Good product but prepare for hard work

Good quality product, looks good and works well. NOTE: The core of this wheel is approximately 3 times thicker than an OEM turbo cooler, so do not trust the factory reps to fit a Mazdaspeed Miata (stock turbo and air conditioning). You MUST do some modifications and amazing work. ie: the fan shroud tabs need to be trimmed, you need to shave some sections of the fan shroud motor support legs to expose the intercooler tubes and/or lower radiator hose, and move the A/C condenser forward as much as

Pros
  • TIG welded aluminum heatsink with high pressure protective cap and magnetic drain plug
Cons
  • Out of fashion

Pros
