Intended for use with recirculated AOS kits, or catch cans being vented to the atmosphere, this specially machined aluminum fitting replaces and deletes the stock PCV valve on top of the Subaru FA20, FA20F, FA24D, FA24F, and Toyota 4U-GSE engine blocks. 

This black anodized 6061 aluminum fitting converts the threaded hole in the block to a straight thru 10AN male fitting. The fitting has an overall height of 3.1 inches.

• 15-21 WRX (FA20F)
• 2022+ WRX (FA24F)
• 14-18 Forester XT (FA20F)

NOTE: This fitting is universally compatible with 3/8"-19 BSPT threads.

• Always apply a PTFE thread sealant to the BSPT threads before installing the fitting into the block.
• Hand tighten the fitting into the block first, then use a 7/8" deep socket wrench to spin the fitting another 1.5 to 3 turns.
• This fitting deletes the PCV valve. If connecting this to a catch can that breathes back into the intake manifold, a PCV valve must be installed somewhere in the system to meter the airflow into the intake manifold and prevent any reverse airflow into the crankcase.
• A PCV valve must be used. A check valve can not be used in place of a PCV valve.

This kit includes one anodized aluminum PCV delete/replacement fitting.
