do88 Front Intercooler Radiator for Toyota GR Supra A90 (WC-400)

Challenges of the B58 Charge Air Cooling System

A common issue with tuned B58 engines is the rapid heat soaking of the charge air cooling system, particularly during track days. High intake air temperatures will make the ECU to reduce power output or put the car into limp mode. Even spirited street driving can prompt the ECU to pull timing and decrease power output due to high intake temperature.

• 80% larger core volume than the original radiator (OE).
• Dual-row core that is 48mm thick, increasing the cooling surface by 36%.
• Quad-pass layout, allowing water to pass through the radiator four times instead of two, maximizing core surface area utilization.
• Slightly higher 5mm ambient fin height (compared to the OE's 4.4mm), ensuring good airflow to the engine radiator despite the increased core thickness.
• Full aluminum construction, complete with durable TIG-welded end tanks.
• Increased fluid capacity (2,6 liter more) for optimal heat dissipation.
