This Lexus IS300 Mishimoto radiator is a great option, whether you're having overheating problems or need to replace your current radiator. Mishimoto's performance radiator is made from aluminum, which offers superior heat dissipation.

The radiator features a lightweight dual core made from 100% brazed aluminum with polished end tanks. The Lexus IS300 Mishimoto radiator also comes with a high-pressure radiator cap that can withstand up to 1.3 bar. This helps raise the boiling point of the engine coolant, providing a safer and more efficient system.

Note that this Lexus IS300 Mishimoto radiator only fits the manual-transmission IS300 due to the difference in transmission cooling lines.

Key Features:

• Full-aluminum construction with TIG-welded end tanks.
• Features two-row 1.42-inch thick aluminum core.
• Includes high-pressure radiator cap that effectively raises the boiling point of the engine coolant, providing a safer and more efficient cooling system.
