The last time we saw our 2015+ F-150, it was still equipped with the plastic bag of dinner rolls that is the stock expansion tank. Since then, we've been busy designing, prototyping, and sampling a stronger and better-looking expansion tank for all 2015+ F-150s. Before we dive into our tank and the progress we've made, let's look back at the stock tank and some of its shortcomings.

The expansion tank equipped to the 2015+ F-150 is fine enough for the average driver who spends most of their time looking at the outside of the truck or sitting in the cabin. For the enthusiast who spends hours under the hood, however, it presents a few problems. The clear plastic construction makes it easy to see how much coolant is in the tank, but it's not particularly attractive. If you've spent hours of your time washing the

What started in the late 1800s as a means of increasing the power and fuel efficiency of industrial engines, turbocharging has become abundant in every corner of automotive culture. Shortly after the first oil crisis in 1973, turbocharged vehicles grew in popularity as fuel-efficient alternatives to high-displacement engines. More than 40 years later, turbocharging has produced some of the most powerful and efficient vehicles the world has ever seen. Compared to those early vehicles, modern turbocharged systems are a complex network of piping, sensors, and heat exchangers that leverage every available ounce of technology.

As our volunteer truck rolled into the shop, Dan began gathering his tools for a short, and ultimately rewarding, install. Removing the intercooler was second nature to him and before long, the stock transmission cooler was sitting next to its former home. Our much larger, much better-looking replacement took up residence in the truck with only two bolts. After months of work, the test fit was complete.

Before we could begin testing, there were still a few final details to be worked out. You might notice that the lines fitted to our cooler are not the stock lines, and there's a good reason for that. The stock lines for the 2003-09 Ram utilize a quick-disconnect style fitting

There are two things that are guaranteed to get just about everyone at Mishi HQ away from their desk for at least a few minutes. The first is as soon as something new or unique rolls into one of the bays. It doesn't matter if it's a massive diesel truck, C6 Corvette, or one of the 10^th Gen Civic Hatchback Sports. Nearly everyone wants to get a close look at what we've brought in for R&D. The second thing that gets people shuffling through the shop is when that new car makes its way to our Dynapack system. Our conspicuously red FK7 was no exception. Everyone here was curious about how the scrappy L15B7 performs with a little help from Mishimoto, and I'm going to venture to guess that you are too.

No matter how many trucks I write about, I'm always surprised how often a critical part of the drivetrain is underdeveloped. It's even more surprising when a truck built for towing and hauling has a major flaw in the transmission system. The transmission is the heart of towing, and when you're asking it to carry over five tons of truck and trailer up a grade, any weakness in the system is sure to show itself. However, the Allison transmission mated to 2001-2014 Duramax engines is not that weak point.

At Mishimoto, we're constantly striving to improve our products and bring more value to our customers. That's why we've developed an update for our 2007-2018 Jeep Wrangler JK radiator. Our V1 Jeep Wrangler JK radiator has served as a substantial upgrade over the stock plastic radiator, but after hearing feedback from our customers, we wanted to push the limits even further.

With the off-road enthusiast in mind, Mishimoto has developed our V2 2007-2018 Jeep Wrangler JK radiator. This new radiator incorporates several updates that bolster the performance and durability of the Wrangler's cooling system.

As with many of our cooling products, this updated radiator provides a substantial size increase over stock. An 18% greater core volume, fin area, and external tube area, along with

At first, admittedly, it didn't look like we were flexing as hard as we could with the Focus RS. With our full PTU/RDU cooling kit installed, we extended the time on the track with all four wheels producing power by about three minutes. However, after some reassessment, Dan transplanted the PTU temperature sensor from the gear oil into the coolant stream, producing great prospects for a fully functioning AWD Ford Focus. Since it would be a while until we could take our RS to the track, we decided to reach out to a third-party tester known for thrashing their cars in the name of motorsport.

Motorsport is all about the challenge, and pushing your vehicle of choice to the limits. In the realm of racing, there are a myriad of different genres to challenge any car, but one especially stood out for the perfect test of Ford's sophisticated AWD system"rally stages.
