The BSH Competition Oil Catch can is definitely a great system! This kit is completely bolt on and is designed with one goal in mind - Keep your engine clean and healthy!
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.
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 more free flowing lines allow the engine to rev easily giving a more responsive feel to the engine as a whole.
Over the long haul these untended to vapors will build up over the intake valves leading to a host of running issues and an expensive repair bill to fix. With a catch can installed you will save yourself from dealing with this hassle.
All of the BSH Competition oil catch cans feature aluminum mesh baffling on the inside. This approach is used to obviously aid in the condensing of the oil vapors and also to allow the catch can to "breath". Ultimately the goal of the PCV system is to vent pressure from the engine so when designing our catch can lineup this was kept as the first priority with an efficient oil separation system being a VERY close second.
Here is an image of the baffling:
Sludge that you keep from entering your engine with the BSH Oil Catch Can:
All production fittings feature a military spec black hard anodized finish, all hose clamps, don't have such long legs on them once installed!!
The O-rings seen in the initial photos are part of a "twin seal" design. The billet fittings are machined to carry two O-rings each. They are designed to directly plug into the factory pcv connections without using some crazy plastic deals... This way you get a clean simple installation that maintains -10 sizing throughout. All the fittings but the one with the angle fitting are push lock so you don't need a bunch of hose clamps cluttering up an otherwise gorgeous engine bay.
Here are the pics, let me know if I can provide any further explanation.
