Keep your miata cool with our radiator and airflow solutions.\u003c\/p\u003e","products":[{"product_id":"flyin-miata-crossflow-radiator","title":"Flyin' Miata crossflow radiator","description":"\u003cp\u003eWe've taken our crossflow radiator back into the shop to see if it could be even better than it already was. The filler cap is no longer on a neck, it's now right on top of the tank - which gives much faster filling than having it cantilevered out off the tank. It's a cleaner look and better fitment (especially on MSMs). It also has an honest drain, not a small drain squeezed into a compromised location. \u003c\/p\u003e\n\u003cp\u003eFor manufacturing, we worked with Koyo, who brings well over half a century of experience to the table, to see what could be made better. Working with Koyo means that the latest version of our crossflow is manufactured by Koyo (not a third-party), has beautiful TIG welds, micro-welded O tubes (stronger and more reliable than B tubes), and NOCOLOK brazing for maximum durability and anticorrosion protection. We then use Koyo's Hypercore, which increases the effective surface area - i.e., the radiator's ability to shed heat. Finally, each radiator is individually leak tested three separate times to ensure no issues. To top it off, we back it up with an exceptional two-year warranty. \u003c\/p\u003e\n\u003cp\u003eBut even though we're taking advantage of Koyo's manufacturing, it's nothing like the generic Koyo radiator you find elsewhere. The crossflow design, the drain, the core selection and the unique mounting setup in the car all set it apart.\u003c\/p\u003e\n\u003cp\u003eNow that you know why the new crossflow is the best one ever, why do you want a crossflow in the first place? In short, dramatically improved cooling. The coolant flows side-to-side instead of top-to-bottom, which means that it's in the radiator core (and shedding heat) for longer. Not only is the layout much better, the core itself is special - in our extensive testing (read more about it \u003ca href=\"https:\/\/help.flyinmiata.com\/en_us\/whats-cooler-than-cool-B1vyGy3QK\"\u003ehere\u003c\/a\u003e), not only did we find that generic upright aluminum radiators weren't much better than stock, we also found that dense tube and fin counts, as well as narrow fin widths, cooled best. So that's what this radiator uses. We also found that while a thicker than stock radiator is better, there's absolutely such a thing as too thick - eventually, the thicker core just means more resistance to air flowing through the core, plus the air is so hot by the time it gets to the back of the core it's not doing any good anyway. A thicker radiator makes a better heatsink, but you're not looking for something to absorb the heat, you're looking for something to shed it. Ours hits the middle ground nicely at 36mm \/ 1.4\" thick. You won't find a radiator that's better at shedding heat than this one. Mate it with our FM coolant reroute and our Stage 2 V2 brushless fan kit, and you'll have the ultimate cooling setup.\u003c\/p\u003e\n\u003cp\u003eWe also designed the radiator to fit all 1990-05 Miatas, with the only difference being some brackets. There is no modification required to install the radiator in the car - the factory mounts are re-used in NAs (no new NA mounts are included, you must reuse yours), new upper mounts (with stock lower mounts) are required on an NB. A new high pressure (16 psi) radiator cap is included, and you can use any cap designed for a Miata.\u003c\/p\u003e\n\u003cp\u003eIf you choose to retain the stock fans, you'll need to make modifications to their shrouding. We highly recommend using one of our Airflow Kits for multiple reasons. May not fit with all intake systems - please call us to confirm. Does NOT fit with a TDR intercooler on a supercharger. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNB cars will need our upper bracket kit (not necessary for NAs). NB cars using stock fans will need our NB fan bracket kit as well.\u003c\/strong\u003e Add those parts to your cart above.

Our long-standing relationship with Spal and our ability to create a complete solution means we can bring them to Miata owners!\u003c\/p\u003e\n\u003cp\u003eSo what's the advantage? First, the fan has a variable speed and an intelligent controller so it can deliver as much or as little airflow as required, from a slight whisper to a hurricane. It's tied into the coolant temperature, so it can anticipate problems and prevent the car from getting hot in the first place. This means less electrical draw and more power available at the wheels when the car is at normal temperature. It also avoids a big startup surge that can drag down your electrical system for a moment or blow fuses. In fact, it's so subtle you may never actually notice when they're running most of the time.\u003c\/p\u003e\n\u003cp\u003eWhere they really shine is their ability to pull through multiple heat exchangers. Most fans are rated at zero (not even atmospheric*) pressure, which is completely irrelevant. You have a radiator and maybe an intercooler and possibly an AC condenser and maybe even an oil cooler all stacked up in front of the fan, so it's having to pull hard to get air through that stack. A standard radiator will give about 0.5 inH2O of pressure at the fan and it only goes up from there. You can see from the chart how our brushless kits stack up. These motors are strong. They're also built to military specifications, so they're highly waterproof and vibration resistant. Naturally, it's mounted on a custom shroud with bypass flaps. The bypass flaps allow us to take advantage of airflow coming in through the mouth of the car (allowing the fan to spin slower or not at all) and decreasing the restriction of the shroud if the incoming air is greater than what the fan can pull.\u003c\/p\u003e\n\u003cp\u003eSo what's with the single fan variant? Well, by going with a single fan we can also go with a large diameter fan. These high-torque brushless fans are quite deep, and the central location of the single fan helps quite a bit with fitment. It also cuts down the cost fairly significantly. When we looked at the numbers, we saw that it slotted really nicely in between our Stage 1 kit and the Stage 3 - so our single fan experiment became the Stage 2.\u003c\/p\u003e\n\u003cp\u003eThis kit will fit with \"normal\" installs of our turbo kit and front sway bar, but if you have extra \/ bigger parts in front of the engine (e.g., a giant sway bar) it's a good idea to check clearance. This fan is about 2.25\" (measured straight \/ horizontally back) from the fan mounting bosses at the sway bar. It's mounted at an angle, so it's a bit less at the bottom and a bit more at the top. \u003c\/p\u003e\n\u003cp\u003eThis airflow kit will not work on cars with the factory Mazdaspeed intercooler piping. This kit will also not work with factory intakes that have resonators hanging off of them - basically, if anything is close (horizontally) to your existing fans this kit will very possibly interfere. Bear in mind that this kit protrudes the same distance from the radiator in all places (as opposed to stock fans that have good clearance top and bottom but are deeper in the middle). Please reach out if you have any specific questions and we'll make our best guess. \u003c\/p\u003e\n\u003cp\u003eCertain ECUs such as the Hydra and MS3 can control the fans directly so they do not require the standalone controller. Stock ECUs, MS2 and the FM221 will require the controller (\"brain kit\"). The fans will not work without PWM control of some sort. Please note that if you need the brain kit, you also need a place to mount its sensor (3\/8\" NPT hole) - our hose splice kit below is an easy way to add a hole for the sensor. \u003c\/p\u003e\n\u003cp\u003eFitment on a turbo car without a coolant reroute will be challenging and will require modification of the shroud and very tight packaging. We strongly recommend using this fan kit on a car with a reroute.\u003c\/p\u003e\n\u003cp\u003eThe downflow variant includes a 3D-printed bracket for mounting the shroud to radiators with stock-style NB driver-side lower fan mounts. Note that stock-style radiators intended for automatic cars will need to have the transmission cooler fittings removed to avoid interference with the shroud. When used with an automatic car, some modification of the shroud will be required to clear the cooler fittings.\u003c\/p\u003e\n\u003cp\u003e*Fans are rated at \"not even atmospheric\" pressure? What? Yeah. When a fan is rated at a certain CFM at zero pressure, any pressure that the fan has to work against is evacuated from the test chamber. Put another way, the fan is literally 0% efficient at that point. Your ceiling fan is working against higher pressure (atmospheric) than a cooling fan in that test scenario.\u003c\/p\u003e\n\u003cp\u003eThere are those who say that you don't need fans (or anything more than stock fans) or a shroud - and they're not necessarily wrong. If you only have a radiator (e.g., no AC condenser or intercooler), you have ducting to ensure almost all of the air entering the mouth goes through the radiator, improved evacuation (e.g., hood vents), and the car is always operated at speed, you probably don't need much or anything in terms of fans. However, if you have a stock body (no hood louvers, nothing more than basic ducting), and\/or a stack of heat exchangers, you operate the car at slow speed (e.g., a tight track) or in traffic (whether on track or on the street), your need for improved airflow increases. Higher power, combined with the factors above, means you need that much more airflow from your fans as well. For example, NASCAR uses electric fans since they're typically in tight traffic, but F1 cars (with their typically cleaner air and infinitely-engineered airflow) don't. Also, bear in mind that we use bypass flaps to give the best of both worlds - minimal restriction from the shroud when the air coming into the mouth of the car is of a sufficient velocity, but proper sealing so the fan pulls across the entire surface of the radiator when the fan pulls more than what's coming in through the mouth. In a real world experience, on a turbo street car with AC on a tight track, this setup  allowed us to stay out about twice as long as any other fan setup.\u003c\/p\u003e\n\u003cp\u003eWe recommend the installation of our \u003ca href=\"https:\/\/flyinmiata.com\/products\/brushless-ac-fan-control-kit?_pos=2\u0026amp;_sid=1d05f34a9\u0026amp;_ss=r\" target=\"_blank\" title=\"Brushless AC fan control kit\" rel=\"noopener\"\u003eBrushless AC fan control kit\u003c\/a\u003e\u003ca href=\"https:\/\/flyinmiata.com%20%E2%80%BA%20products%20%E2%80%BA%20brushless-ac-fan-control-kit\" title=\"Brushless AC fan control kit\"\u003e\u003c\/a\u003e if you run AC, otherwise this monster fan will always run at 100% speed when the AC is on. \u003c\/p\u003e\n\u003cp\u003ePlease note that a radiator is not included.\u003c\/p\u003e","brand":"Flyin' Miata","offers":[{"title":"Non-crossflow radiator \/ With fan brain \/ With hose splice","offer_id":43458793013503,"sku":"09-5621X~OE~BR~SP","price":989.99,"currency_code":"USD","in_stock":true},{"title":"Non-crossflow radiator \/ With fan brain \/ No hose splice","offer_id":43458793046271,"sku":"09-5621X~OE~BR~X","price":935.0,"currency_code":"USD","in_stock":true},{"title":"Non-crossflow radiator \/ No fan brain \/ With hose splice","offer_id":43458793079039,"sku":"09-5621X~OE~X~SP","price":740.99,"currency_code":"USD","in_stock":true},{"title":"Non-crossflow radiator \/ No fan brain \/ No hose splice","offer_id":43458793111807,"sku":"09-5621X~OE~X~X","price":686.0,"currency_code":"USD","in_stock":true},{"title":"Crossflow radiator \/ With fan brain \/ With hose splice","offer_id":43458793144575,"sku":"09-5621X~XF~BR~SP","price":992.99,"currency_code":"USD","in_stock":true},{"title":"Crossflow radiator \/ With fan brain \/ No hose splice","offer_id":43458793177343,"sku":"09-5621X~XF~BR~X","price":938.0,"currency_code":"USD","in_stock":true},{"title":"Crossflow radiator \/ No fan brain \/ With hose splice","offer_id":43458793210111,"sku":"09-5621X~XF~X~SP","price":743.99,"currency_code":"USD","in_stock":true},{"title":"Crossflow radiator \/ No fan brain \/ No hose splice","offer_id":43458793242879,"sku":"09-5621X~XF~X~X","price":689.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/3914\/9055\/products\/09-56216_crossflow_stage2_v2_fan_kit_052220-7_1.jpg?v=1664989815"}],"url":"https:\/\/flyinmiata.com\/en-ca\/collections\/spring-cooling.oembed","provider":"Flyin' Miata","version":"1.0","type":"link"}
