I just installed the GM Cold Air Kit on my 2019 Silverado 6.2L. I had the chance to buy and compare both the K&N 63-3109 and the GM Part #  84789804. The price difference was about $85 more for th

Yeah I have mixed feeling about an intake.  After reading the thread by Rotofab and seeing all the opinions tossed back and forth.   For the price you're going to pay for an intake vs. the end hp/tq g

K&n has their 2019 Silverado intake up for pre order on their site. A rep told me they should ship out soon since production has started.

The answer is No.

2019 T1 Gm trucks have a completely new air intake setup that comes thru the top of the grille and to the drivers side for intake.

The intake picture you posted is for the previous gen K2.

To the OP, unless you live in central America, there is plenty of cold air to go around right now, I belong to other forums and the most popular topic is where is my block heater plug, lol. With a new p/u with a new intake system, I would bide my time, let someone else be the guinea pig to see if a CAI is worth it on this new generation.

Yeah, I found that one, but with only 13% more airflow, its not worth the cost, considering the K&N for previous year is only $280.  I will wait for K&N or AFE to produce something.  At least I hope they will!

That’s great news, good find!  Now I’m curious if we have to tune the engine after installation?  I know some others said that might be necessary.. but i didn’t see that in the instructions.

I was one of those checking every other day on their site to see when it would be available lol and that I know of you don’t have to tune it the computer will eventually adapt to the extra airflow and change what needs to be changed. The GM intake comes with the “tune” so the computer won’t have to do it itself. (Don’t quote me on this information it’s just something I got told)

On the 6.2 per the webpage above, it says it increases 17% airflow, I wouldn't imagine that there is that much adjustability in the ECU perimeters for that difference. Which is why they have a calibration for the intake.

It's a bit expensive for plastic and a rubber hose connected to the throttle body...

New Era Performance released theirs.  Expensive at $400+, but 16hp/21tq on the 5.3 seems fairly good.  

 

Im was gonna wait and see what else came out but the plan is to dyno before and after the intake for my 6.2

K&N saying theirs makes 15.7hp/32.5tq on the 6.2

I wonder what this fine print means:

 

“Horsepower gains based on similar vehicle dynamometer test. Results will vary.”

 

Those numbers seem pretty sensational and don’t really mesh when you consider the numbers gained from the AT4 off road performance package, which includes both the GM performance exhaust and the GM intake.

 

“Thanks to these additions, the AT4 Off-Road Package delivers 435 horsepower and 469 lb-ft of torque - increases of 15 horsepower and 9 lb-ft of torque over a Sierra equipped with a conventional 6.2L.”

 

The GM exhaust from that truck is listed in the accessories store as being good for +13hp and +8tq by itself. Simple math would then indicate that the GM intake is then only good for +2hp and +1tq. That would explain why GM doesn’t directly publish the gains from the intake apart from a % airflow increase...pretty sad.

 

So, either the GM CAI is terrible, the K&N is really great, or someone is lying???

 

Curious what everyone makes of this because I am definitely in the market. That said, I’m not in love with using a K&N oiled filter and destroying my MAF sensor...

Found the dyno sheet for the K&N. Pretty impressive. Guess I got some thinking to do.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.

      Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin.

      Ahh, sorry about that - I got some bad info. Newdude is correct. That's what I get for working 13 hours straight ... on my "vacation", lol.   Should've checked the files I had instead of the internet.   Anyway ... this is GREAT news, since this would've been an absolute friggin nightmare to get working.   I don't think the lack of VVT is causing this - you've got another issue. Wiring, I'm betting.   I'm telling you right now, your computer isn't bad. If it worked before the swap, it's working now. You need to do some more (better) diagnostics and figure out exactly what you're missing. Did you test every wire directly at the MAF? Have 5V reference? Ground? If you're reading ZERO g/s, your Hz isn't much use - it's going to be the wrong value anyway. The MAF is not working, and you need to find out WHY.   I got this off the net, so VERIFY first: Pin A: Black (BLK) wire, Circuit 552, serves as the Sensor Return (Ground).  Pin B: Tan (TAN) wire, Circuit 472, carries the Intake Air Temperature (IAT) signal.  Pin C: Yellow (YEL) wire, Circuit 492, is the primary MAF Sensor Signal output to the PCM. Pin D: Pink (PNK) wire, Circuit 339 or 539, provides Ignition 1 Voltage (Power).  Pin E: Tan/Black wire, Circuit 552 or similar, often associated with the Intake Air Temperature ground or signal return.  Global-A list: https://postimg.cc/KKJnQC85

      Correct....the end user can't reach to Realtruck directly like they can if they purchase a Bak, Undercover, etc...  It has to go through a dealer.
