Koyo is proud to introduce an all aluminum performance radiator for the 1970-1978 Datsun 240Z, 260Z, and 280Z with manual transmissions.  Koyo engineers have designed some unique features into this brand new model.  Unlike the traditional downflow style of the OEM Datsun radiator, the Koyo performance radiator is manufactured with a robust 53mm crossflow core design.  Another unique feature is the integrated 1/8” NPT female accessory fitting located near the top inlet tube.  This fitting (supplied with a threaded plug) will accept a 1/8” NPT temperature sensor supplied with most aftermarket temperature gauges, or may even accept a coolant line for aftermarket turbochargers.  Every Koyo All Aluminum Performance radiator is engineered in Japan, precision welded and polished by hand, and are a direct fit in the vehicle’s factory location for an easy installation.

Koyo’s global reputation for high quality cooling products begins with the selection of the finest materials.  Koyo privately owns each factory, never outsources their manufacturing and overseeing each stage of production using Japanese made equipment throughout the production of each radiator.  Koyorad All Aluminum Performance Radiators are hand assembled, precision TIG welded, and triple pressure tested throughout the manufacturing process contributing to reliability and uniformity.  The superior quality of Koyorad all aluminum radiators will take your vehicle’s engine performance to the next level.

Koyorad announces the soon to be released 2009-2010 Hyundai Genesis 2.0L Turbo MT All Aluminum Radiator (Koyorad #VH13120) with Koyorad exclusive “Hyper V” high efficiency 36mm core.

With assistance from the Hyundai /Kia America Technical Center, and Genesis tuners, Koyorad has track tested this design extensively in the Southern California heat with outstanding results.  Like all Koyorad All Aluminum radiators this is a high quality, hand-made product, designed by our very own engineers in Japan.  Development was made with real-world track conditions and feedback from, then finally manufactured and packaged in Koyorad’s privately owned factory in Indonesia.

Hyundai chose to mount their intercooler underneath the radiator structure, therefore our developers in Japan paid special attention to the reinforcement and placement of these brackets to assure precise fitment and long term durability to avoid street or trackside mishaps.   You will also notice our engineers have placed a true 90 degree independent filler neck placed high up on the passenger side tank (instead of incorporating the filler neck into the tank itself) in order to extract the most cooling efficiency from the Koyorad cross-flow radiator core.   There may be other Genesis radiators available at this moment, however Koyorad VH13120 will be worth the wait!  This item will be available shortly, stay tuned for updates!   Genesis 3.8L V6 MT owners… be prepared for the release of an All Aluminum Racing radiator for this vehicle as well!

Koyo New Release – New Universal Engine Oil Coolers (EOCs)

Koyo is proud to announce the universal Engine Oil Cooler (EOC) after a collaborative effort with the Japan, Singapore and US offices.   For many years in Japan, Koyo custom oil coolers have proven their effectiveness during competition in D1 Gran Prix and D1 Street Legal on our sponsored vehicles.  These purpose-built drift cars are subject to indirect and inconsistent flow of air, occasional contact between vehicles, and high oil pressures, therefore they require superior build quality and high heat transfer efficiency from the radiators and EOCs.  The Koyo Universal EOC is extremely well built, beautifuly polished, highly efficient, and tough in order to be resilient to flying road debris.  We spent several months consulting with industry experts to determine an acceptable core size, proper fittings, and best mounting options before introducing this to the US market.

Each Koyo All Aluminum EOC is assembled and TIG welded by hand in our privately owned ISO-9001 compliant factory in Indonesia.  You can expect the same level of precision and attention to detail as with our all aluminum racing radiators, since they are all made within our Koyo factoryKoyo EOCs feature our N-FLO (Dual Pass) Technology to ensure the highest efficiency, within the tightest of engine confines.  Unlike some oil coolers on the market, Koyo EOCs incorporate -10 AN fittings for the inlet and outlet, therefore allowing users the option of stepping down to control oil flow according to their needs, eliminating the use of metric-to-AN adapter fittings.  These carefully designed female AN fittings will properly accept both -10 AN type O-rings and crush washers for the best seal possible.  When you’ve invested so much into you engine, and function and quality is paramount, choose our all-new Koyo Universal EOC and use it in combination with a Koyo Racing Radiator for the best cooling system on the market.

Features

  • Advanced Extruded Tube and Fin design
  • N-FLO (Dual Pass) Technology
  • 2 x AN-10 Fittings (Accepts -10 AN O-rings/crush washers)
  • High luster polished finish
  • Red/Blue Koyorad Logo
