Features & Product Details
Improve the cooling efficiency of your vehicle with an all-aluminum CSF Racing Radiator. CSF radiators are designed, fabricated, and tested with rigorous practices that include thermal cycle testing, burst pressure testing, and they even went as far as wind tunnel testing to help improve area surface coverage during regular and high-performance driving conditions. The welding process consists of arduous welds to ensure that there are no leaks. And over time and mileage the plastic end tanks on the factory radiator will eventually crack under pressure and cause a leak potentially leaving you stranded with expensive repair bills. With an all aluminum design, typically this is the end-all be-all of all radiators. Save yourself the time and energy. Install a CSF Racing Radiator and don't look back.
Note that this radiator has the built-in oil cooler and it will come with a sandwich plate that comes with fittings.

I have had my csf radiator w oil cooler installed for a few months now and I finally tested it on a hot summer day. Yesterday was 100 degrees and a few good Highway pull raised my temps higher then normal. By that I mean I broke 190 degree coolant temps. The highest point was 193 after a 2-top4th gear pull. I literally just wanted to see what my temps would do. I was impressed. I have also autocross my car and the coolant temps stayed below 190 on 80 degree days. Greet product and I’m happy I went with it. Since it isn’t stated in the description of the product also know the fans actively cool the oil when stopped just like the coolant. So temps stay down in stop and go traffic.

A: You will keep your OEM oil cooler with this setup. You can delete this OEM cooler but you will need to bridge the lines so you are not leaking coolant.

A: You would need two of these guys. It should come with fittings that will hook right up to those lines. https://www.rallysportdirect.com/part/couplers-and-hoses/mmsbh-10-4-mishimoto-4ft-stainless-steel-braided-hose-w-10an-fittings
