GReddy 92-02 Mazda RX-7 (FD3S) Aluminum Radiator TW-R - Front Mount

If you're pushing your 1992-2002 Mazda RX-7 FD3S hard, especially with engine modifications, keeping temperatures in check is crucial for performance and longevity. This GReddy TW-R aluminum radiator is designed to handle the increased heat load that comes with a performance rotary engine.

This is a front-mount radiator, meaning it sits in front of the intercooler and other components, which is a common setup for the FD3S chassis. The all-aluminum construction is key here; it's lighter than a stock radiator and offers better heat dissipation. GReddy uses a dual-core design (TW-R stands for Twin-Core) with a thicker core than many stock radiators, increasing the surface area for cooling. This means more coolant can flow through and shed heat more effectively, helping to prevent overheating during spirited driving or track use. The tank construction is also aluminum, TIG-welded for solid connections that resist leaks under pressure.

This radiator is a direct replacement for the stock unit, designed to fit the FD3S chassis without major modifications. It's a well-built piece that addresses a common weak point in high-performance rotary engines. While it's designed to fit the stock mounting points, you'll want to ensure all your coolant hoses and connections are in good condition before installation, as a new radiator can sometimes highlight issues with older rubber components.
