CUSCO Oil catch tank Brand CUSCO (Japan) Website CUSCO.co.jp Part number 00B009HB An oil catch tank collects oil (vapours) coming out of the valve cover via the Positive Crankcase Ventilation (PCV) which are normally sent back into the air intake. The turbo, intercooler and other inlet parts get very dirty this way, making them less efficient. I've opted for CUSCO's 15 mm universal kit to use with 13 mm inner diameter (ID) SamcoSport silicone hoses. Nice and tight! The kit contains the catch tank, some garden hose, mounting hardware and a manual Related links Custom straight air intake How to clean the intercooler Modifications - Engine SamcoSport silicone hoses Top
