Verus Engineering Air Oil Separator (AOS) - Mazda Miata ND

Ensure the intake system remains oil-free with the Verus Engineering air-oil separator. Oil in the system reduces octane, which can lead to detonation, reduction in power, and carbon build-up on the intake valves.  We utilize four, 5 micron, coalescent filters, one on each inlet and outlet, baffling, and stainless mesh to ensure unprecedented air filtration of the crankcase air.

The units ship with an easy to use drain valve and are fully assembled and pressure tested before leaving.

Notes: The install requires the removal of the sound tube; if you have one.

Fitment: ND1 and ND2. 2023 models without a sound tube will require slightly different hose routing.

Anodized parts can potentially fade over time due to engine bay heat.

Science:

Our AOS has one job and that is to remove the oil from the engine crankcase system so the oil does not get into the intake system. Oil in the system reduces octane, which can lead to detonation, reduction in power, and carbon build-up.
