Koyorad 36mm Hyper V Aluminum Racing Radiator NB Mazda Miata 1.8L 99-05

Koyorad 36mm Aluminum Racing Radiator 99-04 Miata (NB)

The Hyper V-Core Series is the newest to the Koyorad | Koyo All Aluminum Racing Radiator line up.  An engine's cooling system in many newer vehicles are suffering due to limited space and crowding which affects air circulation.  Our new ultra efficient Hyper V core was developed specifically for vehicles which see extreme heat, are limited in space, and where the factory inlet/outlet locations eliminate the option for a proper N-FLO design.   The Hyper V Series radiators have a specially designed fin and tube pitch which significantly increases its surface area while still allowing for excellent air circulation through the radiator.  The Hyper V-Core series is the perfect solution where space savings and high performance is a must.   Unless noted otherwise, all Koyorad Hyper V-Series All Aluminum Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the  stock fan shrouds and fans.  See notes in individual item descriptions for details.

All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications; however we recommend using aftermarket electric fans for the best results. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler; one can use the Koyo Racing Radiator with automatics for increased cooling capacity.
