I currently own a 2021 Trail Boss wit a 6.2. I know this is a subjective discussion but looking for opinions on best cold air intake. I had the K&N on my 2011 Silverado with the 5.3. Just looking for other opinions.

S & B is what my last 2 have been..very pleased with their products. They don't make ridiculous/"bogus" HP/TQ claims. They just state their systems have the best air flow

 

Many have the Roto-Fab..heard many good things about them. They probably look the best inside the engine bay.

 

Others are Cold Air Inductions, Volant, K/N

I personally just use the Air Raid MIT with a drop in filter and stock box.

Airaid has a diy kit; mount a hood scoop, straight off the throttle body. Short of that I would say keep the stock one. Short of that I personally would go for the rotofab or afe.

GM Performance.  It's a bit more expensive, but it gets the ECU reflashed, carries a GM warranty, and is California CARB compliant.

You can't get the GM Performance intake on a 2021 unless it was optioned for one from the get-go.

Stupid GM.  Why do they have to ruin the good things?  We, the customers, are quite capable of doing that ourselves.

Which unit in your opinion is the best mix of value & performance?

I'd say OEM unless you intend to drag race your truck.  Then I'd go with the GM Performance CAI.  CAI is mostly just a noise box unless you spend a lot of time at WOT.

Doesnt the new body style have a different intake style than the previous? I know on my Sierra it looks like it comes from the top above the radiator and if memory serves on the 16 Silverado it came from the fender. If thats the case, wouldnt that change the test results from BB? Still good info but wouldnt it be different?

The black bear cold air induction testing was done on the K2 trucks and does prove that CAI work!  I’ve said this as well. You will always have “certain people” who will argue till their black and blue with you, but they are a very reliable performance shop. I found the data very interesting. I wish S&B would have had a unit available for them ti test. They make great products. 
 

The main difference from my 2018 (K2) Sierra was the CAI system was on the passenger side.  My 2019 (T1) High Country the CAI is on the drivers side. And yes their is extra air coming in from the frontal grill area ductwork to the fender area and CAI assembly.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

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

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
