This specially machined aluminium fitting replaces the stock PCV valve on top of the Toyota 4U-GSE and Subaru FA20 engine blocks, found in the 2015+ Subaru WRX, Subaru BRZ, Toyota 86, and Scion FR-S. It converts the threaded hole in the block to a 10AN male fitting, allowing a clean AN hose connection for catch can or PCV system plumbing.
