Cooling is absolutely crucial during high-performance driving. Sustained high-load, high-RPM conditions dramatically increase the heat generated by the engine, demanding more from your vehicle’s cooling system. Megan Racing’s standard aluminum radiator for the 2000–2005 Lexus IS300 (Manual Transmission Only) is designed to provide improved cooling capacity over OEM units, making it ideal for street-driven and lightly modified vehicles.

All-Aluminum Construction: Constructed entirely from aluminum—including tanks and primary core—this radiator offers superior durability compared to plastic factory tanks, which are prone to cracking and leaking over time.

Improved Heat Exchanger Core: The larger, more efficient core increases total coolant volume and enhances heat transfer, helping to maintain optimal operating temperatures under demanding conditions.

Direct Bolt-On Fitment: Designed as a full bolt-on replacement that integrates with factory A/C condensers and fan assemblies. Due to its increased size, upgrading to slim-profile fans is recommended for clearance.

Reliable Performance: Whether you're running a basic bolt-on build or need dependable cooling for daily use and spirited driving, this radiator provides a solid upgrade over stock without added complexity.

For Greater Cooling Capacity: For more demanding applications such as track use or forced induction setups, consider upgrading to the Megan Racing Triple-Pass Radiator (MR-RT-LI01-V2) for enhanced performance.
