6.2 Cold Air Intake

[CounterMeasure]

Watch your k&n's and any other filters for passing fine dust. Most oiled air filters do and my impact warranty. Seeing as most people here are concerned about oil in the intake, I'd bring this up too. I've seen some nasty intake tubes with even properly oiled air filters. The worst being dusted turbos in duramaxes

 

From personal experience, I completely agree. On a previous vehicle, I had a K&N filter that was good about passing fine dust. Wider mesh gives better air flow. It caused the MAF to flip out twice, which would go away if I cleaned it off. After the second time, I noticed the intake was rather dirty as well. Wiped everything down and went back to a boring quality paper filter, and the MAF problem next came up again. Haven't used one since, as possible power increase isn't worth the more likely dust-related issues. Each to their own though.

From personal experience, I like dry synthetic filters more. When AEM first came out with theirs, it seemed great, no dust. Put a round one on my old '01 5.3 that was grey. But I bought an AEM square direct fit for my Duramax a year ago, and they had dyed it red (even had red blotches around the sides to look like a K&N) and that one passed a small amount of dirt. So I dunno if you can figure out the filter micron ratings but definitely do so.

I'm still looking and can't decide oiled filter or dry I have a Dry AFM in there now, but I want more HP. Have exhaust, chip and tune. Now just need CIA and gears...

I have a dry synthetic filter full Airaid Kit. It sounds awesome at full throttle and you can definitely feel the power increase and better throttle response.

Anybody run the Volant CAI set up
