Is anyone else in here waiting for PPE to release their Carbon Fiber intake tube for the 3.0 duramax? They should be released in 15-30 days from now and are estimated to retail for $390-$450.

Still waiting… they got a small supply of pre-release stock and will be restocked early November to early December with first full order from manufacturing facility. They sold out very quickly, I paid but their website had an error still selling when out-of-stock - got a phone call, this is what they told me anyway.

I end up going with a cft intake pipe. I didn’t want to wait plus the cft is a lot cheaper in cost for a product that’s not really going to be seen by many.

Did you go with the twill carbon weave or the forge carbon?

Curious if you notice any difference which I’m sure there will be (response/sound). I had a K&N but found out the filter was letting all kinds of junk past so took that off, waiting on this guy now.

Me too…hoping to see any reviews from you guys that got them. Is it worth the expense. Let us know.
Installed mine today along with a few other things - it was NOT an easy task. Took me about 3 hours overall.
I waited to do several things at once:
The PPE Forged Carbon Intake is a NICE PEICE of hardware. Very well made and looks great.
Since I was replacing the whole intake side basically - I removed a lot of things (filter box, Intake duct, coolant tanks and a few other bits) just to get to the point of removing the factory intake tube. Once all those things were out of the way, it took me quite a while to get the factory intake tube out. It is such a tight space, and I took my time.
Once I got things out - putting the new parts back in wasn't as hard. The long intake tube took a bit of fenagling to get into place, but once there, it fit great. The biggest downside is that it is buried behind the engine, and you cant really see it once installed.
The resonator delete is quite a nice piece as well. It did take a bit of force to get onto the turbo, but once seated, it fit nice. I am glad I also replaced the soft factory tubes with he PPE silicone tubes, they are stiff and hard to install, but should be worth the slight extra effort and cost.
The K&N intake was also a bit of struggle to get everything to line-up, but once it was aligned, looks nice.
Final install of the engine cover, covers most of the hard work. Doesn't bother me too much, as I am not going for looks, as much as some performance increase.
Overall I removed a lot of GMC plastic parts for much higher quality.
First drive impressions:
I can't say for sure which element provided the most bang for the buck, since I did it all at once though. Right now, I would for sure do it all again and am happy with the results so far.

First drive impressions:
- You can ACTUALLY hear the turbo - and it sounds awesome!
- My truck finally sounds like a diesel truck. Not a ninja diesel like it sounded like from the factory. It's not as 'loud' as a full 6.6L, but it sounds so much better
- Butt dyno definitely feels some improvement - I had to turn down my pedal monster setting because I was breaking the tires loose too easily. I would say more low end torque improvement then anything.

Excellent write up! I’ll have the same setup once my PPE intake pipe comes in hopefully before the new year

Really good write up and glad to hear it was beneficial. Will probably do the same.

Really interested to see if the increased performance is actual and not just the guise of better sound! Keep us updated

Appreciate the write up!
Just installed my PPE pipe. All other air intake components are factory. Not much of an increase in turbo noise but a single “drone” sound when letting off the pedal. I do notice an improvement on throttle response.
Planning to install the Stillen air scoop then deciding between the K&N air box or S&B.
Thoughts on your decision to go with the K&N?
I did have a minor issue with my install. After a couple days of driving I did get a CEL. Checked the code and it was for lean condition due to an air leak. After checking all the new hose clamps, one was slightly loose. I retightened all of them and have not had an issue since.
Engine still sounds great. There is a slightly noticeable torque gain. Best part so far is I've gain almost 3mpg. Now averaging about 28mpg for my mixed commute. I'll keep an eye on it though - only been a little over a week. I have been heavier on the throttle too just testing things out.
I am still very happy with the setup and would recommend it. If you do install all the intake hoses from PPE - make sure the clamps are very tight. That turbo sucks a lot of air.
