Anyone have any experience or thoughts about the K&N 63-3109? I would like to add a CAI, and even though I don't expect much of a HP gain with any setup, I want to get a good option. I like the Roto-Fab but the K&N can be had for $150 less. The snap on lid of the K&N with the rubber grommets is questionable to me for some reason. If anyone can give feedback it would be appreciated.

Not with this one specifically, but I have used KN in the past on my 2500HD w 6.0L V8 and was very pleased with it.  One thing in particular, the K&N publishes the HP Gains from Dyno Tests.  It looks like the results for the 5.3L V8 are 15.7HP gain and that is outstanding IMHO.   The pictures I saw of the KN setup for the K&N 63-3109  have a nice factory finish under the hood, and the clip on top is using rubber grommets with oversized pins that pop into the holes, that would be a very tight seal, thinking about getting one myself now - where did you find it for $150?  I'd snatch one up quick at that price, but that sounds too good to be true.

It's $150 less than Roto Fab. Found it for $335 on ebay. I had a K&N years ago on a 2002 Silverado and it served me well without issues. I seem to remember reading on here from someone that they suspected the K&N would require tuning where the Roto Fab does not. And I do believe the Dyno sheet they advertise is for the 6.2

Just don't overoil the filter when you clean it and the K&N will serve you BEAUTIFULLY!!

I put one on my truck this weekend, and have 400 miles on it since install. I have averaged 19 mpg, which has been mostly highway, per the vehicles info system (which I know can be off at times). The sound is great when you put your foot in to it. I have had other brands of CAI's, but I keep coming back to K&N. Install took about 30-45 minutes, and it does seem more responsive. The rubber grommets hold the lid pretty tight. I didn't feel uncomfortable with it. I have a 19 Denali with the 6.2L. Hope this helps.

Has anyone had any computer issues with the 63-3109 K&N Kit.  I installed one on my 2019 Sierra Denali 6.2 last night (with disconnected battery), took it for a test drive with no problems.  Sounded great, all seemed good and ran it for about 20 miles, averaging 55 MPH.  This morning, I ran about a mile down the road, about a mile at about 35 MPH, to a garage to wash it.  I washed it, pulled it out and parked it.  1/2 hour later, I went to start it, and it just turned over.  I tried 3X, but no luck.  I disconnected the battery for 20 minutes, and that reset the computer and I got it started.  Nothing in the instructions about getting it tuned, or retuned or anything.  I bought it for the increased HP and hopefully increased mileage.  I tow a motorcycle trailer, and I'm hoping this will help.  Any thoughts?

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
