Duramax LM2, LZ0 Air-To-Water Intercooler Kit
Cooler and denser charge air is essential for diesel trucks. It directly impacts performance, efficiency, and engine longevity. That’s why your 3.0L Duramax deserves the PPE air-to-water intercooler upgrade.
The PPE intercooler utilizes an all-aluminum, bar-and-plate cooler core with durable cast-aluminum, TIG-welded end tanks. Unlike the factory crimped plastic end tanks, this design offers significantly improved heat resistance and handles turbo boost effortlessly. The PPE intercooler features a 2.4 times larger (140% increase) cooler core and highly efficient cooling fins in both air and coolant passages. The increased core size, combined with fluid-dynamically optimized end tanks, reduces air pressure drop by 77%, resulting in easier and smoother engine breathing and less turbo stress.
Our real-world testing showed that the intake air temperatures (IAT) followed the ambient air temperature very closely under various driving conditions. The IAT was reduced by as much as 30 degrees when compared to the factory-installed cooler in our back-to-back testing.
Keep your 3.0L Duramax performing at its best with the PPE intercooler.

Well pleased with the product. Very easy to install and the application is superb.

Just installed myself. Very easy without any complication. Put her in and then drove from Virginia to Wyoming and endured some pretty significant heat wave in the area and the temps of the truck remained low.

I highly recommend going on YouTube and watching demonworks do the install prior to installing. Take your time and its pretty straight forward, I was having an issue trying to get all the bolts started and realized the padding on top of the engine is what was holding me up. The bleeder nut made purging the system easy as well. Ive noticed a significant change in temps on the charge air cooler as well.

I am thrilled with this product - fit and finish are top notch, and I have noticed an 2-3 mpg increase in fuel mileage (I installed the PPE Zilla tube and airbox at the same time, as well as a new air filter, MAF, and MAP sensors, so it's hard to say exactly where most of the improvements came from). One thing PPE can do is improve the instructions, specifically where it mentions loosening the stud that holds the oil filler tube and wire loom - I had to watch Demonwork's YouTube videos to get clarification on this. Also, I highly recommend adding nickel anti-seize to the 13mm turbo bolt - mine almost got seized when reattaching and I came really close to snapping the bolt.

Installed my kit this morning (10/4/2025)
Took about 2 hours taking my time and going slow.
Kit is of great quality and very complete. Instructions were fairly easy to follow.
I gave it 4 stars, because no one is perfect!
PPE's customer service is the best!

Install took a little time, other than that was a piece of cake. This wakes the truck up especially if you have an aftermarket intake. Better mileage, more power, and super clean. Amazing piece!
J
Living in Central Texas, cooling is essential and this unit has helped significantly. Definitely seeing better fuel economy after installing this, the zilla intake, and exhaust - roughly a 10% increase. And the combo actually makes it sound a bit better too.
Z
It's as good as every PPE product. fairly easy install. It performs great and from what I've seen so far IATs are much lower
B
Went in pretty easy. I did have to sand a little bit of material away on the bracket due to the turbo rubbing and not allowing the bolt to go in, couldjust be an issue with the 2025s. Other than straight forward install. Made my son help so we got some quality time together.
B
The combination of the intercooler, Zilla pipe, S&B intake, and PPE cat-back exhaust significantly improves cooling and airflow, making it an ideal foundation for future engine tuning. It’s a must have!!!

Great addition to a truck , I just installed on my 25 3.0L
Simple to follow instructions and easy to install in short time .
Hoping this helps with avoiding long term issues with the smaller cooler. ( raw finish gives that factory look - after going back and forth on what one to get , I'm glad I went Raw ! )
Great quality !

We installed this intercooler on Saturday. The installation was easy. The fit was perfect, PPE did a great job designing this kit. When I test drove my truck I could feel the power and now I can spin the tires! Thank you PPE

Many people ask if it makes a difference at all. It absolutely does. Right away you can feel the engine just able to breathe easier and smoothly, helped with mpg as well, takes less throttle to achieve the same speeds as before and adds a bit more noise to the engine with the S&B intake I have sounds great.

“Finally got the intercooler installed looks super cool everyone that looks at it can’t believe it. The guy who did the installation keeps talking about how super nice the kit was and the intercooler itself. He works on Range Rover’s at his shop.”
