I know GM has a CAI system for the 6.2L but has anyone come across any aftermarkets yet?

None that I could find.  But maybe I'm not looking in the right places....

 

It's pretty annoying actually.  I really want to install one on my truck, as I have the cat-back system on my 6.2, and the intake would finish it off nicely.

I would imagine it is only a matter of time.  Why it is taking longer for this model year, not sure.

 

I got the GM CAI on sale back in Nov for $426.  A little pricey compared to CAI of older models.

T1XX Generation GM changed placement of air intake from passenger fender to driver fender. Guessing this is why aftermarket CAI is taking longer.

 

The 2007.5 - 2013 GMT900 and 2014 - 2018 K2XX had nearly identical air intake location so aftermarket was able to release options ASAP.

Plus, from the GMT800's up to 2018's the air filter it's self was the same.

Good ol GM.

 

If it ain't necessary, don't change it for 20 years. 1999 - 2019.

It is nice.  I keep one air filter on hand for when either my 2002 Silverado needs one or our 2016 Suburban.

It doesn't take a rocket scientist to design an intake with AutoCAD....

There must be another reason besides the location...

Maybe it is the fact that if you increase air volume the truck will not run properly until you tune for the new intake.  Since the ECM is still locked down then new aftermarket intakes will not be available until these new trucks can be tuned.  Just a thought.  Since the GM intake comes with an update to the ECM to show a different intake is installed is the reason I'm pointing it out. 

 

I guess a way to tell is install the GM intake and don't get the update and see what happens.    I was planing on taking my truck to a dyno and getting the results all stock, then install the intake and see what if any changes occur and then have the dealer install the update and dyno again to see what happens.

Makes sense.

I don't see the GM intake as a TRUE CAI, though...So it would be nice to get something soon.

The GM “cold air” intake sucks air out of the same small hole on the radiator shroud as the stock intake, so it’s more of a loud air intake than anything else.  I could be wrong  but I’d bet the ecm reprogram with the new intake may have more to do with the way the new intake directs air over the mass air flow sensor.  The stock ecm can adjust for more air flow (but since this intake still sucks air out of the same small hole in front of radiator, I doubt it’s necessary) but how the air flows over the maf sensor can sometimes be an issue. 

 

I could see see a delay in an actual intake that flows more caused by the stock air inlet design and location.  A new radiator shroud or portion of it may be necessary for any actual gains, or a totally different location of the air inlet.

The new PCM mapping only accounts for the noisy/sound waves the air coming over the MAF sensor that the new  intake produces.   It reduces the compliance .002% on 2 tables. That is all.

As with most intakes,GM's intake is nothing more than a noise generator. Zero gains in performance and MPG.

I take it you are a tuner and have this info from GM?  Not doubting you, I just like to know sources is all.  Kind of like when you right a book report and have to site references.

Downloaded my stock  "tune" as soon as the truck arrived at my house.

After  spending 200+ hours dyno tuning last year, it's not rocket science.

 

Any tuner can download and see the changes, there are no secrets or hidden scripts.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.
