Installed a CAI

[ljn21]

Can't say that we say anything huge, but we didn't have the Tahoe that long before I installed it.
With the CAI, the GM performance exhaust a catch can and the Pedal Commander we avg 22.5 mpg on a trip from NC to the NH/VT and back, that's using premium fuel and cruise on most of the way.
I'm not sure what others with the 6.2 are getting?

Not to derail the original topic but how does the GM exhaust do while cruising on the highway when the cylinders turn in/off…any drone?

Zero drone, I love it. Not the loudest exhaust but it sounds much better than stock. I tried just replacing the muffler at first and the drone was unbearable so I installed the GM P.

Very nice set. Well done. I added a CAI to my 6.2 High Country. Looks good and liked how it cleaned up my engine bay as well. Of course that only took me down that road. Gonna have to polish, chrome, and powder coat some other parts to give it the complete look. LOL.. That of course is in addition to the headers.

Sorry about digressing. Your CAI and engine bay look good. Good choice. Well done.

Looks sharp. I am on original air intake but swapped the OEM filter to a K&N washable/reusable for both engine and cabin. Nice thing about the K&N is you can set your own time schedule to remove, wash, dry and reinstall……if you know your not going anywhere for a while….or at least the vehicle isn’t you can remove, wash/rinse and let air dry for a couple of hours then reinstall. I keep the OEM close by just in case I do have to make a emergency errand somewhere. It was a lot easier before with two vehicles, I could just use the spare and let the K&N dry in the sun for a couple of hours.

Pretty happy with our first longer trip from NC to NH/VT, averaged 22.5 MPG with our 6.2L and that was about 2000 miles round trip.

damn, and I was all stoked to see 19.9 average from our 5.3 after about 1000 miles round trip...

Ran them in the dishwasher for years, came out dry and ready to go. Don't use them anymore since we drive off-road a lot, back to paper.

Cold Air inductions, volant, corsa , s and b, .. who has the best intake?

Honestly, none of them. Yes I just dropped that grenade.... Studies show they don't really improve performance. Your stock air box is actually colder and more insulated. Best bet is to do a drop in K&N or AEM filter, or just stay stock.

Is this comment specific to the Yukon platform or are you just making an in general statement? While I would agree an open cold air intake setup might not be the best idea (heat soak), an enclosed solution would be the logical route. Now we all know that a CAI is not going to give you 50+ hp (need stickers for that lol), but they should help the system breathe a bit better. Please share any links you may have to validate your comments. Thanks

A general statement. It’s a misnomer. Most of these aftermarket CAIs actually aren’t “colder” because the insulating material is not as thick as the stock one. Or the box is made of metal. Second an oiled filter is not always better. Where do you think that oil could be going? In your intake. Breathe better? Maybe but unless you are also doing a full exhaust long tube headers and no catalytic converters an aftermarket intake isn’t really doing anything for you. Also by “breathing better” then that means the filter then must be more porous to let more air through, and then also thereby letting more dirt through? There are tons of threads on this topic on forums out there. I don’t have the actual studies in front of me, but many will tell you that they don’t really do much for you other than increase the sucking sound of your engine. If the GM engineers thought you needed a better intake so that your engine didn’t have suck as hard to get air, then wouldn’t they not have designed it? You could argue that the CAI gets better MPG. But does it? More air in = more fuel in does it not? On my last vehicle I got great gas mileage with a tune on a stock engine. After bolt ons and tune my mileage went down, but was still pretty good… just my thought. I think they’re a waste of money unless you’re going to go with full bolt ons.
