7.3 parts upgrades that fit, function, and go easy on your finances...
The 7.3 Powerstroke is considered by many to be the best Ford diesel engine ever made.
7.3 OEM engine parts were built to last hundreds of thousands of miles and endure tough everyday use.
But despite its legend for longevity, to keep your 7.3 diesel motor at peak performance, you'll still need to replace a few parts over the course of its lifetime.
Using quality OEM and aftermarket replacement parts your truck will last that "hundreds of thousands of miles" you keep hearing about. And if you're upgrading parts for your 7.3 engine, you'll want get the best price vs. performance parts you can afford.
But whichever one you choose to do — install new stock parts or bolt on performance parts upgrades — finding OEM and aftermarket parts that perform doesn't have to bankrupt you.
Reliability... That's what we're after.
Not all off us want to get maximum performance from our 7.3. Many of us are happy when our truck starts and runs all day long.
For us, finding the "right" part means getting a part that fits, functions, and provides predictable and reliable behavior from our truck.

How parts make it on this list:
I test the parts on my own 2002 7.3 Powerstroke...
Most of the parts I recommend to you, I've already purchased and installed on my 2002 Ford F250 7.3 Powerstroke Diesel.
My definition of a quality part you should use on your 7.3 is one that installs correctly and performs the way it's supposed to … for a long time.
I do the research for you...
You'll get the benefit of all the research I conduct on OEM and aftermarket parts. I search Ford, Amazon, Ebay, BuyAutoParts.com, and several other diesel engine parts suppliers to compare parts details, shipping times, and prices.
I dedicate an average of 5-10 hours on each 7.3 part:
I try to do the legwork that I know you'd do if you had the time.
I scour the reviews...
I read all the available parts reviews for you, paying particular attention to any reviews below 3 stars as well as how many "3-word" reviews there are. Because some bad reviews aren't necessarily about the part and some 5 star reviews aren't all that useful either.
I also check the dates on all the reviews to see how the most recent ones compare to the early ones. It's been my experience with aftermarket parts is that manufacturers usually get better over time.
However, if a particular part listing looks like its on a downswing in reviews, I kick it off the list. But at the end of the day, individual reviews vary widely with all parts and what works horribly for one person may be fantastic for another.
I only show you the "best" part...
The way I choose parts for my own truck is likely the way you do:
I select a part for you that has the best mix of quality, price, review rating, and performance.
I try to make it easy...
Once I approve a part to be on my list, I gather all the information I can and present it to you in an easy and accessible format.
All individual 7.3 parts pages and the two "7.3 Parts List" pages contain:
Then I add it to either the 7.3 Powerstroke Replacement Parts list or the 7.3 Performance Upgrades List. You get a very clear way to find out more information about that part and a transparent link that will take you right to it.
I write a detailed review for you...
Finally, I provide you with a comprehensive parts review on each part.
The good, the bad, and the ugly truth about my experience or the general consensus on a particular part.
