See my below review with my Audi mechanic's recommendation. My MPG's have also increased after switching from a no-name oil separator to this new OEM one, car runs the best it ever has. Highly recommend this one.

My mechanic said other brands of oil separator dont have the right amount of vacuum/too much vacuum, which over time can pull at the seals. cause rear main seal failure and other issues. Go with OEM.

Exact OEM replacement at a lower price + FCP replacement warranty. You can't beat that.
