Utilizing the engineering and design that brought about the first ever catch can system for the FSI, BSH was easily able to accommodate this design request.  For this new version of the recirculating catch can changes include an increase in the volume from 7 fluid ounces to 32 fluid ounces of actual capacity (from base to fittings). Also added are a JIC threaded dip stick for guaranteed leak free oil level inspection and a standard drain valve.
A natural byproduct of the crank case ventilation system is oil vapor making its way back into the intake. These gasses are recirculated back into the intake for emissions compliance. On factory cars where performance is only one piece of the puzzle this no problem. However when the best performance is the goal these vapors have to go! By allowing oil vapors to enter the combustion chamber you increase your chances for detonation significantly. Oil vapors will also gum up the intake valves over time. Direct injection engines are much more susceptible to this than port injection engines of the past as they do not have fuel passing over the valves to wash them clean.

BSH recirculating catch can systems catch oil vapors and still fully meet emission requirements. Internally the incoming vapor is forced to make a 120* turn through a high volume chamber baffled with aluminum mesh that forces oil vapors to condense and to separate from the air as it passes through. This oil then falls into the gut of the can and can be drained easily at your convenience.  

Outside of being a performance enhancing part, the Stage 2+ kit also completely remedies the very common PCV check valve failure on these engines. Symptoms of this failure are a noticeable loss in performance, a decrease in gas mileage, rough idle, and oil being blown out of the oil cap. This kit solves this once and for all!

Stage 2 + Kit Includes:
The full stage 2+ kit comes complete with every bit of hardware needed to install. This covers the catch can, bracket, CNC guidance block, manifold blockoff, PCV adapter, all aluminum fittings, lines, drain valve, dip stick and nuts and bolts.
