The benefit of having a catch can on your vehicle 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 whats better to circulate to burn from what is more harmful to your engine.

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 universal drain system.

With direct injected engines this problem becomes more prevalent, and the N54 in your 135i or 335i is no exception. We're seeing a lot of N54 powered cars with drivability and performance issues due to significant carbon buildup in the intake ports and backs of intake valves. The “factory fix” is a walnut blasting service that commonly needs performed every 30,000 to 70,000 miles. Don't be part of this statistic! Our shop recommends an oil catch can be installed in-line in the PCV system to help reduce the build-up of performance robbing deposits and greatly reduce the need for costly walnut blasting service and related repairs in the future.

This kit includes the driver side mounting bracket designed specifically for the N54 engine bay with silicone hoses for a clean functioning install with no creative modification required.
