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.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
