Is this an esky? Is that the generic mishi cooler in.. Looks like 20" ? Just drain the Trans fluid, plumb that bad boy in and refill? How's it shift, afterwards? Any notable differences?

What does that poly mount do?
I get the point of studs - I did them on pretty much everything on my last build, but, do these have an issue with headers sealing, that the studs are kind of a preventative measure?


And it's all small stuff!
17 Tahoe

It’s the Mishimoto for the Silverado/Sierra. What’s the same on ours.

Like Wes mentioned, you don’t need to drain anything just add a little bit for the extra fluid you need due to the new cooler.

No noticeable difference

The new motor mounts are because there are practically zero aftermarket options and none of them last, not even the factory ones. These new mounts will probably outlast the truck itself.

The studs just make it easier to remove the headers. I used to have a small leak, but that was mainly because of the crappy gasket I had. Always go OEM.

Attempted to install my JL AOS, today.

I have questions :

Low and High side are marked blue and red, respectively. I understand in the AOS the side with the steel wool insert is supposed to be the inlet, right? (blue) And the red side is the one that goes into the manifold, just behind the TB. My L86 doesn't seem to match their install video, so, there's that.

Hoses are a bit long and as a result, there's a kink in the TB inlet hose, not sure how to fix that. I don't think that's possible, given how it's sent.

Am I doing this right? Main reason I ask is that, although I've never had the hood open on a cold start, I did see what initially looked like spray coming from the driver's side valve cover, just below the AOS, and was a concerning amount smoke. Maybe it was just heating up, or maybe there was a problem. Somebody put my mind at ease.


Just in case, I set it back to stock so I can run around and not worry about it and I'll wait for one of you to give me a confidence boost and I'll try, again, tomorrow morning, lol.

This is what I was looking for! Guess I'll have to order the extended version? Or is it even needed?

This picture confirms how I installed mine - did this ultimately work out? Anything you'd change?

What are you guys using to even out the bed when all seats are folded down to make a flat surface. Was looking for some type of roll out bedliner without success.

since getting the injectors replaced in the wifes 2016 she has reported it still having random hesitation primarily when accelerating from a stop or near stop, like slowing down and then accelerating again. no cel or anything but I did find a stored code for a knock sensor p0324-00, so ordered 2 new knock sensors and I already have new 02 sensors sitting here for it, so when those arrive I will do the 02's and knock sensors and see if anything changes

I just pulled it out put a Lloyd carpeted mat back there and called it good. Hated the slope, wife hated it more. We (her) rarely put the seats down in third row but if we fo theres a good 4-5” ‘step’ but better than havin ***** roll out on her. i open the glass first to make sure nothing is gonna fall out anyway, buts shes a shorty so doesn’t really work for her

Made a 450 mile drive in the 2019 today, I74 to I77 toll, two of us and good sized luggage load. Kept telling myself to drive conservative but still saw a lot of 80+mph. With the AFM active I got 22.3 mpg by the readout, I'll do the math tomorrow but it's usually real close. Good machine.

Got a noisy tire and can feel it, OE Goodyears with 34k miles. Looking for quality replacements now.
