Features & Product Details
RallySport Direct proudly carries a great selection of quality racing radiators brought to you by CSF.
Here, you are looking at the CSF Racing Radiator. This is a super-durable all aluminum radiator designed to replace your factory radiator to improve the overall cooling efficiency. Most factory radiators are manufactured using plastic upper and bottom tanks which will eventually weaken over time, and will leak which will cause you to overheat, which will open up an entirely different set of problems. CSF relieves this issue with all-aluminum construction to essentially become the end-all-be-all of radiators.

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.

Q: oil cooler and header compatibility Michav7177 months ago
The oil cooler portion of this does not work with my Tomei unequal length headers I purchased from you guys and on my 05 STI. It sits too close and there is no room for the lines. Have you guys Heard of this issue before?

A: When Rick installed this on an employees car, he did need to do some routing of the cooler lines to clear the headers.

Q: Better than a separate combo of radiators? Gerard11 months ago
i use my '11 STI as a second car so i track it sometimes per year and some mountain runs. My question is that this radiator with the oil cooler incorporate would get better coolant temps than a combo of a cooling radiator and an oil cooler (by separate)?

A: Fantastic question, and this is something that I think everyone should know, or at least be aware of. When it comes to oil temps, it's not always about getting the oil as cool as possible, it's about maintaining a stable oil temp. Now with a dedicated external cooler, you can keep your oil temps cooler for sure, and you usually have a thermostat to help regulate the temps, but to truly get the most out of an external cooler, you would want to delete your factory liquid to liquid oil cooler. Now with this CSF radiator, you get the advantage of having a massive heat reserve, and on the same side, a massive heat exchanger. The advantage of this is that you get ultra stable oil temps, and you can dial in the oil weight(and engine build if you really wanna get nerdy) to suit those temps. I would say for 99% of people, this is the best route to go. My ONLY complaint with it is the routing of the lines, as it's all near the manifold. And if you have the time, get the rad and the oil plate fitted up, and map out your line placement, and then order the correct fittings, adapters, lines, and heat sleeves. When I installed one on one of the employee cars I figured I would just use what we had on hand, and while I made it work, I wish I had planned on the extra time to map it all out and get additional fittings. I made it work just fine, but I don't really like "just make it work" lol. Hope this helps, and let us know if you have any questions, we would be stoked to help you out on your build! Thanks, Rick
