Billet PCV Adaptor Pipe WRX 1992 - 1996The Fuji Racing Adaptors replace the cheap mass produced plastic ones that are used from the factory which go brittle over time and can crack causing Crank Case vapors & residue to leak out and cover the top of the block. Replacing your factory plastic adaptor eliminates this from ever happening again. Each Adaptor is machined from a single piece of billet alloy, hard anodised in the iconic Fuji Gold, and laser etched with the Fuji Racing Logo
