PERFORMANCE ALUMINUM RADIATOR KIT, FITS TOYOTA GR SUPRA 3.0L, 2020+

When it comes to keeping the Supra cool, it's a team effort. True, the primary radiator is the team captain, but if you recall from our first post, the cooling strategy for the B58 means every component is a key player. To make sure the entire team plays well together when you put the hammer down, we gave the same special attention to the auxiliary radiators. Our production samples are in, so let's take a look at the new design.

On the whole, these radiators received the same treatment as the primary unit. For starters, we ditched the plastic end tanks in favor of full aluminum units, which are TIG-welded to the core instead of crimped. This method of construction will result in a more durable and long-lasting radiator. Speaking of durability, we also designed these auxiliary radiators to accept the factory stone guards to avoid any potential punctures due to road debris. Couple that with our robust strutted tubes, and

When it comes to athletes, it's all about continuous improvement. Tireless training, coupled with the latest gear, ensure that athletes stay on top of their game. When it comes to the petrol-powered athlete that is the A90 Supra, the Mishimoto primary radiator is essentially a combination of the two, building the car's endurance with a shiny new piece of gear. Before we dive into how the new radiator performs though, let's take a look at our primary radiator production sample.

The most obvious improvement over the stock Supra primary radiator is the total lack of plastic on the Mishimoto replacement. As we covered in the last post, we ditched the plastic end tanks in favor of an all-aluminum design. This construction method significantly improves the radiator's durability by replacing the crimped-on plastic end tanks with TIG-welded aluminum, minimizing potential future leak points. That also means every connection and

Despite its simple appearance, improving upon the stock 2018+ Jeep Wrangler JL transmission cooler will take some clever engineering. In many cases, the solution to extracting more efficiency from a heat exchanger is to make it bigger, but with the cramped cooling stack of the JL, the size of our cooler would be limited.

In our last post, we looked at the stock 2018+ Jeep Wrangler JL transmission cooler and its home in the 2.0L Wrangler. Our performance trans cooler will fit all of the available engines and the 2020+ Gladiator, but the complexity of the 2.0T's cooling stack makes it the perfect R&D vehicle. That complexity also restricts how much we can change the dimensions of the transmission cooler.

With the stock transmission cooler removed, we measured the space it occupied and calculated how much larger our cooler could be. The length of the cooler is effectively fixed by the line connections on the passenger side and the mounting tabs on the driver's side. In the vertical plane,

When we were 16, our cars were our tickets to freedom and endless possibilities. For many of us, those early days of driving were the basis for a lifetime of automotive passion. It didn't matter if we were driving our dream car or our grandmother's 1991 Buick Regal, as long as we were behind the wheel with our friends in the back.

Somewhere along the road from 16 to adulthood, we lost that sense of freedom. Room for friends has been replaced by space for the kids and their bikes. Gas mileage now supersedes a killer sound system in the hierarchy of features. "How comfortable will this be on my 45-minute stop-and-go commute," has taken the place of "Will my crush think I'm cool in this?"

But growing up doesn't have to be all car seats and MPGs. Many vehicles, like the 2018+ Jeep Wrangler JL, have the power to make us feel 16 and free from responsibility again. Ever since its great grandfather, the CJ, fought its way back from World War II, the Wrangler has been a symbol of fervent freedom.

It's strange the path that automotive technology takes sometimes. Typically, it's a trickle-down effect. Top-tier race vehicles and techno-packed supercars are first in line for the latest and greatest gadgets. In the case of the dual-clutch transmission, it was a VW Golf (well, technically an R32) that was responsible for the trickle-up of the modern DCT into sports cars, like your F8X M3 or M4. Even with a non-conventional path to the M3, the Getrag paired with the S55 still needs to regulate temperature to operate to its true potential.

Why does the transmission temperature on the F80's DCT matter? Simply put, the excess heat can wear the oil in the transmission prematurely, which diminishes the oil's lubrication properties. The DCT is, in essence, a clever combination of an automatic and manual transmission. However, instead of a torque converter, there is a pair of clutches that split duties between the gear ratios, most commonly split between odd and even gears. These clutches are

When it comes to sports cars, sometimes the real joy doesn't come from a monstrous motor with oodles of power, but rather something small and nimble. A car that lets you utilize every horsepower and push it to the absolute limit. The NC MX-5 Miata defines that category. Sure, it might only have 170 hp, but you can use every single one, and effectively too. Thanks to its double-wishbone front and multilink rear suspension setups, the NC is more than capable of transporting you to the ragged edge with the wind in your hair and a grin on your face matching the Miata's front fascia.

But, there's always a downside, and in the case of the NC Miata, it comes as heat. Like any car, the Miata was designed to be driven. The spirit of the Miata lends itself to being driven hard, which makes it even more likely to experience high temperatures. Luckily, we here at Mishimoto are hard at work devising a better means of coolant temperature regulation.

The NC Miata follows the same design language as many
