GM Performance Intake on 2021 6.2

[AllTerrain13]

Has anyone installed a GM Performance intake on a 2021 6.2?  The parts listing 84854457 states Unlike 2020 and earlier versions, these intakes are currently unavailable for installation on vehicles that did not have the performance intake ordered from the factory. They receive the calibration for the intake while on the assembly line and this cannot currently be programmed by a dealer service department.

 

I am curious if turning off the filter minder and disconnecting the battery for 3hrs similar to the S&B would be the ticket?

I have the GM Performance intake on my 2020 5.3L.  The ECM update that comes as part of the intake accounts for the repositioned MAF sensor and the altered airflow dynamics.  Turning off the filter minder, which you're suppose to do anyway when installing this intake, and disconnecting the battery will not mimic what the update is intended to do.  There are several threads on this site that talk about this modification.  I recommend reading the first post by Zane on this sub-forum as he talks about his install of both the performance intake and exhaust.  There's also an informative article on TruckTrends.com about the intake.  Bottom-line - for GM's performance intake you need the ECM update, otherwise you will not get the full benefit of the intake, and may encounter some other challenges such as the CEL lighting up and decreased mpg as has been reported by others.  Finally, while the intake itself probably only adds a horsepower or two, which is negligible for such a heavy vehicle, I noticed some additional pep in my truck, which I attribute more to the ECM update/tune rather than to the increased airflow provided by the larger surface area of the performance intake filter.  Yes, the seat-of-my-pants is calibrated...

Thanks,  I saw the post by "Zane" and it does not mention 2021 MY.  My specific question is regarding 2021 and if anyone has installed it.

I do not believe the GM Performance intake is any different from 2019 to 2021 model years in terms of hardware, however, what is different is how GM has changed their availability.  If I wanted to add it now on my 2020 it would be too late as it's no longer available as an accessory, for whatever reason.  Maybe too many people were buying it, then not having it installed by the dealer, and then not having the update performed if they chose to install it themselves, and it was causing headaches for the dealerships to correct, but I'm just guessing.

Would this be the same for any brand CAI?? I have a 2021 6.2 litre with the "rotofab CAI".....excellent quality. Will this throw codes or need a "update performed"??

Rotofab said no, but anyone have first hand experience??

 

Allterain13....you might want to check out the Rotofab CAI......they make one for a 5.3 litre and 6.2 litre for 2021 gmc, chevy......excellent quality and  they told me they built it to gm specs.  I haven't thrown any codes yet, its been on for one month. I did what the instructions said and disconnected negative battery terminal while installing and left it off for 2 hours.

I have had a Rotofab CAI on for about 2 weeks and no issues with throwing codes or decreased mileage. Had one for about 18 months on my 19 Denali I traded off without issues either. They make a quality product.

The big difference with the GM CAI is they were going after CARB certification for compliance and haven't gotten it yet for their 2021 models. You can order a new one with the GM CAI included and its fine so this is only an issue for adding on later, at least for now. This is also why it is available for 2019 and 2020 as they did get the CARB cert for those years. 

 

Just about any plug and play CAI will work just fine but you will notice a call out now on almost any site/brand that says not CARB compliant where a state requires it. In CA, smog is only needed after 6 years on a new vehicle and I'd bet half don't keep their trucks that long anyway nor have I heard or seen anyone ever complain about failing smog for a CAI being installed.
