Product Details

The Genuine Porsche 99610702355 Air/Oil Separator (AOS) is a critical emissions control component designed for Porsche 911 (996) models. Located on the top right rear corner of the engine, this OE-quality separator ensures optimal crankcase ventilation and emission control.

Key Features:

  • Collects residual gases and vapors from the crankcase and funnels them back into the intake manifold for combustion
  • Functions as a small diaphragm distillery that separates oil mist in the crankcase, liquifies it, and returns it to the crankcase
  • Includes rubber boot (clamp sold separately)
  • Genuine OE Porsche part ensuring proper fit and function
  • Reduces overall engine emissions and maintains proper crankcase pressure

Why Replace: When the separator fails, you will see increased vacuum in the engine crankcase; in extreme cases, oil enters the intake manifold causing heavy smoke from the tailpipes. Regular replacement prevents costly engine damage and maintains optimal performance.

Alternate Part Numbers: 996 107 023 55, 996-107-023-55, 996.107.023.55, 99610702353, 99610702354, 99610723156

Best price by far! Fast shipping!

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

I was looking to buy a gale banks header for my jeep. I came across this site th eir price was nearly $100 cheaper than any one else. Fast shipping too. Thank you.

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

Great Company. I needed a part quickly and for the right price. They had the best price on the internet, and made sure it got to me in two days before I went away on my road trip. I spoke to a representative that was very helpful. I highly recommend Autoplicity! Thanks!!!

Great site! Just what I wanted!
