Radium Engineering Universal Air Oil Separator-Return (AOS-R)(VTA)

Universal & VTA
The vent-to-atmosphere air-oil separator has 2 side (inlet) ports. This is great for dual bank engines that have 2 crankcase vent ports. NOTE: For single crankcase vented engines, simply plug one of the inlet ports with Radium Engineering 14-0351. The VTA AOS-R features one giant non-restrictive outlet that is over 183% larger than the inner diameter of the 10AN inlets. This increase in volume slows air flow allowing contaminants to fall out of suspension. Additionally, contaminants are trapped with a diffuser permitting the oil sludge to fall back into the catch can preventing overspray in the engine bay. Furthermore, it is a dual stage design (located in the inlet and outlet). These free flowing chambers do not create any flow restriction.

NOTE: Because of the vented "air leak" in the system, the VTA AOS-R is not recommended for mass-air flow (MAF) sensor engines.
