BFI "Clean Catch V2" - Crankcase Oil Separator (Audi B8 4.2)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.

Yes, it was tough to change to whipless but it also meant I could benefit from the lighting without huge whips behind me. It’s a personal choice but these worked out great. Highly visible and bright and the install was pretty straightforward and simple. You get everything you need with the kit. They look good and seem to be holding up durability wise very well. Overall, I may not stay with them over time but it won’t be because of quality or function. It’ll be because I want to see the long whips again behind me.

Perfect fit for a Tacoma.

There are 2 headlight bulb retaining clips in this packet that fit my 2013 Tacoma. Fits perfect, no modifications needed to the clips. Toyota dealers do not sell these clips alone, they must be ordered with the headlight housing. eBay has one for $50!!! AMZN beats them all.
