The Perrin Air Oil Separator is, as it's name implies, not a simple catch can. Unlike a catch can, these separators offer a unique approach to the same issue. The separator allows the oils collected to be drained back to the engine! This eliminates the need to constantly check the separator every few hundred miles and draining it like you would on a standard catch can. Simple maintenance is still required and will be detailed in the instructions on how to and how often it should be done.

The Perrin Air Oil Separator has different chambers within it to divert oil to the bottom of the can. From here, the oil passes through a reusable filter that removes any contaminant in the oils. A drain at the bottom then puts the oil back into the engine and oil free air into the intake. The bottom of the can is also heated using coolant to ensure the unit is the same temperature as the engine. This helps to decrease water condensation in the system and reduces the sludge found at the bottom of most catch cans.

The red or black powder coating provides a quality finish that you can show off under the hood while also ensuring it is protected from corrosion. The CNC machined fittings are anodized for corrosion resistance as well as provide a sleek and clean look. With minor need of attention and detail put into it's construction, makes the Air Oil Separator much more than just your average can.

Key Features:
  • Reduces oil contamination from the intake system.
  • Reduces carbon build up.
  • Works well on stock and modified vehicles.
  • Direct bolt on brackets make this a simple install on most models.
  • Requires very little attention or maintenance.
  • Will work with front mounted intercoolers on most applications.
  • 5 Year Warranty: Protects the original purchaser for up to 60 months from the date of purchase, the Perrin warranty is one of the best available.
Usage Notes: This system is designed to work with normal levels of blow by gasses. If you have an engine with excessive amounts of blow by gasses (built motor or higher mileage engine with loose ring gaps), you may still experience some oil passing through still.

I couldn't be happier with my purchase! I ordered around 9pm, and it was delivered to my door befit 11am the next day! I didn't pay for expedited shipping, but it was shipped faster than big shipping companies have a hard time doing! The price was even better than I could find on the internet at rival retailers. So, with the cost of the intake, shipping, and communication from the company, I'll be back back for more and I highly recommend this retailers! Thank you!

First time buyer from PIT. Working on a new project car. Customer service was solid! After placing my order they even contacted me to make sure the parts I ordered were compatible with my specific vehicle. We exchanged some info and verified the parts would fit my ride. Delivery was communicated, tracked, and arrived on time as expected. Got exactly what I thought I was gonna get: exact part and the replacement went smooth. Have PIT bookmarked now and will use them again soon! Prish PIT!!
