Keep oil out of your intake manifold!
The BMS Genesis Zero Maintenance OCC keeps oil where it belongs preventing it from being sucked through the PCV system and coating your intake manifold, cylinder heat, and valves. In addition to the long term damage and maintenance headaches crankcase oil can cause over time it also reduces engine efficiency and lowers effective octane sapping performance. This unique easy to install solution combines the effectiveness of an OCC (oil catch can) with the convenience of an air/oil separator. Oil is separated from engine vapor within the OCC where it gravity drains right back in to the crankcase providing a truly install and forget it OCC solution. Never needs to be emptied or serviced! The system is CNC machined for precision performance and fully sealed to retain full factory emissions performance. Installation takes only minutes, is fully reversible, and includes all required hardware. Made in the USA.
Note the Genesis has two separate PCV paths, vacuum side and boost side. The BMS Genesis OCC is for the vacuum side which we’ve found contributes ~95% of the manifold PCV oil contamination. With the Stinger we have not found any significant benefit to adding a separator to the boost side (driver side) system and suggest leaving it factory.
