Upgrade cooling capacity with a thicker, high-efficiency radiator that supports track days, hot climates, and tuned engines without overheating.

$730

The GREDDY TRUST Aluminium Racing Radiator TW-R for Mazda RX8 Series 1 models (2003–2008) is engineered specifically for rotary heat management, providing significantly improved cooling capacity and stability in demanding conditions.

  • High-capacity all-aluminium core enhances heat dissipation compared to the OEM radiator
  • Reduces coolant temperatures during hard driving, track work or hot climate use
  • Lighter than the standard unit, contributing slightly to weight reduction at the nose
  • Direct-fit design for RX8 Series 1 (2003–2008) using factory mounting points and hoses
  • Developed specifically for rotary applications with GREDDY’s motorsport experience

You will appreciate more consistent coolant temperatures and reduced risk of overheating, giving your Series 1 (2003–2008) RX8 greater reliability on spirited runs and track days.

For a more complete cooling package, consider pairing this with SAMCO Silicone Coolant Hose Set for Mazda RX8 (Series 1 & 2, 2003-2012) and AUTOEXE Strut Tower Bar for Mazda RX8 (Series 1 & 2, 2003-2012).
