PART NUMBER: 11830-RSR46 (BCNR33, BNR34), 11830-RSR26 (BNR32)

Blow-by gas exiting the combustion chamber can mix with engine oil and come back up during the intake stroke. Under normal conditions oil collects in the intercooler, but blowback can cause parts related to intake, such as the airflow meter, to become clogged with oil. The NISMO oil separator separates the oil from the blowback gases returning from the cylinder head during the intake stroke, which limits the amount of oil deposited in the intercooler. Because it is designed to return the separated oil to the oil pan, the oil separator also reduces oil consumption. The blowback gases are returned to the engine and are not released to the atmosphere, making this a valuable device for automobile inspection procedures.
