Product Details

10X Entries For Our 25th Anniversary Sweepstakes!

ECS Tuning now has the solution with our ECS Baffled Oil Catch Can System. Engineered in-house, our system is designed to collect toxic blow-by gasses, reduce carbon build up and reduce concentrations of acids, oxidants and water within the engine oil. 

Our mounting system is specifically designed to work with the F30 335i/xi. The black anodized aluminum bracket mounts perfectly to the shock tower while maintaining a largely natural look in the engine bay while the silicone hoses are pre-formed for a clean installation.

Due to the size of the OE engine cover some trimming will be required in order to run the OE cover with this catch can, our installation PDF outlines the modification required to retain the OE engine cover if desired. 

The N55 community has found a catch can to be very useful when it comes to oil separation. Our separator has proven results to not only catch oil from traveling back into the intake system, but also moisture. This allows for much cleaner valves as well as the oil being cycled through the engine, separating the moisture with the catch can avoids freezing in cold climates.

Key benefits of the ECS Baffled Oil Catch Can System:

  • Highly Efficient Oil Separator (Catch Can):
    • Strategically positioned 4 chamber baffle system maximizes oil / air separation 
    • 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
    • Knurled and black anodized integrated oil dipstick makes inspecting oil volume of the reservoir clean and simple
    • Fully serviceable for routine cleaning and maintenance; Includes 2.5mm allen key to remove baffle plates for cleaning
    • -10AN ORB (O-Ring Boss) fittings for leak-free fitting connections
    • 6061-T6 billet machined body, anodized black for lasting protection and appearance
    • Easy to drain reservoir, simply un-threads from the oil separator for quick draining or cleaning 
  • Precision-Designed Mounting System
    • Black anodized aluminum bracket offers a cohesive under-hood appearance
    • Installation utilizes factory mounting locations and secures the catch can snugly against the strut tower
  • Pre-Formed Silicone Hoses
    • Precise length hoses with molded bends - no trimming of hoses required
    • With hoses, longevity is key - 3-ply construction ensures excellent durability and flow

Engineered and manufactured in the USA, you can expect the best performance and longevity with our superior Oil Catch Can System from ECS Tuning!
