Megan MR-RT-TS20-RL Left and Right Side Radiators Compatible/Replacement for 20+ GR Supra J29/DB 5th Gen

✅ Vehicle Fitment

Designed for:

• Toyota GR Supra (A90 / A91 – J29 / DB Chassis)

⚠ Confirm trim and cooling configuration before purchase.

Megan radiators for the 2020+ will specifically replace the left and right side radiators located underneath the fenders. Cooling is absolutely crucial during high performance driving. Maintained high load, high RPM instances dramatically increases heat produced by the engine requiring a lot more from the vehicle’s cooling system.

What Are Side Radiators?

The 5th-gen Supra uses auxiliary side-mounted radiators to:

• Support engine cooling

• Manage charge air and thermal loads

• Improve temperature stability under load

When you increase boost or track the car, these become critical.

Megan Radiators are comprised completely of aluminum. From the tanks to the primary core. Aluminum tanks are a great upgrade over the plastic usually found on factory radiators which are known to crack and leak especially as they age. The larger heat exchanging core is not only more efficient at transferring heat from the coolant, but also increases total coolant carrying capacity.

Megan MR-RT-TS20-RL GR Supra Radiators Performance Benefits

• Improved temperature stability

• Better heat management under boost

• Reduced heat soak during track sessions

• Supports tuned B58 builds

If you’re flashing it, downpiping it, or tracking it — cooling upgrades aren’t optional.

Installation Notes

• Professional installation recommended.

• Inspect hoses and coolant routing during install.

• Properly bleed cooling system after replacement.

• Use OEM-spec coolant.

Modern turbo platforms punish weak cooling systems fast.

Aluminum radiators mark a modern advancement in cooling. Not only does the material dissipate heat at close to double the rate compared to brass, but also reduced the overall weight of the vehicle and provides a stronger and more durable core and tube design
