Product Description
Koyorad HH060643N High Performance Radiator
About This Item
Introducing the Koyo HH060643N 89-92 Mazda RX-7 1.3L FC NATurbo MT N-FLO Technology Radiator! If you're a serious performance tuner looking for a radiator that delivers unmatched cooling performance, then look no further. The Koyo HH060643N is specifically engineered with a 48 millimeter high density core + dual pass, making it perfect for both circuit and daily use. One of the standout features of this radiator is its increased capacity, which means better cooling reserve when you need it most. With the ability to double your coolant capacity, you can expect up to 35 percent increased performance over your stock radiator. Koyorad's N-Flo Technology takes cooling efficiency to the next level.
By allowing the coolant to remain in the radiator for a longer period of time, this innovative design transfers more heat to the surrounding air, resulting in optimal cooling performance. This technology is particularly beneficial for cars that have limited airflow to the radiator. Durability is a top priority for Koyorad, and that's why they use NOCOLOK Brazing in all their racing radiators. This process ensures maximum strength, anticorrosion protection, and a strong bond between fins and tubes.
With over 50 years of experience in manufacturing OE replacement radiators, you can trust in the consistent high quality and durability of Koyorad products. Installation is a breeze with the Koyo HH060643N Radiator. Designed as a direct bolt-in replacement for your Mazda RX-7 1.3L (both Turbo and Non-Turbo models), there's no need for any engine modifications. Plus, it retains the mounts for the stock fan shrouds and fans, ensuring a seamless fit. Upgrade your cooling system and take your performance to the next level with the Koyo HH060643N 89-92 Mazda RX-7 1.3L FC NATurbo MT N-FLO Technology Radiator.
