2015-2021 Subaru STI Oil Catch Can by Cusco

The blow-by gas which can be toxic is sent in to the mixture of fuel and air of a normal production engine can now be returned and sent to the combustion room along with the mixture with the use of this oil tank being separated from the toxic oil, and, where as in comparison to competition cars, the blow-by gas is let out into the atmosphere. This oil catch tank will not pollute the air or re-burn the unneeded toxic oil, but instead, catches it and recycles it into the tank.
