Mishimoto 90-97 Mazda Miata 3 Row Manual X-LINE (Thicker Core) Aluminum Radiator

This Mishimoto aluminum radiator upgrades 1990-1997 Mazda Miata manual transmission models with a 3-row X-LINE design featuring a thicker 60mm core for enhanced heat dissipation. It replaces the factory radiator to lower engine temperatures during track days or spirited drives while maintaining direct OEM fitment. Engineered with 100% brazed aluminum construction, it delivers reliable cooling without modifications.

Key Features

  • 3-Row X-LINE Thicker Core: 60mm thick core (19.69" x 12.60" x 2.36") with 1.25" tubes provides greater cooling capacity than stock 2-row units.
  • 100% Brazed Aluminum Construction: TIG-welded end tanks resist corrosion and cracking common in OEM plastic tanks for long-term durability.
  • Direct OEM Fitment: Bolts directly into 90-97 Miata engine bay with 1-1/4" inlet and outlet fittings, no cutting or adapters needed.
  • Included 1.3 Bar Cap: High-pressure cap maintains optimal system pressure to prevent boil-over and improve coolant flow efficiency.
  • Polished Aluminum Finish: Clean, durable surface enhances underhood appearance while protecting against road debris.

Product Notes

  • Designed exclusively for manual transmission Miatas. automatic models require MMRAD-MIA-90A.
  • Pair with Mishimoto silicone hose kit for complete cooling system upgrade.
  • Ships in protective foam-lined box to prevent fin damage.

Installation Notes

  • Professional installation recommended.
  • Drain coolant, remove OEM radiator, and bolt in new unit using factory mounts in under 1 hour.
