Amazon said fit for the wrx 2015. But when I received it doesn't fit it was not the same one as shown on the picture. Waste my time and Amazon don't want to respond just give me a 30 dollars on a gift card. Really upset.

    • Quality
These is a quality well constructed radiator. The fitment was perfect and everything went in without any snags. The top radiator hose had to be cut about an inch so it didn't hit the motor. The only cosmetic issue I had was inside the radiator cap had alot of welding lines.

Old and New side by side(see pics ). The Mishimoto radiator holds 1.75 additional Qts. of coolant to your system and brings your over operation temperature down several degrees. I live in Florida. i see the difference. A must for all Subaru applications.

A little disappointed with this one. Mishimoto is my go to for anything to do with cooling. Went with them on multiple builds. But this radiator, though I got it installed was slightly warped when I got it. Still works well and gets the job done. I ordered the fan but for the 08-14 models to install along with it, they said it would not work for my model year. It's a perfect fit but will be tight if you have an after market charge pipe. Initial test and bleed fans kicked In and there pretty quiet overall satisfied. 8 / 10 recommend ... show more

    • easy install
make sure you tighten the magnetic plug at the bottom before filling or it might leak. very easy to install on my 2016 wrx, filled coolant and no overheat issues and i didnt use anything to purge air.
