High-Performance Dual-Row Aluminum Core
At the heart of the Mishimoto MMRAD-BRZ-13 is its dual-row, high-density aluminum core, which provides up to 35% greater cooling capacity than the OEM radiator. The larger core volume and fin density allow more coolant to flow while dissipating heat faster, keeping intake and cylinder temperatures stable even during aggressive driving.
Performance Highlights:
-
❄️ Up to 35% better heat dissipation compared to stock
-
💨 Lower coolant temperatures during sustained high-RPM operation
-
⚙️ Reduced heat soak under track and drift conditions
-
🔥 Improved thermal efficiency for turbocharged or supercharged setups
Whether you’re running a naturally aspirated FA20 or a boosted build, this radiator ensures consistent cooling and smooth power delivery.
100% TIG-Welded Aluminum Construction
Unlike stock radiators that use plastic end tanks and crimped seams, the MMRAD-BRZ-13 is constructed entirely from TIG-welded aluminum, offering superior strength and longevity.
This means no more cracking, warping, or leaking under pressure — just a reliable, long-lasting radiator that performs under any condition.
The all-aluminum build also improves heat transfer and reduces overall weight compared to heavier copper/brass units, giving your car a cooling and performance edge without compromise.
Direct OEM Fitment — Easy Bolt-On Upgrade
The Mishimoto MMRAD-BRZ-13 radiator is engineered for a direct bolt-on fit for the following models:
-
Subaru BRZ (2013–2020)
-

-
Scion FR-S (2013–2016)
No cutting, trimming, or modifications are needed. It uses factory mounting points, fans, and hoses, making installation simple and seamless. This design allows you to replace your stock radiator with minimal effort — and maximum results.
Built for Street, Drift, and Track Use
Whether you’re daily driving or spending weekends at the track, the Mishimoto MMRAD-BRZ-13 is designed to perform. Its improved coolant volume and high-efficiency fins help maintain optimal operating temperatures under the toughest conditions — from stop-and-go traffic to full-throttle circuit racing.
