Specifications
Part Details:
The Mishimoto Performance Aluminum Radiator is designed to improve cooling efficiency for the Subaru WRX by increasing coolant capacity and heat dissipation compared to the factory radiator. This upgrade helps maintain more consistent engine temperatures under higher thermal loads, including spirited driving and warmer operating conditions.
Constructed from durable aluminum and engineered with a high-efficiency cooling core, this radiator provides improved heat transfer while retaining a direct OEM-style fit. It installs using factory mounting points and is compatible with stock fans and shrouds, making it a straightforward replacement for the original radiator.
Performance & Cooling Efficiency
Compared to the factory radiator, the Mishimoto aluminum radiator offers increased surface area and improved airflow through the core. This allows heat to be removed from the coolant more effectively, helping reduce temperature spikes during extended driving or increased engine load.
Improved cooling consistency supports overall engine reliability and makes this radiator a practical upgrade for both daily-driven vehicles and lightly modified performance builds.
Design & Fitment
Designed as a direct-fit replacement, this radiator matches factory dimensions and mounting locations for proper alignment and secure installation. The aluminum construction also improves durability compared to aging factory components, making it a solid option when refreshing the cooling system.

Frequently Asked Questions (FAQ)
Will this radiator fit my WRX without any modification?
Yes. This radiator is a direct-fit replacement that matches factory dimensions and mounting points, and is compatible with stock fans and shrouds. No cutting or modification is required.
Do I need to upgrade anything else when installing this radiator?
No additional components are required for installation, though many owners pair a radiator upgrade with new coolant hoses or a fan and shroud upgrade as part of a broader cooling system refresh, especially on higher mileage vehicles.
What is included with this radiator?
This radiator includes a Mishimoto 1.3 Bar High-Pressure Radiator Cap and is backed by the Mishimoto Lifetime Warranty, including accident protection.
Is this radiator a good fit for a daily driver, or only for track use?
Both. The increased cooling capacity benefits daily-driven WRX owners dealing with warmer climates or stop-and-go traffic, as well as lightly modified or track-driven builds where engine temperatures run higher under sustained load.
Does this radiator require any tuning after installation?
No. A radiator upgrade does not affect fueling or require a tune. It is a direct mechanical improvement to cooling capacity.
