BBK Oil Separators are an excellent solution for modern fuel injected engines that often suffer from poor fuel burns, caused by their design, which sends oil vapor from the crankcase back thru the PCV system to the air intake. BBK Oil Separator Kits are specially designed to keep oil out of your intake system. This guarantees cleaner fuel burn and superior performance. The installation process is quick and easy Ã» it should take 15 minutes or less, because the oil separators are compatible with OEM style connectors and hoses. But, please, keep in mind that BBK Oil Separators are NOT currently CARB approved.
