Radiator
KOYORAD All Aluminum High Performance Radiator
Backed by over 70 years of cooling expertise, KOYORAD All Aluminum Performance Radiators are engineered to outperform OEM cooling systems for street, track, and racing applications. Available in multiple core thickness and density configurations, each radiator features premium Nocolok brazed aluminum construction for superior durability, heat dissipation, and direct-fit installation whenever applicable.
8 Types of Radiator Core Sizes
NOCOLOK R Brazing
State-of-the-art Nocolok furnace brazing permanently bonds the tubes, fins, headers, and brackets into a single high-strength structure, enhancing durability and resistance to vibration, road debris, and the elements.
Precise Tube and Fin Alignment
Precise tube and fin alignment, maintained through strict quality control, maximizes coolant flow efficiency and heat transfer performance.
Billet Filler Neck
Precision-machined billet filler neck provides enhanced strength, durability, and superior sealing under high-pressure conditions.
OE Mounting Compatibility with KOYORAD Design & Hand-Crafted Heliarc Welds
Engineered by KOYORAD to retain OE mounting points for precise fitment and straightforward installation.
Hand-crafted heliarc welds create a strong aluminum-to-aluminum bond, delivering exceptional strength and race-proven durability.
N Flo Technology
N-FLO Dual Pass Technology features welded internal partitions that force coolant to circulate through the radiator core twice, increasing coolant dwell time and heat dissipation. The result is improved cooling efficiency and greater thermal control for high-performance applications.
Oil Cooler
Universal Oil Coolers
KOYORAD Universal Coolers are advanced drawn-cup style heat exchangers designed to be lightweight, durable, and highly efficient. They are engineered to cool a variety of automotive fluids, including transmission, power steering, engine oil, and differential oil.
Featuring versatile -10 AN ORB ports, they easily adapt to AN fittings or push-lock barb setups for flexible installation.
Built with the same precision and quality as KOYORAD All Aluminum Racing Radiators, they deliver reliable performance for demanding applications.

Intercooler Core
Intercooler Cores
After nearly 30 years of supplying charge cooler cores to the Japanese market, KOYORAD is proud to introduce their Universal Tube and Fin Intercooler Hyper Cores to North America. KOYORAD has been providing cores to well-known in-house tuning, motorsports and performance divisions of major Japanese OEMs. KOYORAD's own extruded Tube and Fin Intercooler Cores have proven their performance in professional competition series such as D1 Gran Prix, D1 Lights, D1 Street Legal, Formula D Japan, MSC Challenge, and many others.
Extruded tube and fin intercooler cores are recognized for their balance of strength, high efficiency and up to 50% in weight savings over bar and plate coolers, not to mention their distinctive good looks. Rounded tube faces offer vastly improved ambient air penetration in comparison to flat faced bar and plate cores which result in efficient charge air heat transfer, and are less prone to heat-soak. The improved ambient air pass-through also helps the AC condenser, radiator and other fluid coolers function at their peak performance. KOYORAD's excellent reputation in performance cooling is a result of quality being the highest priority. Like every all-aluminum racing radiator, each Hyper Core intercooler is manufactured in KOYORAD's private ISO 9001 certified factory.
Features:
- Proven in Japan's D1GP, D1SL, D1 Lights, Formula D Japan, and MSC Challenge series
- Universal applications, end tanks not included
- All-aluminum, extruded tube and fin construction
- Promotes ambient air penetration, no “brick wall” effect of bar and plate cores
- Lightweight, up to 50% less weight than similar sized Bar and Plate intercooler cores
- KOYORAD Japan corporate logo stenciled on single side of core
- Manufactured in KOYORAD's private ISO 9001 certified factory
- Crossflow Configuration

KOYORAD Radiator Caps
Maximize cooling performance with the genuine KOYORAD Hyper Cap. Rated at 1.3 kgf/cm² (18.9 psi / 130 kPa), it raises coolant boiling point and improves heat resistance in high-performance applications.
Recommended for use with KOYORAD All Aluminum Performance Radiators (where applicable). Manufactured in Japan for durability and reliability.
Why is increased Pressure Better?
Increasing system pressure raises the boiling point of coolant. Most modern vehicles use a 0.9 bar radiator cap, while the KOYORAD Hyper Cap is rated at 1.3 bar, significantly increasing heat resistance.
This raises the coolant boiling point to approximately 267.8°F, nearly 56°F higher than water's normal boiling point.
By increasing the boiling point, the cooling system gains greater thermal capacity, helping maintain stable temperatures and improved performance under demanding conditions.
