Review on 🚘 Mishimoto MMRAD-MIA-99 Performance Aluminum Radiator for Mazda MX-5 Miata (1999-2005) by Doug Layman

Revainrating 4 out of 5

Not a direct replacement for the 2004 Mazdaspeed Miata; Well designed, well packaged

You can find this information elsewhere on the web but this cooler is not a direct replacement for the 2004-2005 Mazdaspeed Miata. What I ended up doing was: bending the AC condenser brackets, sawing off part of the condenser case, sawing off the fan cover, enlarging the hole on the left radiator bracket, cutting off the gasket/sleeve to mount the condenser and repositioning my flying Miata -Inlet on the throttle body. . What would have been 45 minutes of work on a direct landing turned out to be more like 5 hours of work. The welds on the radiator are clean, it holds pressure, it looks good in the bay. I'll never have to worry about plastic earplugs being put on me again. However, the fan shroud posts on the heatsink are about twice as long as they should be, causing the entire fan shroud to protrude an inch or more from the bay, squeezing an already cramped area and the heatsink itself being thick enough to rub against. Capacitor if no clearance measures are taken. 5/5 stars for build quality, 2/5 stars for installation. If I were to do it again, I'd buy the Koyo, which I understand is coming out right away (at a $100+ premium).

Pros
  • Fits Mazda Miata 1999-2005 Owner's manual
Cons
  • Poorly thought out
