PWR North America Radiator

Race-Bred Cooling for the Street, Track, and Beyond

PWR North America — originally founded as C&R Racing in 1988 — has built its reputation by engineering cooling solutions for the most demanding motorsports environments on the planet. Their radiators carry genuine racing DNA, developed alongside programs in NASCAR, IndyCar, NHRA drag racing, and IMSA sports cars before being adapted for performance street builds. When you shop PWR North America radiators, you're not getting a rebranded commodity part — you're getting hardware engineered to the same standard as components used in top-tier professional racing.

What Sets PWR North America Radiators Apart

The engineering differences start at the core. All PWR radiators, including the core, are manufactured by hand in state-of-the-art facilities in the USA, using high-grade aluminum with a unique wider dimpled tube configuration and a revolutionary louver fin design angle that maximizes cooling efficiency and heat disbursement.

These aluminum radiators feature a reinforced race fin design cross-braced for maximum strength and durability, developed using PWR North America's current F1 and NASCAR cooling technology. The proprietary R-fin technology adds another layer of real-world toughness: the hemmed leading edge creates a stronger fin so debris can't easily fold it over — a critical advantage for off-road and racing applications where foreign object damage is a constant threat.

PWR radiators can be up to 30% more efficient than standard OEM units, with varied core combinations available using 26, 32, 42, 55, and 68mm tubes. PWR cores are epoxy-free and furnace-brazed, TIG-welded by experienced racing fabricators, with fittings and necks that are CNC billet machined, and tanks, mounts, and shrouds that are CNC-punched and hand-formed.

A Radiator for Every Application

PWR North America's radiator lineup spans a wide range of use cases. Their radiators cover applications ranging from Formula 1 to sprint and circle track racing, to off-road racing, as well as high-performance vehicles such as the Subaru WRX/STI, Chevy Camaros, and the Ford F-150 Raptor.

• Racing Radiators: Options include 55mm drag racing radiator modules, 42mm late model racing radiators, and universal performance radiator modules — many paired with SPAL fans and shrouds for complete cooling solutions.
• Universal Performance Radiators: PWR's universal radiators are capable of cooling many applications and come standard with a 42mm thick core utilizing rolled dimpled tubes with an engineered V-shape fin, available in either single or double pass configurations as well as open or closed system designs.
• Off-Road Radiators: Off-road cores use extruded tube and R-fin technology for durability, with the extruded tube allowing for higher pressures in the cooling system while maximizing heat rejection.
• OEM-Fit & Application-Specific Radiators: PWR offers application-specific options like the "Weekend Warrior Spec" radiator for the FL5 Civic Type R and DE5 Integra Type S, built for drivers who push hard on weekends while maintaining daily usability.

PWR North America's Late Model Dirt and Pavement radiators also feature a new 36mm core technology that fits more rows of tubes and fins in the same height, allowing for a thinner core that improves airflow through the core. Whether you're chasing lap times or building a reliable high-performance street car, the PWR North America radiator catalog has a solution engineered — not just assembled — for your needs.
