Looking to purchase a CAI

[BigRed76]

I have an 08' Denali and wanted to know what is the best intake out there for it. Also .... does anyone have (or can someone please shoot) a short video of what the intake sounds like when you turn off the car with the hood open? I remember years ago installing a CAI and when I turned off the car you heard a hiss that I was told was the air rushing out (not sure if I was being fed $hit or if that was true) but want to hear an actual intake LIVE .... thanks in advance!

Some of them do make a nosie at shut down (K&N) or similar. You should look into AEM Brute ForceDry Flow filter, it does not make any sound on shut down. It is a great CAI and made the most power on the dyno when compared to the K&N, Fram, Outlaw, GMPP CAI. Good luck!

Not sure what sound you are talking about at shut down? I have had the best in both Volant and K&N and never heard anything at shut down. Both intakes are great, highly recommend either of the two. AEM is also a good product, I have never ran one in a truck, but I have in other cars that I have owned. To be honest, I dont think there is any real HP differences between the "GOOD" CAI's. Just get one with an enclosed air filter box, otherwise you suck in to much hot air which defeats the purpose of a CAI

Not quite so. We dyno tested several CAI and there are power differences between them. Also the whole "eclosed" air box deal is not true. My IAT are 5* above ambient temps and its open element filter.

Interesting. I think I would have to see it to completely believe that.

What is it that you need to see? If you want to see the dyno graphs and all the logged data go on silveradoss.com and under the bolt on section it is a sticky there about it titled CAI WARs.

i started with the airaid tube and a k/n drop in filter. it made the engine louder. i just installed an afe stage 1 kit..its pretty much a closed box with cone filter..now my truck seems more quiet..i am pleased..no hissing but i know what you are talking about, my 95 yukon did that. if you get something enclosed you shouldnt hear much

I am happy with my Vararam intake...I wrote a review when i installed it...

It goes back to a LONG discussion on closed box intakes vs. open filters. IMO more air flow through an open filter is better than channeled closed off air flow because it restricts the amount of air

With that said, I replaced my stock paper filter with a K&N drop in filter. Only reason I didn't go with an open filter is they get dirty fast!!! Plus I get more power from my tune than I would ever get from an open filter and these trucks won't ever see the power levels that you really need an open filter for

Art was helping at the dyno for the results I posted in my intake thread.
