2002 - 2007 Subaru WRX STI CSF Race Spec Radiator
CSF has been working with specialized Subaru race teams across America to prove that our B-tube technology works for the incredible Subaru boxer engine. The all new Subaru WRX STI CSF Race Spec Radiator utilizes innovative technologies make for the most efficient cooling radiator on the market today.
Combining the traditional oil cooler with the new CSF cooling system has culminated in the all new Subaru WRX STI CSF Race Spec Radiator. These race spec radiators keep your race car running cool, even at the limits. Subaru owners with over 500 HP using front mount intercoolers can run into overheating issues, which is a big reason why the new Subaru CSF radiator is the one of choice.
To prove this point the Subaru race team known as Snail Performance put the new Subaru WRX STI CSF Race Spec Radiator to the test. The results were enormous as the race team ditched their 3 row X-line Mishimoto radiator to the new upgraded race spec model. Here's just a small snippet from their website.
“Based out of Arizona, we see temperatures on track over 90 degrees early in the year and atmospheres do not cool down until late October. With temperatures this high, we have fought cooling issues all year with water temps quickly rising to 220 degrees plus in no time! It was clear the competitors extra wide triple row unit was not cutting it and was pulled for CSF part number 7028. This unit is a single row core which may lead you to believe the loss of capacity and surface area could never improve cooling issues. Fortunately for us, the team at CSF knows how to manufacture a quality and efficient core that easily beats the competition. “
With a fresh 550hp on tap, we took our SHOWKAR to both Inde Motorsports Ranch with NASA AZ and Willow Springs Raceway with Shift S3ctor Global Time Attack for recent testing. The results were phenomenal. With nothing more than a simple drop in of the CSF unit, we saw an immediate peak temperate drop of over 30 degrees! Despite our best efforts to heat the car up, coolant temperatures never rose passed 190. Keep in mind, this is all on the CSF single row street application drop in radiator without any ducting or additional cooling modifications all while an intercooler and oil cooler blocked direct airflow to 3/4 of the physical radiator core.
