Subaru Breather Fitting Tee Piece Block Black

the Aeroflow performance breather adapters replace the cheap mass-produced plastic ones that are used from the subaru factory. With heat over time these will go brittle and can crack causing crank case vapors & residue to leak out and cover the top of the block. These adapters are made from billet aluminium which eliminates this from ever happening again. Available in either the 90 degree block or the tee piece which both work in the oem breather setup or when using a custom catch can setup.
