This is a replacement piston for the four-pot/two-pot red Fuji Heavy Industries (FHI) brakes.
Sold individually; specify front or rear. (Yes, the rear piston is more expensive than the front one. We have no idea why.)
Fits all 2006-2007 Subaru WRX, and any other Subaru retrofitted with the red two-pot/four-pot brakes.
