CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology.

Integrated Oil Cooler

It's been a productive 2015 year for CSF's Racing & High Performance division, and one of our most innovative product lines so far has been our innovative "O"� Series line of race-spec all-aluminum radiators with built-in oil coolers!

The CSF "O" Series Radiator for Subaru WRX and STI was developed alongside industry leading Subaru engine builders & race tuners, LIC Motorsports from Northern California. CSF also reached out to one of our closest race teams, Subaru tuners, and dealers; Snail Performance, to help with fitment and performance testing in the hot Arizona desert they are regionally located in.

B-TUBE TECHNOLOGY

Unlike a regular oval shape "O"� type radiator tube, CSF uses a specially engineered tube in a shape of a "B."� These "B-tubes"� are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O"� shape tubes that are welded.

The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes "“ producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes"� you are able to get "dual liquid laminar flow."�

High Efficiency multi-louvered fins

CSF uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.

DESIGN & ENGINEERING

CSF aims to lead the cooling system industry by introducing new technologies and manufacturing processes that allows us to be on the cutting edge of heat transfer innovation.

ADVANCED ENDTANK DESIGNS

CSF offers three all-aluminum end-tank designs to match any style and performance need.

FINISH

Each CSF high-quality radiator is completed with an industry-leading 1 hour, hand-polished "Show-Stopperâ„ ¢"� Mirror Finish. Our hand polishing tools and techniques in our new polishing center located at the end of the production line ensure that every CSF cooling system looks just as good as it performs

 

Features:

  • These radiators utilize a 2-row 42mm core that features CSF's exclusive B-tube technology, as well as an ultra-efficient 6.5mm multi-louvered fin for maximum surface area contact, heat dissipation, and extreme performance capabilities.
  • Equipped with an all-aluminum racing style drain plug for quick and reliable fluid changes
  • Includes CSF 1.4 Bar (20 psi) radiator cap
  • Engineered and designed to be a complete "drop-in fit"� install. Works with all the OEM brackets, fittings, AC condenser, hoses, and fan shrouds (only minor trimming needed at fitting locations)
  • Featuring a robust 4-plate liquid-to-oil plate-type oil cooler built into the bottom end tank. A liquid-to-oil cooler is much more efficient than a conventional air-oil cooler. Lab-tested in CSF"�s ISO certified in-house lab testing facility to reject heat better and at a faster rate than a 10-row air-to-oil cooler. In addition, by being placed in the bottom end tank, the oil temperature is regulated by the thermostat of the cooling system. Never have to worry about operating temperatures not warming up fast enough in cold weather climates.
  • Complete with 2 AN-10 male fittings and is compatible with many popular aftermarket engines and exhaust manifolds.
  • This kit comes complete with a sandwich plate and forged right angle -10 fittings made by BAT (CSF was forced to switch to another top-tier company for the included sandwich plate due to the previous manufacturer's supply chain issues)
  • Topped off with the industry's finest 1-hour hand polish "mirror finish"� for a look that matches the performance.
  • Installation of this unit will require an additional 1/4 to 1/2 litre of oil

 

Vehicle Fitment:

Note: Some minor modifications needed to fan shroud to clear oil lines. Upper radiator hose may need trimming. Overflow hose will require replacing with longer hose.
