DNA Motoring RA-SRS13-2 Aluminum Radiator
Our DNA Motoring RA-SRS13-2 aluminum radiator is engineered for enthusiasts who demand maximum cooling capacity and reliability from their 2013-2017 Subaru BRZ or Scion FR-S. Constructed from lightweight, aircraft-grade aluminum with precision-welded tanks, this radiator delivers up to 40% better heat dissipation than factory equipment.
Direct-fit design means zero modifications required—just remove your stock radiator and bolt this one in using factory mounting points. We’ve tested each unit under extreme conditions to ensure it handles track days, spirited driving, and daily commutes with equal confidence.
Engineering & performance specifications
Aluminum Core Construction & Thermal Performance
The DNA Motoring RA-SRS13-2 aluminum radiator features a dual-row core design with 42mm thickness, significantly outperforming the factory single-row configuration. Aircraft-grade aluminum construction sheds heat faster than traditional copper-brass radiators while cutting weight by approximately 30%.
Each core tube is precision-formed to maximize surface area contact with coolant, while high-density aluminum fins pull heat away from the tubes and transfer it to passing airflow. TIG-welded end tanks eliminate weak points common in crimped designs, ensuring leak-free performance even under boost or extended high-RPM operation.
Direct-Fit Installation & Compatibility
OEM Mounting Points & Brackets
We designed the dna motoring ra srs13 2 aluminum radiator to match factory dimensions and mounting locations exactly. All pre-drilled holes align with your vehicle’s existing radiator support brackets, and inlet/outlet positions match the stock configuration for plug-and-play hose routing.
This radiator fits 2013-2017 Subaru BRZ and Scion FR-S models equipped with manual transmissions. Automatic transmission vehicles require a different radiator variant due to integrated transmission cooler lines. Installation typically takes 2-3 hours with basic hand tools—no cutting, welding, or custom fabrication required.
Performance Testing & Quality Assurance
Every DNA Motoring RA-SRS13-2 aluminum radiator undergoes a multi-stage pressure test protocol before leaving our facility. We subject each unit to 25 PSI hydrostatic pressure—well above typical cooling system operating pressure—to verify weld integrity and eliminate micro-leaks that could cause failures down the road.
Our real-world testing program includes extended sessions on road courses and dyno facilities, where we monitor coolant temperatures under sustained high-load conditions. The dual-row core consistently maintains temperatures 15-20°F cooler than stock radiators during back-to-back dyno pulls, giving tuners additional thermal headroom for aggressive calibrations.

Common Questions About the RA-SRS13-2 Radiator
This radiator is designed specifically for manual transmission models. Automatic transmission vehicles have integrated transmission cooler lines that route through the radiator, requiring a different part number.
If you have an automatic FR-S or BRZ, you’ll need the RA-SRS13-AT variant which includes fittings for the transmission cooling lines. Double-check your transmission type before ordering to ensure proper fitment.
The DNA Motoring aluminum radiator weighs approximately 8.5 pounds, while the stock copper-brass radiator weighs around 12 pounds. That’s a 3.5-pound weight reduction in the front of the vehicle, which improves weight distribution slightly.
Despite being lighter, the dual-row aluminum core provides superior cooling capacity compared to the heavier factory unit. The weight savings come from aluminum’s better strength-to-weight ratio, not from thinner materials or compromised construction.
No modifications are required—this is a true direct-fit replacement. All mounting holes align with factory radiator support brackets, and inlet/outlet positions match the stock configuration for plug-and-play installation.
You’ll reuse your existing radiator hoses, clamps, radiator cap, and overflow reservoir. Basic hand tools are all you need, and most DIY mechanics complete the swap in 2-3 hours including coolant fill and system bleeding.
Use a quality ethylene glycol-based coolant formulated for aluminum cooling systems, mixed 50/50 with distilled water. Avoid coolants with aggressive additives that can corrode aluminum over time.
Popular options include Subaru OEM Long Life Coolant, Zerex Asian Vehicle, or Prestone Extended Life. Always use distilled water rather than tap water to prevent mineral buildup inside radiator tubes. Total system capacity is approximately 7.5 quarts including engine block and overflow tank.
Yes, the RA-SRS13-2 is well-suited for forced induction builds. The dual-row core provides additional thermal capacity to handle increased heat loads from boost, and the unit is pressure-tested to 25 PSI—well above typical system pressure even with a high-pressure radiator cap.
Many customers run this radiator successfully with turbo kits producing 300+ horsepower. Pairing it with an upgraded oil cooler and high-flow thermostat further improves thermal management for high-performance applications.
Park on level ground with the engine cold and radiator cap removed. Fill the radiator completely, then start the engine and let it idle while slowly adding more coolant as air bubbles escape.
Run the engine until the thermostat opens (coolant temperature reaches operating range), then squeeze the upper radiator hose several times to help purge trapped air. Top off the radiator, install the cap, and check the overflow reservoir level. Recheck coolant level after the first drive once the system fully stabilizes.
Yes, this radiator is covered by our standard limited warranty against defects in materials and workmanship. The warranty does not cover damage from improper installation, accidents, or use of incorrect coolant.
Keep your purchase receipt and contact our customer support team if you experience any manufacturing defects. We stand behind the quality of every radiator we ship and will work with you to resolve any legitimate warranty claims promptly.
