Upgrades can make a world of difference, but only if you choose the right ones. With that out the way, here are the most efficient aftermarket parts for the 7.3 Powerstroke engine:

01. GlowShift – Boost & Temperature Gauges – Best Overall

Furthermore, you can change the color of the gauges. And regardless of the color you choose, you’ll still be able to make out the gauge readouts.

Another feature we love is that no matter what color you choose, they’re still pretty visible at night.

They’re not distractive at all, so you won’t feel dizzy taking a look as you’re going down the road.

We also really like that the needle glows read so that the driver can have a much easier time looking at the gauge readouts.

As far as the installation process goes, we’d say it’s pretty easy compared to other models we’ve come across up until now.

For example, they included a T-Fitting adapter, which can be installed without drilling.

“But it’s not all flying colors. Our biggest problem with this model is that the connections feel pretty cheap. They could’ve used more durable materials for the connections. That would’ve been perfect.”

The installation process for this cooler couldn’t be any easier.

This brand has made sure to include everything for the assembly process, so you won’t have to go to any hardware store.

What’s more, you don’t need to modify your vehicle to install it.

Consumers have also pointed out just how much of a difference this cooler has made.

For example, many drivers manage to reduce the temperature from 220 degrees to 170-160 degrees.

“The only thing we’re not so happy about is that they should’ve included a manual to install the transmission cooler. For beginners, this would’ve been the cherry on top. Nonetheless, that’s a minor inconvenience.”

Many aftermarkets reduce production costs by adding cheap materials. That’s not the case for this one.

Considering that this is an OE replacement, we can’t really complain.

What’s more, this model does a pretty good job of reducing hot-start issues.

If you’ve ever tried to start your car and it wouldn’t start no matter what, chances are, it’s related to the fuel.

When fuel cannot circulate, the vehicle will not start. This model will take care of this issue.

The quality of this model deserves some credit. It is made of aluminum, which is an excellent material for a reservoir tank.

You can probably throw a rock at it, and it will not damage the tank.

As a result, they’ve made this one corrosion-resistant so that the driver can sleep well at night knowing they don’t have to deal with it anymore.

This model is designed to replace OEM, but a better one. This means that it’ll fit right in, and you won’t have to move other parts around or modify your vehicle.

On top of that, we love the finish they used for this model. It looks pretty cool and won’t wear out as quickly as the stock one.

To prevent that, this model is made of silicone, which is an excellent material to increase pressure tolerance inside the hoses.

This way, you’ll avoid any blowouts in the future.

One of the most remarkable features this model offers is that it has a protective shield against oil.

As you might know, oil can do some nasty stuff to the hoses over time. With this one, you don’t have to worry about that.

What to Consider when Buying an Upgrade for 7.3 Powerstroke

If you have no idea how to go about choosing the best upgrades for 7.3 Powerstroke, here’s a helpful guide to get started:

OEM Quality

There are plenty of aftermarket products out there. And as much as they claim they’re pretty similar to OEM, they are far from perfect.

As a result, you’ll end with a bigger or smaller product than you initially thought.

To get around that, we suggest looking up the dimensions of the product. Any decent company should be transparent enough about their sizes.

This will allow you to pick up the right one, and you won’t have to modify your vehicle for it to fit in.

Gauges

If you’re planning on adding a turbo to your vehicle, you need gauges to know how much boost you’re getting.

But as good as they are, you have to know a few things. First, the needle should glow red.

This way, you can easily see the boost you’re getting. This step is vital as some needles can be hard to see, especially at night.

Second, they should dim up at night. Driving at night can be challenging for some people.

And looking at your gauges as you’re going in a dark place is certainly not the most straightforward task. As such, your gauges should dim up to 30% more at night.

Finally, any set of gauges you plan on getting should be UV-protected.

Keep in mind that they’re constantly exposed to the sun. So, it’s not out of the question to think they will eventually get damaged.

Electric Fuel Pump

Want to get rid of your old manual fuel pump and get an electric one? Well, you should be aware of a couple of things.

Any decent electric fuel pump should mitigate or get rid of hot-start issues.

What’s more, they should also reduce any noise. Finally, it should also get rid of annoying radio frequency interference.

Reservoir Tank

The reservoir tank, that little tank, that pretty much nobody changes. But if you’re in the market for a new replacement, you need to make sure it is made of aluminum.

This is pretty much the go-to for anybody who wants a new reservoir tank. It holds up pretty well, and chances are you won’t have to replace it any time soon.

Finally, your new reservoir tank should be transparent. Regardless of the finish you choose, you should still be able to see through it.

Otherwise, you won’t be able to make out the fluid levels without removing the cap.

Aftermarket Transmission Cooler

Any high-end transmission cooler should lower your vehicle’s temperature from 220 degrees to 170 degrees.

That’s the sweet spot for most engines. And what you should aim for when getting a new aftermarket cooler.

Moreover, make sure the hoses fit your vehicle nicely. Sometimes, they’re not the right length, and you’ll have to cut them, which is somewhat annoying.

Your transmission cooler should also be designed for towing. Transmission coolers do not increase towing capacity.

However, they do help cool down the engine. Keep in mind that towing puts a lot of pressure on the engine, which can be harmful.

Towing a trailer or carrying heavy loads for hundreds of miles can overheat the engine.

As a rule of thumb, get a transmission cooler with a decent gross vehicle weight rating.

For example, a decent one would be a model that supports up to 20,000.

Silicone Radiator Hose

As you might know, rubber radiator hoses are pretty weak and don’t hold well to heat.

When this happens, your engine will overheat, and it might start leaking coolant. To prevent that, get a silicone radiator hose.

These radiator hoses are more likely to get dirty after a couple of weeks. But they sure are strong compared to the rubber ones.

In addition to that, make sure they’re oil-resistant. Radiator hoses and oil don’t get along too well. So, watch out for that.

Turbo Upgrade

The 7.3 Powerstroke engine is one of the most reliable engines in the market to this day.

Any driver with this engine knows that pretty well. However, there are certainly better options nowadays when it comes to horsepower.

To get around that, drivers tend to install turbos. The main objective of that is the increase of power.

However, it requires a lot of work to install one, as you might need to install other aftermarket parts for it to work.

Instead, get a turbo compressor wicked wheel from Diesel Site. This model is pretty much plug-and-play.

Cold Air Intake Upgrade

There’s just so much you get by getting a better cold air intake.

And as crazy as it might sound, spending that much money on a cold air intake to get that sweet whooshing sound is definitely worth the money.

But as great as that sounds, you still need to keep a few things in mind when getting a better cold air intake.

The first thing you should consider is the material. It should be made of durable heat-resistant materials.

Don’t forget that it’ll be exposed to lots of heat under the hood.

So, if you want it to be by your side for many years to come, it should be able to withstand high temperatures.

The intake should also be waterproof. Now it’s pretty rare when water gets inside. So, chances are you’ll never get to experience that.

But if you ever drive it through high water, you’re not going to have a fun time. Water getting inside can lead to terrible engine issues in the long run.

Finally, consider the shape of the air intake. Curved intakes have a much harder time keeping up with your engine.

Since it is curved, air can’t flow freely, whereas a straight cold air intake is more efficient when it comes to airflow.

Best Upgrades For 7.3 Powerstroke: Buying Questions

For more information about the benefits you get from upgrading your 7.3 Powerstroke engine, consider checking this section out:

How much horsepower can you get from a 7.3 Powerstroke?

You can add more power to your 7.3 Powerstroke engine and make it sound ferocious. However, you can only do so much.

Depending on how many aftermarket parts you add to the engine, any horsepower is subject to change—for example, a water-methanol injection, flow downpipes, a transmission cooler, and so on.

All of these aftermarket parts are designed to improve horsepower. But some of them might need additional mods to work correctly.

Does a transmission cooler really help?

Yes, a transmission cooler does make a huge difference. Overheating engines are a concerning problem among drivers.

Installing a transmission cooler would allow you to reduce the abnormal heat significantly.

What’s more, vehicles don’t have enough transmission cooling to cool down the engine.

And if you have a truck and plan on towing heavy loads for thousands of miles, a transmission cooler would help cool down the engine during that trip.

How much does it cost to rebuild a 7.3 Powerstroke?

There are plenty of brands out there that sell turbo kits. One of the most noticeable ones is Xotic Exhaust.

You can get a brand-new turbo kit from them for roughly $100.

The installation process is relatively simple, and there are several videos out there showcasing the technique.

But if you take the vehicle to the local mechanic, expect to pay about $800.

When doing this, the fluid level might drop, and you should see bubbles inside. Once it is running, and you can see steam, top it off.

How can I get more power out of my 7.3 Powerstroke?

There are hundreds of ways to get more power out of the 7.3 Powerstroke engine.

One of the most well-known methods is to upgrade the old turbo.

And if you’re willing to spend more money on upgrades, consider getting a DP tuner.

Finally, you should also a transmission cooler to get more power out of the engine.

How can I improve my 7.3 Powerstroke gas mileage?

Upgrading your throttle body should improve gas mileage. This is a simple installation and is not as expensive as adding aftermarket mods.

What’s more, you can clean the throttle body, and your gas mileage should improve.

Do cold air intakes really make a difference?

Yes, upgrading your cold air intake will make a difference. They can help the system pull in as much air as possible, which results in more horsepower.

In addition to that, you’ll have a much easier time towing with a high-performance cold air intake.

But if you’re willing to spend that much money on a cold air intake, we suggest getting lighter wheels and better tires.

They will make a more considerable difference than the intake alone.

Conclusion

The best upgrades for 7.3 Powerstroke will make your riding experience way more enjoyable, and you’ll get more power out of your old engine.

That said, we did plenty of research before settling for any of the upgrades covered above.

The 7.3 Powerstroke engine is powerful, but you can’t just put anything on it. We hope you can now make your machine more efficient.
