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.

Great product!! Solid build! Only down side is install instructions. Not as clear as one would hope...
Very nice product, but missing parts

The box I received came only with the hardware shown in the pictures, which means that there is some missing parts: (1) 3/8 x 90 Barbed Fitting (1) Cap used to close the cross over tube (Step 7 in user manual) Despite the missing parts, which I didn't need because I'm using a custom setup, the product works great and is nicely finished.

Will these work with a Process West Verticooler TMIC in a 2013 WRX Sedan?
A: This is for cars with a TMIC and stock location turbo, it should work with that TMIC without any problem.

Q: Setup Alfred 2 years agoAnswer
Does this particular AOS system accommodate both valve covers and the pcv valve to filter out the oil vapors? Thanks.
Q: Difference PROcede 4 years agoAnswer
The difference in this unit and the other smaller body units are what exactly? Is it sized smaller for bigger intercoolers or is it sized different because one is better at filtering then the other? Is this system maintenance free like the Crawford unit?
A: As this uses 2 cans, there is no need to have as large of a single can that has to handle both crank case and heads. This system is not maintenance free will require draining.
