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. 

 

DETAILS:

  • CAD/CAM designed using Unigraphics Software
  • OE radial and deep drawn aluminum end tanks
  • B-Tube Technology - stronger, most efficient tube in the world
  • Wind tunnel tested for optimal radiator core cooling efficiency 
  • "Racing Style" aluminum drain plug
  • Brazed in CAB furnace
  • Military0grade special clad  aluminum used for tubes, fins, header
  • Plates and side brackets (JIS 3003 spec minimum)
  • Privately owned factories with full "in-house" tool rooms
  • CNC machined fittings
  • "Master Class" TIG welding
  • Individually leak tested
  • Vibration cycle tested
  • Thermal cycle tested
  • Wind tunnel tested for optimal radiator core cooling efficiency
  • Burst pressure and impulse cycle tested 10,000 times for strength
  • Salt spray tested for corrosion protection
  • 10-foot box "drop test" to ensure packaging protection
  • 30 point fitment inspection on critical dimensions to ensure OE fitment with no modifications necessary
  • Includes radiator cap

    NOTE:

  • Designed with built-in oil cooler

    CSF racing radiator w/ built in oil cooler is amazing 2 years ago
    5out of 5stars

    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.

    QUESTIONS & ANSWERS

    • Q: 4eat wrx  chap2 months ago

      Would I be able to use this on a 4EAT, and hookup the oil cooler as the transmission cooler?
    • Q: Perrin Radiator Shroud Fitment?  jilty2 months ago

      Will the Perrin Radiator Shroud fit with this radiator?
    • Q: oil cooler and header compatibility   Michav7173 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?
    • Q: Better than a separate combo of radiators?  Gerard7 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)?
      • 1 of 1 people found the following answer helpful

        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

    • Q: What size hoses and fittings are needed?  OilLineQuestions1 year ago

      Various responses note that you will need two additional oil lines for this item. The responses say you need two braided hoses that will stand up to the required temperature, pressure, and fluid (oil) that are two feet in length each with female AN fittings. But, what diameter should the hoses be? And what size fittings are needed? Please let me know. Thank you.
      • 1 of 1 people found the following answer helpful

        A:  You will need -10AN hoses and fittings for both the radiator and sandwich plate, and we would recommend mocking up the radiator to get final lengths for the hoses for best fitment.
