PWR 32mm Performance Radiator – Toyota GR Yaris

Hot track days and hard driving can push the GR Yaris cooling system to its limit. PWR's 32mm radiator is a direct replacement for the factory unit with 23% more core capacity, built to keep coolant temperatures steady when the standard radiator starts to struggle.

What makes it different

• 23% more core capacity than the OEM radiator
• Rolled dimple tube with a close-mesh fin for efficient cooling
• Hand TIG-welded aluminium throughout
• Factory-size outlets and a direct OEM fit, no cutting or modification
• Made in the UK by PWR
• Fits Toyota GR Yaris (2020 on) and GR Corolla (2023 on). Part number: PWR128416-002

Other radiator options

We also stock the CSF 2-row radiator and the AIRTEC radiator for the GR Yaris. The PWR is the one built for sustained track use. For a full cooling package, pair it with an oil cooler and the AIRTEC header tank.

Fitting at String Theory Garage

We bleed the system fully and check for leaks before the car leaves. We can fit this in our own workshop and check everything over before the car goes back to you. Get in touch when you order and we'll book a slot. See our workshop services for what else we do.

Questions we get asked

Is it really plug and play?
Yes. Take out the factory radiator and fit this in its place. Nothing needs cutting or trimming.
