2020-2026 GM 1500 3.0L - Zilla Carbon Fiber Intake Tube

Greatly improved airflow. Fits better than the factory box and it looks badass! If I ever need to remove it to get to the map sensor or the crankcase pressure sensor, as I mentioned, it is removed easy. Easy to clean too if there is any dirt or oil build up. Did I mention how bad **** it looks?!

I installed the PPE Zilla Intake Tube on my 2023 Chevy 1500 Duramax 3.0L, and the difference is instantly noticeable. Right off the bat, the quality of this intake is top-tier—solid construction, smooth airflow design, and a perfect OEM fit that required no modifications.

Performance Gains You Can Feel
The biggest improvement is in throttle response and turbo spool-up time. Before the install, there was a slight hesitation under acceleration, but now the power delivery is much smoother and more immediate. The engine feels like it’s breathing better, and I can hear the turbo a bit more, which is always a plus!

MPG & EGT Improvements
I also noticed a slight increase in fuel efficiency, especially on the highway. While gains vary, I’m seeing about 1-2 MPG better in daily driving. Additionally, EGT (exhaust gas temperatures) dropped slightly, which is a great sign of improved airflow and efficiency.

Install Was a Breeze
Installation was super easy—took me around an hour with basic hand tools. PPE designed this intake tube to fit perfectly with the stock airbox, making it a quick and worthwhile upgrade without any check engine lights or tuning required.

Final Verdict
If you’re looking for a simple, effective upgrade for your Duramax 3.0L, the PPE Zilla Intake Tube is a must-have. Better throttle response, smoother acceleration, potential MPG gains, and a cleaner engine bay—it checks all the boxes. Highly recommended!

Easy to install fit great.

I installed this after I had already installed both the PPE Intercooler and Stillen Cold Air Intake. The truck ran good with out it, but man it was unleashed after I installed the Zilla. Totally different truck now. I tow with my truck and this helped my EGTs and how quickly they recovered after a hard climb(Raton & IKE passes). My only regret is that I kind of wish I'd got the Forged instead of Twill AND I should have ordered it sooner. GREAT PART!

I have had it on for 40,000kms. Northern Canada from +30C to minus 40C. It’s great. Low end I notice it has a lot less lag. I recently put the stock one back for warranty and could tell.
I believe it’s quieter as well. It doesn’t sound like the turbos sucking through a straw anymore on acceleration.

Bought and installed this after putting on the ppe intercooler. Actually thought I might get better fuel economy. Just finished a 1200 mile highway trip after installing. It smokes the road and actually jerks the 3.0L to into a new life at certain points in the power band. I also get a very interesting new growl at certain times in the low end. It’s ****’n in a Jekyll and Hyde kinda way.

The part is packaged very well, looks good, and is very light! It took twice as long to remove the stock tube than to unpackage and install the new one. I found that the stock coupler tube to turbo was actually lose from the factory. Check those!

Great product, easy to install and noticeable difference in low in torque. Buy it!!!!

Would highly recommend this part to anyone looking to upgrade air flow and throttle response. I paired this with the hot & cold side deletes as well as the additional hoses. Dope upgrade and much more reliable than stock options.

Can’t wait to complete the air intake system with the air filter cover!

The zilla intake was easy to install and the truck seems more snappy. Noticed I don’t need as much pedal to maintain highway speed. Noticed regrets so far

We installed this and a few other parts from PPE on Saturday. The installation was easy. It fit perfect and looks great. The engine runs better than before with more power. Thank you, PPE

Install went a lot easier than expected. Great upgrade over the stock intake tube. Noticeable tone difference and some throttle response.

Instructions were great, install was easy. The quality is awesome. I still have OEM airbox and filter and still got a nice sound from it. I paired this with the PPE catch can and after installing both I picked up marginal improvement on fuel economy and my regens have started stretching longer. Great products!

Quality product to replace the OEM restrictive intake. It’s night and day difference. Although most people are looking for HP or torque improve, most of these modifications are designed for efficiency and reliability to your vehicle. You will notice a difference in sound quality versus OEM; you get that whirling noise from the turbo which is non existing with stock OEM. There is a noticeable difference in throttle sensitivity. Overall install is straightforward. It does take a little bit of work to align rubber grommet with bolt near firewall. Install time was 2 hours.

Instructions were very easy to read and follow. Install took a little longer than normal. I wanted to make sure everything was correctly installed. Noticed a big difference in throttle response, torque, and the way the engine was able to breath better. I recommend the stock air box with a K&N filter. No more turbo lag is a huge plus! Nothing worst than pulling onto a highway where the speed is 55 and your truck is driving like a grandma to get up to speed. With this you are watching the speedometer start moving quickly. Grandma has left the building.
