized finish for lasting durability and appearance, and includes everything needed for an OEM-like fully reversible installation.
The black anodized aluminum mounting bracket places the catch can in a location that looks like it should be there from the factory as well as pre-formed silicone hoses for a clean installation.

*Modification is required to maintain installation of the OE engine cover, this is outlined in the installation PDF.
* The baffle system is designed to direct the flow clock-wise or counter clock-wise depending on your setup (each can can be adjusted to flow in either direction).
