Description
We've spent a lot of time testing cooling systems on our dyno, and this is one of the spinoffs.
We started with a laser-cut aluminum shroud to maximize efficiency of the fans. It ensures that all the air gets pulled through the radiator - and we mounted the shroud far enough away from the radiator to make sure the whole core gets air. Some of the shrouds on the market are far too close to the rad, meaning that only about half of the core gets airflow. We also added some flaps that allow air to bypass the shroud at high speed without affecting the draw of the fans. The shroud is made with threaded inserts to make life easier and comes with spacers to ensure proper standoff from the core.
A pair of Spal fans were chosen not only for their flow, but their ability to pull air through a stack of heat exchangers such as an intercooler and A/C condenser. Most fans are rated for their flow at 0 pressure and their performance drops off rapidly as they have to work harder. Not these! They're also low-profile enough to clear most intercooler piping. The end result is a compact package that does an excellent job of cooling high-power Miatas. They're not slim-line fans and pull a fair bit of power - but that's because they have the torque to get the job done.
There are other fan/shroud combinations on the market, but none of them have the same dyno-proven ability to pull large amounts of air through your radiator - and A/C condenser and intercooler, if applicable. Do your homework and don't get fooled by cheap alternatives.
Our Stage 1 kit pulls about 1200 CFM at 0.5 inH2O of pressure (the minimum pressure for a car with only a radiator, no condenser, intercooler, etc.), and is low-profile enough to fit almost anything. Yes, it will fit the Mazdaspeed Miata.
For non-crossflow radiators only. There's a special kit for crossflow radiators.

I recently installed these fans in addition to performing a coolant exchange and thermostat swap. All I can say is WOW!!! I removed a set of (brand redacted) due to insufficient flow after having a near-miss in traffic one hot Saturday. In the overwhelming heat of south Louisiana, I've yet to see my coolant temperature hit 200, with air-con running and a comfortable (for a miata) cabin. 10/10 HIGHLY recommend! Yes I love the roar of these things too!
Good fitment.
Two opportunities to improve.
1. The stock wiring harness is a 4-wire and this kit is 2-wire. Improve by making this true plug and play.
2. One of the fan motors makes a squeeking noise when operating; not loud enough to justify removing, returning and reinstalling another, but not the quality of manufacture we're expecting from our good friends at Flyin' Miata.
Plug and play would definitely be easier, but the MSM is a low volume car and the fan wiring is a little goofy. We'll check into a plug and play setup as time allows, but we can't guarantee anything.
The squeaking noise is strange and shouldn't be happening. Maybe there's contact somewhere? We've reached out to try to resolve this, but haven't heard anything back yet.
Got one to replace the fans on a MSM, if your MSM fans fail you will find out there are none left in stock anywhere. Installed behind a Koyo and it looks great and works like a champ in lower Alabama in the summer hard driving and getting stuck in traffic.
Alabama Summer, Little Enchilada, long grades in the mtns. Equals a Water temp gauge rising. Installed Stage one onto an already installed Koyo 36mm radiator. Water temps now stabile, plus A/C seems to be cooler. I did have to reduce spacing away from Radiator on Passenger side due to interference with intercooler tubing. I recommend this product.
