My only complaint was that I had to buy an (3/8NPT x 3/8" barb) fitting to complete the install, it didn't come with it. Fits perfectly, and looks awesome! I did trim about 1/4" off the top hose to take the kink out. It's worth mentioning that i also have the Cobb overflow tank so I wouldn't have to deal with the stock one possibly not fitting, or removing the air pump cover. ... show more

Perfect fit, awesome cooling capability and looks great! I had to trim my coolant hoses to make this fit because it is a bit thicker than OEM, but my hoses were basically glued onto the old radiator, so you might want to get 2 new hoses as well. I bought mine for a great deal through Amazon Warehouse; product was listed as "used-very good", but it was new but slightly damaged packaging. The radiator wasn't damaged in any way. I included a pic of the box so you can see what "used-very good" looks like. ... show more

    • Great rad, comes with coolant tank mount as it doesn't fit with standard coolant tank location.
Fit great! Just FYI for any other buyers, this radiator will not fit with the standard plastic coolant tank in my 08 hatch wrx. However; it DOES come with a replacement plastic mount that mounts to the radiator, its at the bottom of the box. I almost threw the box out without seeing the replacement mount. My car runs much cooler and this radiator is vastly better than OEM! ... show more

So i bought this radiator for my 2011 subaru wrx, because i broke the plastic one that came with it. If i didnt need to install it i would have sent it back. However i need my car running so i insalled it. It works fine but it doesnt look good. Pros- it shipped fast, came two days early. Didnt leak, i water tested it. Cons- It was all dented up, but appears functional. ... show more

    • Great product, some items to know for 2009 STI fitment.
On my 2009 STI, this was not as direct a fitment as I was expecting. The secondary air intake pump cover wouldn't fit and had to be removed to make room for the radiator. Also, paired with the Mishimoto STI silicone hose kit (MMHOSE-STI-08BK), I had an unexpected fitment issue with one of the hoses not fitting completely correctly, and it had to be trimmed so it wouldn't hit my serpentine belt. ... show more

It arrived yesterday and was shipped in the stout factory box which will remain sealed for a month as it is a gift. It is a very pricey product when compared to other options...their silicone coolant hoses are pricey too...it is a name craze.

    • You can stand on it
This radiator has the nice feature of being able to be stepped on. Something which, as it turns out, the OEM radiator does not support. Hence why I bought this one! Actually though, it was somewhat problematically thicker than the OEM radiator in my 2008 Legacy GT. I had to cut all of the radiator hoses so they fit properly. The upper radiator hose actually still doesn't fit properly. I cut its length as perfectly as I could, but it still just barely touches the bolt on the power steering pump's pulley as well as the radiator fan on the passenger's side. We are talking about 1-2mm on each side, it's really that close. Each of those points where the radiator hose touches something that moves has been slightly worn away (again, barely a millimeter) to the point where nothing is hitting the upper radiator hose anymore, so everything is fine. The fit was ridiculously tight though. Pay careful attention to the upper radiator hose if you install this. ... show more

    • Works well. Doesn't look as nice as it should.
I try to stay away from Mishimoto products because I've always found them to be low quality. But the koyo rad I wanted was on back order so I settled for this, the welds do not look very nice and the aluminum finish has scuffs that don't look all that quality either, however it has lowered my coolant temps at WOT and under normal driving which is what I needed. Not a fan of this mishimoto cap, will be replacing it with a Cosworth. Fitment was perfect besides needing to trip the upper radiator hose about 1" ... show more
