Enhance engine efficiency by capturing crankcase vapors and oil mist.
The Moroso Performance Air-Oil Separator is designed to effectively capture excess crankcase vapors and residual oil mist, preventing them from reentering the intake track. This innovative solution addresses the common issue of a vehicle's PCV system venting unwanted substances back into the intake manifold, which can compromise engine performance and durability. By plumbed inline with the PCV system, this separator significantly reduces detonation and deposits on the intake track, including the valves, thereby enhancing overall engine efficiency.
Constructed from high-quality polished billet aluminum, the separator features internal baffling and mesh media to optimize vapor capture. It includes a bottom drain with an elbow for easy and mess-free oil collection, ensuring maintenance is straightforward. The polished finish allows for customization, as it can be chromed, painted, or powder coated to match your vehicle's aesthetic. This air-oil separator is a crucial component for those looking to improve engine performance and maintain cleaner intake air.
