Megan Racing - Subaru WRX/STi 02-07 Radiator – MR-RT-SI04ST

High-performance driving, such as racing or drifting, dramatically increases engine temperature. This puts considerable strain on your vehicle's cooling system. Megan Racing Aluminum Radiators are designed to combat this issue by providing a highly efficient cooling solution, ideal for high-performance and spirited driving.

Upgrading to an aluminum radiator can lead to a noticeable temperature drop of 20 degrees or more, ensuring your engine stays cool and preventing overheating during competitive events. The all-aluminum construction, from the tanks to the core, offers enhanced durability over the factory plastic radiators, which are prone to cracking and leaking as they age. The larger heat-exchanging core not only improves heat dissipation but also increases coolant capacity, enhancing overall engine performance.

This radiator comes with a 1.1 BAR radiator cap for efficient pressure regulation and is compatible with OEM fans, making installation simple. ATTN: It’s essential to flush the radiator and remove any air pockets before installation to avoid overheating due to low coolant or air trapped in the system.

NOTE:

• 2002-2003 Subaru Impreza WRX models only have one radiator cap on the coolant reservoir. For 2004+ models, Subaru added a second cap to improve system filling. Please make sure to purchase the correct radiator for your specific application.
• Some modification of the stock fan shroud mounting holes may be required for proper alignment.
• For 2002 WRX models, leave the cap closed. Ensure the correct radiator is selected for your application.
• The upper radiator hose may need modification for fitment with the larger radiator. Specifically, trimming or cutting the hose may be required to accommodate the increased size. Measure carefully before making any cuts to avoid errors.
