Details : 

BSH Speedshop is proud to bring you it’s all new recirculating Competition Catch Can system for the BMW N54 engine. The BSH Competition Catch Can kit is a completely bolt on and emissions compliant hardware package. This performance and longevity enhancing system connects together using in house manufactured billet adapters that simply clip into the existing connections found on the N54 engine. Blowby gasses pass through these adapters into -10 oil and heat resistant lines and through the N54 specific BSH Competition Catch Can which has an important layer of aluminum mesh baffling to aid in the separation of oil and air. BSH simplified installation by designing a laser cut bracket and a new N54 specific catch can to fit perfectly giving a stock appearance. Installation and removal for draining is made simple by utilizing a drain plug mounted at the bottom of the can, and 2 easy to remove 4mm allen screws, allowing the can to come off and on in minutes. To check fluid level, BSH has added a billet dip stick for function without taking away from the form of the product by using an unsightly plastic viewing tube. This part is a direct addition to the factory PCV system and installs without any permanent or unsightly modifications to the vehicle. 

Function: 
The purpose of a catch can system is to collect/vent the blowby vapors inherent as part of the combustion process. The factory setup sucks these oily vapors directly back into the engine exposing them to everything in their path. Removal of these vapors is especially important on direct injection engines. Port injection engines have detergent enhanced fuel passing over the intake ports constantly cleaning off the intake valves. Direct Injection does not allow for this as the injectors spray right into the combustion chamber. Over time these oils harden and cake to the intake valves causing drastically reduced head flow, cold start misfires, greatly increased knock retard and of course a nice expensive bill to clean it all out. In the short term getting these vapors out of the combustion path reduces knock retard by not allowing oil vapor to mix with the air fuel mixture. In addition the free flowing lines allow the engine to rev easily giving a more responsive feel to the engine as a whole.
