Elite Engineering Aluminum Clean-Side Oil Separator (CSS) Kit for C7 Corvette Z51 (Dry Sump) - High Performance Black Oil Catch Can - Improves Engine Efficiency & Reduces Carbon Buildup - Perfect for Track Days & Performance Driving

Clean Side Separator This direct fit replacement for your stock Oil Fill Cap completes any Catch Can installation by diverting clean, or fresh, incoming air through this unit. The Elite Engineering Clean-Side Oil Separator is specially designed to complement your oil catch can. Although approximately 90-95% of the oil ingestion via the intake air charge enters via the "Dirty" or "foul" side of the PCV system, the other 5-10% enter via back flow through the factory "clean" or "fresh" side intake tube. This occurs mainly when accelerating or at wide open throttle when intake manifold vacuum drops to zero and crankcase pressure is allowed to build. Our Clean-Side Oil Separator traps and removes these oil vapors before ingestion, while retaining 100% MAF metered air. The result is improved vehicle performance and fuel economy. Replacing your stock oil fill cap with our Separator retains an emissions compliant close system. This billet aluminum replacement is safe to use in all temperatures and contains a stainless steel coalescing media in the separation chamber to trap and retain most of the oil vapors for the periods of low or no intake manifold vacuum.
