CSF is proud to present its latest innovation – a high-performance, all-aluminum radiator designed specifically for the Toyota GR Corolla and GR Yaris.
The GR Corolla has quickly risen to prominence in the hot hatch segment, especially among track enthusiasts. Its turbocharged 1.6-liter three-cylinder engine, borrowed from the GR Yaris, offers outstanding performance potential. Combined with all-wheel drive, a rigid chassis, and precision-tuned suspension, it is an excellent platform for competitive racing.
Following the success of the CSF x Jackson Racing 8285/ 8285B intercoolers, CSF received numerous requests for an upgraded radiator. As enthusiasts push their engines to higher limits, the strain on the cooling system increases. To meet these demands, CSF has developed a state-of-the-art high-performance radiator, ensuring optimal cooling efficiency and reliable engine performance in extreme conditions.
Why Upgrade to a CSF Radiator?
With years of expertise in manufacturing premium cooling solutions for Toyota vehicles, CSF has worked closely with customers, race teams, and engineers to develop a radiator that directly addresses the cooling challenges of the GR Corolla and GR Yaris.
At high loads, the factory radiator shows its limitations:
- Increased engine temperatures due to the intercooler positioned in front of it.
- Higher thermal stress from larger turbochargers and increased power output.
- Risk of overheating, causing reduced performance and protective shutdowns.
To counter these issues, CSF has developed a high-performance radiator with enhanced cooling capacity and efficiency.
CSF vs OEM
The stock Toyota radiator features a single-row aluminum core with plastic end tanks. While adequate for stock power levels, its 27mm thickness limits cooling performance.
The CSF radiator, in contrast, boasts a 42mm thick dual-row core, dramatically improving heat dissipation and cooling efficiency. Utilizing advanced B-Tube technology, it achieves 15% greater heat transfer efficiency compared to traditional oval tube designs.
