AWR Racing uses Ron Davis Racing cores and builds 100% of the aluminum radiators sold by Mazdaspeed, including the ones for the Mazda 6. Additionally, the Protomotive Mazda 6 that competed in the 2005 Speed Vision World Challenge was built by AWR Racing and uses one of these radiators.

• Heavy-duty, all-aluminum radiator provides superior cooling for high performance applications.
• Bolts in stock locations.
• Race car performance and quality for your race car or street car.
• Completely constructed from aircraft quality 6061-T6 aluminum alloy.
• Fully tig welded fixture, built for accuracy.
• No epoxy bonding.
• Furnace brazed core.
• Exclusive multi-louvered fin design for exceptional cooling.
• No need to run outlandish thick core radiator.
• CNC-formed header tanks.
• Direct bolt-in design that requires no modification to any existing factory accessories or body work.
• Correct outlets and hardware bosses to accept factory fans and hoses.
• Race track and street proven.
• Pressure tested to 32 psi - far beyond actual cooling system safe operating pressures.

Some manufacturers of aluminum radiators specify how many BTUs their radiators are capable of shedding. AWR Racing does not perform BTU differential tests because it is impossible to make an accurate comparison due to all of the uncontrollable variables invloved. Please refer to the following article for further detail: http://www.awrracing.com/pages/btu.html

The radiator for the automatic transmission includes a stacked-plate transmission cooler, which is why there is an additional charge for that model.

We also offer the Stant radiator cap for an additional $29. The stock radiator cap can be used, but it is not recommended for high performance events. The Stant high pressure racing radiator cap holds 21-25 lbs operating pressure, allowing slightly higher temps without boiling over. This is highly recommended!

Radiators may be built to order depending on availability. Radiators that are built to order my take up to 3 or 4 weeks to ship from the time the order is placed.

WARNING: Zerex Supercleaner from Valvoline may corrode AWR Racing radiators. Therefore, it is strongly recommended to avoid using this or similar products to clean aluminum radiators made by AWR.
