I am not a person to throw money away so I have been doing my research on which CAI system to install on my 2020 Silverado RST (5.3) or if I should put one on at all.  My Flowmaster Flow FX kit should be going on today. What I have read and watched on all the Youtube videos is that the manufacturers of ALL brands make claims that they work to increase HP/TQ and MPG. There are some videos of dyno tests that showed great and not so great results. Also some folks have done real world testing themselves and came up with vastly varying results. One guy shows he ran an intake temp sensor for 3K miles before and after which proved the intake air temps changed vary little and only improved his MPG by about 1. Some have even said their MPG were reduced after installing the system. I am looking for NO BS real-world experiences which include the type system, please limit responses to 5.3L motors and not the 6.0L (Don't want Apples to Oranges comparisons).  Thanks In Advance!!

Wow both guys that have modified their trucks for their own taste are chastising people for doing the same. I’ve had several factory hot rods of late that had factory aftermarket looking CALs on them.

This is going to be a very subjective decision that you'll have to make considering what things you value most in a CAI... 

  • Do you want HP gains? 
  • Do you just want to open the engine up and see some nice sound improvement, plus some small MPG gains? 
  • Do you want something that looks good under the hood? 
  • How important is having a GM part under the hood, to avoid any possible drama if you have an engine issue under warranty? 
  • How important is cost? 
  • How important is ease of installation? 

With all this in mind, I'll give you my (subjective) 3 best options: 

  1. GM Performance's CAI. I installed this on my 5.3L because I wanted an OEM part, and the ease of installation was the best (since it's built by GM for a GM vehicle.) They only claim about a 2hp increase on it, which really didn't matter that much to me. Plus, I like the way it looks under the hood. Lastly, I was able to get it for around $470, which is pretty average for some of the CAI systems out there. 
  2. Rotofab's CAI - similarly easy install, has some documented dyno improvements over the GM CAI. A lot of guys on here run this and are really happy with it. 
  3. S&B CAI - hard to get right now. It's backordered. But they have the best dyno claims out there. 

Good luck!

Anyone have any experience with the Cold Air Inductions intake? Looks similar to the Rotofab, but uses the factory lower box. Considerably cheaper, but looks to be well built.

You will have some grumpy old individuals on here who will say it’s a waste of money but there are tons of research and proven data that states otherwise. I have an S&B on mine because they claim the most air flow and least restrictive out of all of them. Plus for $350 it was a great price. I like the RotoFab or GMs cold intake also. The cold air inductions intake and Corsa both use the bottom of the stock box. 
Ive noticed better throttle response with mine and have picked up a few tenths of sec with it and exhaust on my truck. Those are my facts.  Good luck with your decision.

What if we're a grumpy, younger individual?

 

A CAI might add a bit of horsepower (a few) as you approach redline.  How often are you up there?  You're not going to see any appreciable increase in MPG.  Considering how much money and effort auto manufacturers are putting in to eke out a bit more MPG (auto start/stop, air dams, active grill shutters, etc.,) you can rest assured that if a few cents per vehicle improved MPG, they'd come that way from the factory.

 

Your truck has two valves per cylinder.  That's your air flow restriction, and no CAI is going to fix that.  But sometimes a placebo is worth its weight in gold...

The amount of BS lies that are in these forums on CAI is absolutely ridiculous and complete waste of money. There’s no bolt on that will guarantee such gains that a $400 tune couldn’t do much better. The computer is controlling everything.

Here’s a forum discussing what’s already been proven over and over again. People with vast experiences and have yet to be proven wrong especially by newbies and wannabes that have ZERO Dyno testing other than their butts.

May as well put a CAI sticker on your car, it’ll give you the promised mindful horsepower without a tune!

Here ya go, here’s just one of the reasons why you should consider spending your money somewhere it would apply itself in a much more positive way. Just one of the many lawsuits consumers have filed throughout the years.

 

Don’t be taken by marketing firms paid big money to find your inner automotive desires, Research it before you buy it.

I put an Airaid Jr on my truck (intake tube and filter only). I had zero expectation of any hp/tq gain. I did it for 2 reasons. 1 it sounds better and 2 I don't like the massive air chambers on the stock intake that are just there to quiet the intake noise.

It's also a 10 min job to go back to stock for any dealer work (don't need to give them any reason to deny warrantee work).

See I told ya they'd come out!! Hook, line, and sinker..

 

Here is a dyno video just for proof! They do make a difference.  Here is just one of many FACTS that prove they work. 

 

 

Here is another Dyno showing 5HP to the wheels!

Any HP gain to the new T1's is a win for us owners. YOU CAN"T TUNE them for $400! By adding a CAI and an exhaust is a way to free up HP and gain performance.  Heck hacking off the flappers ALONE free's up HP because they block 50% of the stock exhaust system. It's terrible.

      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.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
