There are several mods that you can do to improve your 7.3L powerstroke engine. You can improve the fuel pump, injectors, enlarge the turbo, put in a wide band O2 censor, and several other modifications.
Below, we have listed 4 of the best mods for 7.3 Powerstroke engines. There are other things that you can do as well, but these are cost efficient and will help immensely. Below, we will talk about things to look for when you are trying to modify your engine.
S&B Filters Cold Air Intake for 1998-2003 Ford Powerstroke 7.3L
The S&B Filters 75-5062 cold air intake is the perfect way to maximize fuel efficiency and engine power in a 1998-2003 Ford.
This cold air intake is designed to lower the temperature of the air that combines with your fuel in your 7.3L Powerstroke. This makes the air more dense, which means it can hold more oxygen. Then, once the air is rich with oxygen, it produces a more explosive result when it sparks with your fuel. This is what gives your Powerstroke even more power than usual!
The cold air intake allows 53.66% more airflow compared to the factory model, and it’s 99.37% efficiency. The whole unit is made of silicone as well to ensure it won’t melt, rust, or fluctuate with extreme temperatures. It’s also important to note that this cold air intake meets the legal standards in all 50 states for use in street-legal Powerstroke vehicles.
If you’re looking for a new addition to your Powerstroke to make it even more explosively powerful, then the S&B Filters 75-5062 cold air intake is for you! I would definitely add this to the list of the best mods for 7.3 Powerstroke that you would want to make to your engine.
Bosch 69136 Original Equipment Replacement Electric Fuel Pump
Another good modification to your 7.3L Powerstroke is a fuel pump. The Bosch Electric Fuel Pump is a great mod for your engine. The turbine pump design nearly eliminates any fuel pulsation. Not only that, but the impellor ring allows the fuel to run smoothly.
The spin-balanced and polymer-encased armature will reduce excess noise and vibrations. Also, this fuel pump is extremely durable! The premium carbon brushes will help it last longer without service. This fuel pump utilizes advanced materials, so it can have a longer life then other fuel pumps.
The noise suppression coil also eliminates any radio frequency interference. You can replace the fuel pump for a decent cost. Modifying this piece will increase the effectiveness of your vehicle and its fuel output. This is one of the top cheap 7.3 Powerstroke mods (cheap in price only, not quality).
DieselSite Billet Turbo Compressor Wicked Wheel 2 for 94-03 Ford Powerstroke 7.3L
This is one of my favorite modifications for the 7.3 Powerstroke. It affects the turbo of the engine. This product is a best seller, and it has stellar ratings from users. The wicked wheel will increase performance of your engine. It will also help the drivability of your vehicle.
It is a very simple but yet very effective upgrade (see full specs). The wheel is easy to install as well. The wicked wheel will give you a boost to your turbo. This mod is more effective when you get other mods with it. However, it can stand on its own.
The wicked wheel is also balanced at the factory, which will save you some time and effort. It is a WW38. I would suggest this mod for anyone that is looking to up their turbo efficiently. This will do the trick.
HEUI Injector for Ford 7.3 Powerstroke or International T444E (Number 8 injector on limited number of vehicles)
Finally, I would suggest upgrading the HEUI injector. Ford trucks did not have an injector pump during the lifespan of the 7.3L powerstroke engine. Each one of these injectors are their own injector pump in a way. It helps with the use of oil and fuel, which should never mix unless there is a big error.
This mod can help improve the flow of oil and fuel throughout your vehicle. Therefore, I would put it as a top priority for any diesel engine. This particular one would be great for your vehicle for many reasons.
They are backed by first class technical support. Therefore, if you are having issues with anything, you can always get help fairly quickly. This product is also backed with a 13-month unlimited mileage warranty. Therefore, you will not have to worry about going over mileage if you drive for long distances at a time.
The injectors (see full specs) are also made in the United States, which is a plus. Alliant Power Products are reliable and are a good brand to help you modify your engine. I would use them if you are looking to replace the HEUI injector. Hands down, these are among the best mods for 7.3 Powerstroke engines on the market.
The Best Upgrades for 7.3L Powerstroke Engines: What To Look For
Overall, you should look for items that will improve the quality of your engine. The 7.3L Powerstroke is not the most environmentally friendly engine. Therefore, environmental mods would be good if you are looking to cut down on the emission.
I would also suggest looking at items that are going to help out with fuel. You do not want to burn through fuel if you are driving your vehicle consistently. Therefore, making sure the fuel pump and injectors are solid would be a great place to start.
Getting a wide band O2 Censor will also help with some of the emissions. Look for modifications that are going to benefit your car the most. There are several different forums that give advice on different modifications you can do to your engine.
I would suggest comparing products and going for the best quality. All of the items listed above are some of the best quality parts you can get for your truck. Finally, I would look for durability. Working on cars is fun, but not when the same part keeps breaking. Therefore, getting parts that will last a long time will do you a favor in the long run.
Overall, there are several upgrades that can qualify for the best mods for 7.3 Powerstroke engines. We listed some suggestions that we believe would benefit your vehicle. However, forums are also a great way to find other modifications you can do to benefit your 7.3L Powerstroke engine. Good luck!
