CSF Performance Radiator Subaru WRX/STI 2008-2021 | 7094

The main reason I was replacing my OEM radiator was to head off any issues with the plastic caps going into this summer after upgrading headers, up pipe, and turbo. With the expectation of additional radiant heat under the hood I wanted to be sure the block was receiving the cooling it requires and CSF delivered! Even on the hottest day after it was installed (102°) my coolant temps barely touch 190°.

Love this radiator, keeps the car cooler while pushing it hard, can’t wait to see what it can handle

I’m very happy with my purchase! Called out to IIR and they had great customer service and were very informative! The packaging was awesome not a scratch or ding on it and is waaaay better than my stock. Very much needed and they even gave me a discount! Thank you IIR 🙏

great rad

Perfect quality and easy to install.

Did not have any labels on the box regarding which car you bought it for. Overall shipment was quick, and no damage to the box.

Radiator has great quality easy install. Got it the next day I order it they are quick.

Fit perfectly on my 2018 wrx, paired with mishimoto hoses. Stock fans fit, very close fitment to the top mount intercooler charge pipe though but it did fit. Very high quality radiator and it's significantly thicker than stock

Very well made car runs incredibly cool

IIR just ab got it to me next day which was amazing but the product itself is good quality. Thicker than OEM too. Haven’t brought the car out to really test it and see how much of a difference but so far so good.
