Koyo R-Core Radiator w/N-Flow Nissan 180sx 1991-1999

Built with a robust 53mm core, the R-Core Series is
engineered for the serious performance tuner. 
Increased capacity means better cooling reserve when you need it.
Intended for both circuit and daily use, you may double your coolant capacity
and see up to 35% increased performance over your stock radiator.  All Koyorad R-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.

When factory equipped radiators have inlet and outlet locations
that allow proper placement, Koyorad carefully welds aluminum partitions in the
upper and lower tanks of the radiator. This is Koyorad's N-Flo Technology which
allows for a double or triple pass radiator. This design cools more efficiently
by allowing the coolant to remain in the radiator for a longer period of time
therefore transferring more heat to the surrounding air. N-Flo Technology is
available on cars that are known to have limited airflow to the radiator.
