The benefit of having a catch can on your F8x M3/M4 has to do with how much oil vapor is being recirculated back into the engines intake system to be burned. This recycling process is used mostly for emission purpose to keep these harmful vapors out of the atmosphere. Though it is better for the environment its typically not much better for you engine since the burnt oil will slowly become carbon build up & sludge through vacuum hoses, PCV system, and valves. The catch can assists in separating oil and water vapor from the crank vent system.
The Turner catch can features a 4 chamber, baffled design for the best efficiency when it comes to the separation process and 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. This catch can was also engineered for convenience featuring a dipstick to check the fill level and comes complete with a valved drain system.
This kit includes a passenger side mounting bracket design specifically for the S55 engine bay, and it features molded silicone hoses for a clean install without modification.
Due to limited space around the catch can mounting area in S55 applications, we strongly recommend the use of the optional drain system for easy evacuation of collected oil from below the vehicle.
