As the Toyota GR Corolla enters its third model year, we’ve been hard at work expanding our lineup of performance products for the rally-inspired machine. The 1.6 liter three-cylinder G16E-GTS engine is the highest power-per-liter output of any Toyota road car engine with each cylinder responsible for 100 horsepower, boasting a total of 300 horsepower out of a remarkably small engine. The engineers at Toyota’s Gazoo Racing Division achieved this feat by pairing the G16E-GTS with a turbocharger capable of 26.3 psi of boost.

In the blog about our Performance Radiator for the GR Corolla we talked about how important cooling is for one of the most powerful three-cylinder engines in history. The same is true for the GR Corolla’s intercooler system. The turbocharger is a vital part of the GR Corolla’s performance, and when you’re driving the car how it's meant to be driven—setting lap times at the track, carving up and down mountain roads, or spirited cruising down your favorite backroad—that

Picture yourself on the shoulder of the highway. You noticed the gears slipping a few miles back but decided to ignore it because you were only a few miles from home. Those slipping gears turned into violent lurches, and before you knew it, your 2019+ RAM 6.7L Cummins was sporting a Christmas tree dashboard and that dreaded burnt smell. Your transmission is toast.

But it didn’t have to be this way—if you had the Mishimoto Performance Transmission Cooler, you’d have made it home.

Our new transmission cooler for the 2019+ RAM 6.7L Cummins is a direct-fit application that offers improved cooling capabilities and seamless integration into your truck’s transmission system. Our cooler’s core is 64% thicker than stock and uses three additional rows of fins for peak efficiency. To maximize the cooling potential of the enlarged core, our engineers decided to use high-efficiency internal fins that add more cooling

Every owner of a performance vehicle knows the importance of keeping their car running cool, but not everyone knows where to start when it comes to upgrading their cooling system. For owners of the 2024+ Ford Mustang looking to take the next step in performance and reliability for their car’s cooling system, it’s best to start with the basics—the coolant expansion tank.

The stock coolant expansion tank on the 2024+ Ford Mustang leaves a lot to be desired. The plastic construction isn’t just an eyesore, it’s not designed to stand the test of time. After repeated heat cycles the plastic yellows and becomes brittle, leading to a higher risk of cracking and coolant leakage. This risk only increases when the vehicle is driven hard, such as fast laps at the track or hard pulls on the dragstrip.

Thankfully, we have a solution for Mustang owners out there.

For truck owners who depend on their vehicle for work, reliability and performance are paramount. Whether your truck is a construction fleet vehicle or a dedicated tow rig, one of its greatest enemies is heat — especially when it comes to the transmission.

Transmissions can generate a lot of heat, especially when towing, driving in rough conditions, and off-roading. This becomes more of a problem when they’re paired to a powerful engine, such as those used in GMT800 and GMT900 trucks, which is why we’ve been hard at work developing our Performance Transmission Cooler for the 1999-2013 Chevy Silverado and GMC Sierra.

Using the same tried-and-true core design as our K2 and Duramax trans coolers, our transmission cooler for the 1993-2013 Chevy Silverado and GMC Sierra boasts a 521% increase in core volume and 278% increase in frontal area compared to stock. The stacked-plate core

Following the immense success of the rally-inspired GR Yaris overseas, Toyota’s Gazoo Racing division needed an offering for the North American market. After years of work—including delays brought on by Toyota CEO Akio Toyoda, who wasn’t initially satisfied with the prototype—their result was the Toyota 2023 GR Corolla. Sharing the unique 1.6 liter three-cylinder G16E-GTS engine with the GR Yaris, the GR Corolla puts out an impressive 300 horsepower and 273lb-ft of torque.

So, what does having one of the most powerful three-cylinder engines in history mean? Well, it means you’re in for a lot of fun. But it also means when you’re driving hard, you’ve got to keep that straight-three engine cool. That’s why we’ve been hard at work developing the aluminum Performance Radiator for the 2023+ Toyota GR Corolla.

Our engineer, Mitch, started off by ditching the stock radiator’s plastic end tanks for a more reliable aluminum construction.

When Nissan planted the powerful VR30DDTT 3L V6 engine with twin turbochargers in the Nissan Z, there wasn’t much room left in the engine bay. The cramped area didn’t allow enough space to accommodate the traditional top-and-bottom-split airbox design, so they created a unique single-piece airbox with vertically inserted panel filters that maximized flow while minimizing size.

As enthusiasts and engineers, we tipped our hats to appreciate the work Nissan did with this design. But we couldn’t help but ask ourselves—how can we make it even better?

Our engineer, Ye, set out to design a direct-fit airbox for the 2023+ Nissan Z with these goals:

• Achieve better airflow than stock
• Ensure a direct-fit, bolt-on installation
• Create a design that lets the user alternate between a sealed or open airbox setup
• Deliver a high-quality intake tone
• Maintain a safe air-to-fuel ratio and ability to run on a stock tune

She began by inspecting and removing the stock airboxes to determine

When it hit the market in late 2022, the new Nissan Z turned heads. Released as a replacement for the Nissan 370Z, the 2023 Z featured a fresh, sleek new design with a 400 horsepower engine that could do 0-60mph in 4.3 seconds. The only problem? Due to international chip shortages and production bottlenecks, they were almost impossible to find.

Buyers who got their hands on a new Nissan Z count themselves among a lucky few. While the Z is a vehicle meant to be driven fast and hard, it’s understandable that owners might be hesitant to risk damaging a car that they worked so hard to get—especially since the new Nissan Z comes with a plastic oil pan.

To lessen these concerns, we set out to develop a layer of protection that would give Z owners the confidence to drive aggressively. The result of these efforts is the new direct-fit Engine Skid Plate for the 2023+ Nissan Z.

From the factory, the Nissan Z doesn't come with an engine skid plate, also known

We’re entering the fourteenth year of production for Ford’s 5.0L Coyote V8 engine, and in that time the Coyote has made a name for itself. It’s a powerful, throaty engine that’s been in the Mustang GT since the 2011 model year. Since its inception, the folks at Ford have managed to squeeze an extra 68 horsepower out of the Coyote with the new 2024 Mustang GT boasting 480 horsepower. Despite these gains, one issue the Coyote has had for years still persists—excessive blow-by.

If you’re not familiar, blow-by is a result of high pressure on the top side of the piston pushing combustion gasses, as well as droplets of oil and fuel, past the piston rings and into the crankcase. To prevent excessive pressure in the crankcase, most modern vehicles extract blow-by via the PCV system and route it back into the intake. While most manufacturers add an air-oil separator to the PCV system, they often aren't as effective at removing oil as we might like. This leads to the problem of oil
