Moroso Air Oil Separator 2008-2014 STI

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.
