Review on Mishimoto Black Expansion Tank for Subaru WRX/STI 2001-2007 - MMRT-WRX-01EBK by Jerome Pritchard

It is larger than the OEM tank. This causes friction in either the power steering line or the intake manifold line. If the dimensions were reduced in a few areas it would be ideal. I simply routed the old tubing around the power steering line to act as an insulator. 02 205Update: After 10 months part of the bracket failed at the weld - this caused a slow leak in the tank. The Mishimoto warranty lasted about a week and I had a new part. Had to pay $15 to send a replacement. So far happy with the part.
