  • Polished Tank Ends: TIG-welded end tanks with polished finish ensure leak-free performance and clean appearance
  • Direct OEM Fit: Matches factory inlet/outlet positions at 1.5 inches for plug-and-play installation on manual transmission Miatas
  • 1.3 Bar Cap: High-pressure radiator cap raises boiling point to prevent overheating and maintain system pressure
