OVERVIEW

Keep your G16E-GTS engine running at optimal operating temperatures under track and aggressive street conditions with the CSF High-Performance All-Aluminum Radiator. Engineered as a direct drop-in replacement for both the Toyota GR Corolla and GR Yaris, this upgraded radiator features a massive 2-row 42mm core—significantly larger than the thin factory 27mm unit. Utilizing CSF's proprietary B-Tube technology and ultra-efficient 5mm multi-louvered fins, it increases heat dissipation surface area and coolant capacity to eliminate heat soak and maintain peak power output.

FEATURES

• Ultra-High-Performance Core: Features a 2-Row 42mm aluminum core for vastly increased fluid capacity and maximum heat transfer over the OEM radiator.
• Exclusive B-Tube Technology: Specially designed tubes increase internal surface area by ~15% compared to standard oval welded tubes for superior liquid heat transfer.
• Track-Spec 5mm Fins: Multi-louvered 5mm tall fins maximize airflow through the core while significantly increasing overall surface contact area.
• 100% All-Aluminum Construction: Fully TIG-welded aluminum end tanks replace brittle factory plastic tanks for long-term durability under high pressure.
• Auxiliary Sensor Port: Features a pre-plugged 1/8" NPT port on the right side tank for clean, accurate aftermarket coolant temperature sensor installation.
• Direct Drop-In Fitment: CNC-machined mounting brackets and OEM-style inlet/outlet connections allow simple installation with zero cutting or modifications.
