When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system  baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain hole can be used with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

Features:

  • 6061-T6 billet machined body, anodized black for lasting protection and appearance
  • Strategically positioned 4 chamber baffle system maximizes oil / air separation 
  • Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
  • Sealed with a pre-installed viton O-Ring
  • Includes 2.5mm allen key to remove baffle plates for cleaning
  • Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
  • Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
  • Optional use drain hole (valve and hose sold separately, watch for our model specific drain kits!)

Upgrade Your BMW with ECS Baffled Oil Catch Can

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.

  • Key Features:
  • Highly Efficient Oil Separator: Strategically positioned 4 chamber baffle system maximizes oil/air separation and minimizes oil droplets in the intake tract.
  • Integrated Dipstick: Knurled and black anodized oil dipstick simplifies oil volume inspection.
  • Reservoir: Available in 6oz or 8oz capacity with a 1/4" NPT drain plug fitting.
  • Serviceable: Easily removable baffle plates and drain plug for cleaning.
  • Easy/Customizable Installation: Combine with the ECS Universal Bracket Kit for simplified installation and adjustable mounting locations.
  • Leak-Free Fittings: Machined -10AN ORB (O-Ring Boss) fittings available for secure connections (fittings sold separately).

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.

BMW's B58 engine has been great, but one major weakness is the PCV valve. As stated by BMW, "The PCV's rubber diaphragm seal may fail, causing insufficient engine oil separation. As a result, the engine may emit blue/white smoke from the exhaust tailpipes, shudder during operation, and/or run with reduced power (limp mode). At idle, a high-frequency whistling noise may be heard in the engine compartment, and the malfunction indicator lamp (MIL) may also illuminate." If your BMW is experiencing these issues, there is a very likely chance your PCV has failed. If so we recommend replacing your PCV with this Genuine BMW repair kit! Don't want to spend over $200 for this fix? We also offer T#23980285 which also replaces this valve but at roughly 1/10th the price!
