Performance Radiator for Acura NSX (1990-2005) 3.0L 3.2L

High-Capacity Performance Radiator for 1990-2005 Acura NSX

What it Does: Replaces the aging factory cooling unit with a high-capacity, all-aluminum core designed to significantly lower coolant temperatures during spirited driving and track sessions.

The Stock NSX Cooling Limitations

The factory radiator equipped in the NA1 and NA2 chassis relies on a plastic end-tank design crimped to a relatively thin aluminum core. Over decades of thermal cycling, these plastic tanks become brittle, leading to micro-cracks, pressure loss, and catastrophic coolant leaks at the seams. Furthermore, the OEM core thickness is often inadequate for maintaining stable operating temperatures during extended high-rpm track use or aggressive canyon driving. Once heat soak sets in, the ECU pulls timing to protect the C30A or C32B engine, actively reducing horsepower and torque output. This thermal inefficiency limits the vehicle's endurance and reliability in demanding driving conditions.

The Engineering Solution

This performance radiator resolves original equipment flaws through robust, TIG-welded all-aluminum construction. By eliminating plastic end tanks, the risk of seam failure under pressure is completely mitigated. The 26.77 x 13.39 x 1.26-inch core provides substantial fluid capacity and surface area for superior heat dissipation. Precision louvers and fins maximize airflow dynamics, drastically accelerating thermal exchange. This efficient design ensures the V6 block maintains optimal temperatures, preventing heat-induced timing retard and preserving consistent power delivery lap after lap. Direct-fit 1.5-inch inlet and outlet ports guarantee a seamless installation with factory or aftermarket hoses.
