Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. These kits include everything needed for a complete installation. The catch can is plumbed in-line with a PCV valve and draws out oil and water condensation from the crankcase gasses that would otherwise be drawn into the intake manifold. Furthermore, the closed system prevents unwanted oil vapors from entering into the cabin.  FEATURES-Effectively raises the octane and increased engine performance from cleaner inlet air-Prevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc.-Excessive oil collection can be an indicator of a damaged engine.-Lowers hydrocarbon emissions-Capacity: 7 fluid ounces 20-0260-FL CATCH CAN KIT, PCV, GM LS1/LS6 ENGINE, FLUID LOCK The anodized aluminum catch can bracket mounts to the front RH side of the cylinder head. COMPATIBILITYGM LS1 Gen III Engine GM LS6 Gen III Engine Use 20-0785-FL instead for the following Gen IV engines: LS2, LS3 and LS7.
