Anybody have this in their truck? I am looking to get a cold air intake and there are just so many. Will all intake systems still keep my warranty intact? does anyone have any suggestions? help!

 

Also after getting a CAI installed, does it need to be tuned? what else needs to be done

I have both GM performance air intake system and cat-back performance exhaust. They were installed during vehicle prep by the dealer and included in the factory warranty. A worthwhile upgrade in my opinion. :)

GM intake does not void the warranty as it is a GM product.  GM CAI does have a flash/tune.  Not sure what it does.

 

Other brands could void warranty if dealership and/or GM can prove that the aftermarket CAI caused your problem.

I bought both the both the performance CAI and exhaust about a month ago on GM accessories.

There is up to a 20% discount and, free shipping to the dealer, they installed both for about $180.00 -including the required CAI factory flash -I was all in for about $2,200.00.

The combination adds about 15 HP. IMO the exhaust sound much better, unless you like it real loud.

The CAI cleans up under the hood nice!

The bonus is that it can't impact the warranty and the dealer adds it to the listed "dealer installed" options for your VIN number -so you'd get some option credit on resale.

I am trying to find an upgraded intake tube. One that doesnt have all the resonator chambers and will go right onto the stock intake box and fit the stock passanger side ccv tube.

If anyone has info I would sure appreciate a link.

 

Thanks,

Has anyone heard of having trans issues after installing a CAI? I have a 2014 Sierra with the 6.2 and have had a couple mechanics say they heard of people having issues after the CAI install due to the mass air flow sensor controlling line pressure for the trans... Anyone experienced or heard of this?

When i built my truck online, i picked the optional CAI and performance cat back exhaust. The option codes are on my build sheet are:  5W7 - PERFORMANCE AIR INTAKE SYSTEM (LPO-DEALER INSTALLED) and WBC - CAT-BACK PERFORMANCE EXHAUST (LPO-DEALER INSTALLED)  and another line shows: PDM - PERFORMANCE UPGRADE PACKAGE * CAT-BACK PERFORMANCE EXHAUST SYSTEM * PERFORMANCE AIR INTAKE SYSTEM (LPO-DEALER INSTALLED) 

As it says, the dealer installs it and is supposed to calibrate the ECM. Turns out that the dealer i purchased from (out of town) forgot to re-flash the computer,. After a few months of driving, I was getting check engine lights and it was idling rough. Took it to a local dealer who said I needed a new O2 sensor according to the code. They changed one then got the engine light again. They finally figured it out by contacting GM Corporate who verified that the dealer i purchased from forgot to do it. Local dealer did the ECM calibration and also adjusted the  fuel banks. The first pic is the service order when they thought it was just the O2 sensor. The second pic was the fix. My suggestion is to order and have it installed at the dealer and they can do the re-flash and you will not have to worry about having your warranty possibly voided.

Trying to get a OEM cold air intake for my 2021 5.3L Sierra 1500.  They can't pull anything up by my VIN yet - got the truck in April and it does not have the engine cylinder shutoff chip, which I am ok with. Wish I could find a dealer that knows if the 2020 cold air intake is identical to 2021. The 2019 and the 2020 are different part numbers even though I think they are the same engines. So scared to buy it as it is a special order $ up front, even when they install it and do the required change in tune.

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

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.
