Need a Genuine Subaru set of Water Crossover Pipe Orings for your 1993-2019 Subaru . Your kit will include oem sealed items. The kit will include Water Transfer Pipe O-ring 806933010 x2 (please note these come in bulk bags of 5 from subaru so you may get o'rings in a bag without the part number but these are genuine!!!!) Don't settle for aftermarket components of questionable quality and always insist on Genuine Subaru replacements. Fits: 2003-2006 Subaru Baja 2013-2019 Subaru BRZ 2013-2019 Subaru Crosstrek 1998-2019 Subaru Forester 1993-2019 Subaru Impreza 2002-2019 Subaru WRX 2004-2019 Subaru WRX STI 1990-2019 Subaru Legacy 2000-2019 Subaru Outback The water transfer pipe is the aluminum coolant pipe that crosses over the cylinder block underneath the inlet manifold. It's not uncommon for it to leak onto the top of the engine block. TWO of these O-Rings are required for an easy and inexpensive fix!
