Koyorad is proud to announce an all-aluminum high-performance radiator for the 5th Generation (2010-2020) Toyota 4Runner with 4.0L V6. Koyorad’s high density HyperCore measures 36mm thick, a 33% increase over the OEM unit which boosts the cooling system’s heat capacity and endurance under extreme use. With TIG welded all-aluminum tanks, this radiator is a long-lasting upgrade and perfect replacement for an aged and brittle OEM plastic tank radiator. Designed for serious off-road enthusiasts, the internal automatic transmission (AT) cooler has been purposefully omitted. An external transmission cooler (not included) will be necessary, which allows for visual inspections of the cooler itself and can be upsized and upgraded to offer improved transmission performance in the field. Since the internal AT cooler has been removed, the radiator will have zero risk of coolant and transmission fluid breech which can cause catastrophic engine and drivetrain damage. Advanced engineering and design, impeccable TIG welds, proficiency in furnace brazing, and triple pressure testing for quality has earned Koyorad the excellent reputation in performance cooling worldwide.
• All-aluminum construction with 36mm high density slim HyperCore
• No internal AT cooler eliminates the chance of coolant and transmission fluid breech on AT vehicles
• TIG welded and furnace brazed for strength
• Includes OEM style plastic side brackets for a direct fit
• Manufactured and triple pressure tested in Koyorad’s private ISO 9001 certified factory
• 2010-2020 Toyota 4Runner 4.0L V6 (5th Generation) *See Notes for Auto Transmission vehicles

New Koyorad Product Announcement
After nearly 30 years of supplying charge cooler cores to the Japanese market, Koyorad is proud to introduce their Universal Tube and Fin Intercooler HyperCores 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 HyperCore intercooler is manufactured in Koyorad’s private ISO 9001 certified factory.
• Proven in Japan’s D1GP, D1SL, D1 Lights, Formula D Japan, and MSC Challenge series

Koyorad continues to improve upon cooling performance for EG and EK chassis Honda Civics and is proud to announce a brand new full-length aluminum racing radiator for these “golden era” favorites. This application was taken from the Koyorad Japan catalog, proven for nearly a decade in Japanese N1 and Honda VTEC One Make Racing and is now available in North America. Designed for the serious race car, this radiator will not fit vehicles equipped with air conditioning (AC). By utilizing the space for the AC condenser, the radiator core surface could be increased by over 100%, which boosts the cooling system’s heat capacity and endurance in extreme conditions. The original radiator fan shroud and OEM DOHC radiator hoses can be used, requiring no modifications for installation. Users may install an aftermarket coolant temperature gauge with the optional 1/8PT sensor port, conveniently located directly on the upper radiator tank which eliminates the purchase of a sensor hose adapter. Koyorad’s advanced engineering and design, proficiency in furnace brazing, and triple pressure testing for quality has earned their excellent reputation in performance cooling worldwide.
Applications: 92-00 Honda Civic 1.6 DOHC Manual Transmission, not equipped with AC
Notes: Optional mount provided on lower driver’s side of radiator if additional support is desired.
