I've heard to stay away from k&n because they let too much trash through. You might want to look at AFE or Bills custom intakes also

ok so just how useless is the factory airbox's on this lly truck.

right now im planning on just a hypertech not much more, gutting the factory exhaust, and yes installing a afe mouthpiece found it for under 200.
I would like a whole intake setup, but me fixing to drop about 220 on a tranny flush from amsoil, dont want to drp another 200 plus for a whole intake.

Ok so i picked out two air filters i like I have ran a oil filter on my dads duramax with no problems, so here are the two. 1 s-b can get new for liek 35.00 bucks plus shipping looks like jsut any other drop in air filter useing the retaining the factory lid.
2. Or going with a afe drop in filter its about 70 bucks but you dont use the factory lid.
it looks like this.



If anybody has any better ideas im open to listen, or some used parts for my truck

If you're just going to keep the stock intake, keep the lid for sure. If you do a little work and isolate it from the hot engine compartment air you'll have a good functioning intake. Stock they pull most of the air from inside the engine compartment which is horrible. A true cai along with an afe mouthpiece will make a good difference.

If you're still looking for exhaust let me know.

I've seen guys put foam insulation around the top to seal it off, also there's a spot where you can cut out a hole to pull in outside air. There's a DIY by hook'em horns that shows it all pretty well.

No worries. I'm a vendor and I helped you save money rather than pushing a sale lol. So hopefully down the road you'll look me up when its time for that exhaust ;)
