Item: CUSCO OIL CATCH TANK 0.6 liter FOR Silvia (200SX) S13/KS13 (CA18DE)220 009 A
The Cusco Oil Catch Can aids in trapping the harmful engine blowby gases which can hinder engine performance and rob horsepower. A typical modern day gasoline powered engines are equipped with a blowby recirculation passage that reenters the harmful gases back into the combustion chamber for emissions purposes. When routed inline with the crankcase PCV system, this oil catch can traps the harmful gasoline/oil mixture that made their way through the piston rings, and out the valve cover. This way, the oil/gasoline mixed substance is not reentered into the combustion chamber, resulting in a cleaner, more efficient burn.
