CUSCO Radiator Cooling Panel for Mazda RX8 (Series 1, 2003-2008)

Direct more air through the radiator with a formed panel that reduces pressure loss around the core, supporting more stable coolant temperatures.

$160

The CUSCO Radiator Cooling Panel for Mazda RX8 Series 1 models (2003–2008) replaces the OEM plastic trim at the top of the radiator support with a rigid aluminium plate to seal the gap and force more airflow through the radiator core.

  • Directs incoming air through the radiator instead of allowing it to escape over the top
  • Improves cooling efficiency, helping prevent overheating during hard or prolonged driving
  • Manufactured from lightweight aluminium with a durable, signature CUSCO blue finish
  • Installs as a direct bolt-on part using factory mounting points with no modifications

You will notice more stable coolant temperatures and improved confidence in your cooling system, particularly beneficial for track use or spirited runs in your Series 1 (2003–2008) RX8.

For maximum effect, pair this panel with the BEATRUSH Engine Cooling Under Panel Tray and the GREDDY TRUST High Pressure Radiator Cooling Cap.
