BBK Performance have designed these oil separator kits specifically for late model EFI car or truck applications. An Oil Separator will keep oil out of your intake for a cleaner fuel burn and improved performance. This BBK Oil Separator Kit is CNC machined from solid billet aluminum. The oil collection tank features a knurled base for easy removal to drain the captured oil and an O-ring seal to prevent leaks. A high efficiency, multi-stage filter system is used to collect the very fine oil vapor droplets and deposit them into the easily removable bottom. This ensures only clean, oil-free air is able to pass through into the intakeInstallation Of this BBK Oil Separator Kit can be done with simple hand tools in less that 30 minutes.
