Bad news
Don’t even buy I have a 2.0 Wrx premium 2.0 and it does not fit 2015 radiator doesn’t line up with hoses or the bottom of radiator ! Do not buy

Good radiator, not a simple install if you have an aftermarket charge pipe
Good radiator. We have an aftermarket charge pipe by processwest. This does bolt right in, but the stock fan will not clear. You need to HEAVILY modify the passenger side stock fan to get it to clear, or order a slim fan.

Wrx radiator is solid
It’s a good radiator and keeps engine cool as it’s supposed to. Only complaint in the radiator mount bolts weren’t long enough to put on correctly had to use differnt longer bolts

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.

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.

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.
