Mishimoto 1999-2005 Mazda Miata Manual Performance Aluminum Radiator (MMRAD-MIA-99)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1999-2005 Mazda Miata models including Base, LS, SE, 10th Anniversary, Shinsen, and Mazdaspeed.
The Mishimoto Performance Aluminum Radiator (MMRAD-MIA-99) is engineered as a direct-fit upgrade for the NB-chassis Miata. Designed to replace the failure-prone factory radiator, which often suffers from brittle plastic tanks and seam leaks, this unit features 100% brazed aluminum construction and TIG-welded end tanks for superior durability under heat and pressure.
Equipped with a high-efficiency 2.05-inch thick dual-core, this radiator provides up to 30% better cooling capacity over standard OE units. Whether for daily driving or track use, the increased fluid capacity and improved heat dissipation help maintain lower engine temperatures and prevent overheating. Each radiator includes a high-pressure Mishimoto radiator cap and polished end tanks for a professional finish in the engine bay.
- Direct fit for 1999-2005 Mazda Miata (Manual transmission only)
- Full aluminum construction with durable TIG-welded end tanks
- 2-row, 2.05-inch (52mm) thick brazed aluminum core
- Includes Mishimoto high-pressure radiator cap
- Precision-engineered for OEM mounting points
- Manufacturer Part Number: MMRAD-MIA-99
