Subaru OEM Oil Cooler Connector Post (02-05 WRX, 04-21 STI, 05-09 LGT & OBXT)

This is the post which both holds on the oil cooler to the block, as well as has the receiver threads for your oil filter. It is sometimes necessary if you are either switching to the other style cooler, or simply need to replace the one you have.

This post is for Oil Cooler part #s 21311AA051 and 21311AA120

For the 2002-2005 Subaru WRX, 2004-2010 STi, 2005-2009 Legacy GT & Spec.B, and 2005-2009 Outback XT
