Your stock one. It flows MORE than enough.

Do you have any mods to support an intake manifold swap, what are your current mods? An LS1 manifold is going to flow less than the truck one, hell the LS6 intake shows virtually no gains. Dont waste your money.

I don't have any mods done. I've only had the truck for a couple of months. I was asking more for informational purposes than anything else, that way should I want to get one down the road I would know which brands to look into.
Down the road should be after

  • Custom Tune
  • Muffler
  • CAI
  • Long Tubes
  • Gears/Truetrac
  • Vette Servo and Transgo HD-2
  • Efans Denepding on the year
  • Cam/Converter

    Etc, etc, etc, etc.

Your truck intake flows just fine :imo

Yeah, I think I'd stick with the truck intake for your low-end's sake.

Expensive, and rather pointless unless you've got some other heavy hitter mods. Or well, you could just replace your intake manifold with a blower, haha.


I'm actually a little curious how much of a difference a lightly ported/polished OE TB makes (I've got one, but installed at the same time as CAI & exhaust so I couldn't tell specifically), versus a BBK 80mm, or a BBK 85mm, etc., etc.? just slightly off topic here.

Ah...gotcha. I don't know a whole hell of a lot about these trucks or their different specs. I've always been into S-Series trucks, this is my first Silverado. I had to pick it up due to needing more room and functionability.
