Features & Product Details

From the factory excess crankcase vapors, residual oil and moisture are vented back into the intake manifold and crankcase ventilation system. This can coat the pistons and everything else with a detonation prone layer of oil. This is no good in a turbocharged vehicle.

Moroso has come up with a 2 tank system that allows the factory crankcase ventilation to operate how it was designed. No other system on the market does this.

Billet Aluminum bodies compliment any engine compartment and can be polished, chromed or powder coated for a custom look. Each Separator has a billet aluminum clamp, a bottom drain with an elbow that makes draining the collected oil a mess-free operation. Includes stainless steel mounting brackets, 1/2" inlet and outlet fittings, 66" of 3/8" diameter and 66" of 1/2" diameter rubber hose for plumbing the Air-Oil Separators inline.

This is for cars with a TMIC and stock location turbo. This kit is not designed to be used with a FMIC or rotated mount turbo.

QUESTIONS & ANSWERS

  • Q: rotated mount turbo  sals7tmp304233 years ago

    What is it that causes this to not be able to be used with a rotated mount. If its a clearance issue, can this still function if the mounting location is changed even if it requires modifying the length of some of the hosing
    • 0 of 0 people found the following answer helpful

      A:  This part will sit right above the stock turbo and the lines will be ran to the top mount intercooler. We cannot confirm if this will work if you modify the setup.

  • Q: 05 WRX  RAWeiss91247174 years ago

    So ideally with the cruise control disconnected/removed this AOS should work on my 05 WRX? Theres no other specific fitment issues?
    • 0 of 0 people found the following answer helpful

      A:  If the cruise control is removed, then this should work on your 2005 WRX. Unfortunately Moroso has not been able to guarantee this, but that is what we have found.

      A:  We Have not tried fitment with the Cusco Tower Brace at this time. I have looked at a few photos online and have a strong feeling it will clear as long as the cans are dropped down.
