Review on Mishimoto Performance Aluminum X-Line Radiator for Subaru WRX/STI 2008-2014 by Anthony Payton

This radiator has a nice feature: it can be stepped on. The fact that, as it turned out, does not support the normal cooler. That's why I bought this one! In fact, it was a bit problematically thicker than the OEM cooler in my 2008 Legacy GT. I had to shorten all the radiator hoses to fit. The upper radiator hose actually still doesn't fit properly. I cut it to length as accurately as possible, but it still barely touches the bolt on the power steering pump pulley as well as the passenger side radiator fan. We're talking 1-2mm on each side, it really is that close. Each of those points where the radiator hose makes contact with something moving has worn slightly (barely a millimeter again) to the point where nothing else is touching the upper radiator hose, so that's fine. Although the landing was ridiculously tight. Pay special attention to the upper radiator hose when fitting one.
