Description

BFI "Clean Catch" - Crankcase Oil Separator, B7 Audi A4 2.0TOne of the biggest areas of concern for the longevity of your FSI direct injection engine is the long term effects of oil vapor deposition in the intake and valve train. Even though all FSI engines come equipped with a cyclonic oil separator from the factory time has shown that these separators are not enough and that the biggest contributor to these vaporized oil deposits on the intake valves and plenum are the gasses emanating from the PCV system.


One of the biggest areas of concern for the longevity of your FSI direct injection engine is the long term effects of oil vapor deposition in the intake and valve train. Even though all FSI engines come equipped with a cyclonic oil separator from the factory – time has shown that these separators are not enough – and that the biggest contributor to these vaporized oil deposits on the intake valves and plenum are the gasses emanating from the PCV system. Without additional filtering and maintenance your intake valves could look like this:

 QUALITY

We have designed the best Oil Separator on the market for the FSI platform. Designed to help remove excess oil/water vapor from the intake tract and increase the longevity of your FSI engine. The Clean Catch Oil Separator will be the only catch can you will ever need to buy. Made from the highest quality components, these catch cans are built to last a lifetime, and beyond. Designed from the ground up – with the honing of many different iterations of internal baffle design, these cans both look and function as well, or better than any on the market today.  ENGINEERING

Each can employs a specifically designed V-shaped baffle to maximize surface area for increased deposition of condensed vapor, without sacrificing the flow characteristics necessary for the FSI PCV system to function correctly. Each design has undergone an extensive long term testing process - in both street and race applications to ensure that each can functions with maximum efficiency, without any loss in performance. Utilizing CNC aluminum components along with aerospace quality hose, connectors and hardware, these cans both function and look like an OEM quality piece.  SIMPLICITY

Installation of the FSI Clean Catch Oil Separator takes just minutes and is designed to allow clearance both for the stock engine cover/intake to be retained as well as the OE “noise pipe” to be used. Every FSI Clean Catch system comes with a matte powder coated aluminum can, high flow #8 braided and sport-crimped hoses and hose ends, along with in-house designed CNC machined PCV Port adapter and can bracket, as well as a billet intake manifold block off. All aluminum pieces are anodized black for longevity and good looks! Every Clean Catch system comes with our proprietary VAGPORT connection system, a revolutionary PCV connection system,consisting of custom designed and machined port adapters specific to Volkswagen and Audi applications.

Great fit, no slip
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
These looked too small for my feet, but now I love wearing them as they are comfortable and stay on my feet! They look great and the colors are easy to match. Excellent value for the money in my humble opinion.

I didn’t realize these were kids socks, until after I got them, but the fit is amazing and they stay put, without coming off my heels. I wear an 8.5-9 in women’s shoes.
