Product Details

The Moroso 85481 PCV Air/Oil Separator is engineered to capture excess crankcase vapors, residual oil mist, and moisture before they can reenter your engine's intake tract. This professional-grade catch can system helps prevent detonation, reduces oil deposits on intake valves, and maintains intercooler efficiency in forced induction applications—resulting in cleaner intake air and improved engine performance.

Key Features:

  • Polished billet aluminum construction with internal baffling and cleanable mesh media for superior oil separation
  • Large body design with 2.88-inch diameter and 4.5-inch height provides excellent fluid capacity
  • Convenient bottom drain with elbow fitting for virtually mess-free oil removal
  • Complete kit includes heavy-duty brass inlet and outlet fittings, 36 inches of 3/8-inch PCV vapor hose, stainless steel mounting bracket, and billet aluminum mounting clamp
  • Polished finish can be chromed, painted, or powder coated to match your engine bay
  • Easy to clean and maintain for long-term performance

By preventing oil vapor from contaminating the intake system, this air/oil separator helps your engine breathe cleaner air, leading to better throttle response, reduced carbon buildup, and improved fuel efficiency. The durable aluminum construction and quality brass fittings ensure reliable performance in demanding automotive environments.

What I needed, and delivered on time.

Th Motorsport beat everyone’s price on my looks headers. Thanks a lot

Smooth and uneventful so far.

Great company. When I started looking into transporting the car I came across many sketchy companies. A lot of bad reviews, complaints about money being taken and not having the car picked up, etc. But Autoplicity had good reviews and I can see why! I paid my deposit of only $50, they picked up the car within 3 days and delivered it in 2 days. The truck driver had excellent customer service! Very happy with this company, I would recommend them and definitely use them again if need be.

Good quality product for a low price

just a little higher than your competition but you had stock

So far, so good. We will see how long it takes

easy

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
