CSF High-Performance Radiator for GR Corolla & GR Yaris

Why upgrade?
The GR Corolla’s 1.6L turbo engine is powerful and popular, especially on the track. When drivers increase power and push their cars hard, the factory radiator struggles to keep the engine cool. CSF designed this radiator to prevent overheating and keep performance strong.

Key Features:

• Big, efficient 2-row aluminum core (42mm thick) for better cooling vs. factory’s 1-row (27mm thick)

• Special B-Tube design boosts heat transfer by 15%

• New tall fins (5mm) with a multi-louvered design to maximize airflow and cooling

• CNC-machined mounting brackets with OEM-style inlet/outlet — easy “drop-in” installation, no modifications needed

• Aluminum tanks instead of plastic for better durability and heat resistance

• Pre-plugged temperature sensor port for easy coolant temp monitoring

• Foam strips for better sealing and airflow

• Designed with extra space for large aftermarket intercoolers like the CSF x Jackson Racing model

• Fully TIG-welded aluminum construction for strength and long life

• Fits both GR Corolla and GR Yaris with one part number for convenience

• Covered by a 2-year limited warranty

Why is this better than stock?

• Factory radiator is plastic tank, single-row core, limiting heat dissipation

• CSF radiator is all aluminum, double-row core, and designed for much better cooling, especially with bigger turbos and hotter track conditions

• Improved durability means it can handle tough driving without failing

• Extra space for larger intercooler pipes avoids clearance problems common with other aftermarket radiators

OEM Part Numbers:

• Toyota GR Corolla: 16400-18060

• Toyota GR Yaris: 16400-18050

This radiator keeps your GR Corolla or GR Yaris cool under heavy use, helping avoid engine limp mode and maintaining peak performance during track days or spirited driving.
