Q: What is that intake divider that looks like somthjing for a Hoover vacuum? Should I leave it or remove.....Seems like it takes up a lot of room in the intake tube...

Uhhh, does it have any wires connected to it ?? If so, that is probably the grid heater used on cold starts . . . maybe post a pic ?

It siys directly behind the air filter right before the turbo in the air box tracked....

Dude, that's a Factory cold air intake that pulls air in from outside the fender where there is cooler air................you want to remove that immediately and put a "hot air intake" like this pronto! lol

Bonus points, +5mpg and +50hp if you can find one that is situated directly over the exhaust manifold and turbo. lol Double bonus points if you add the 50hp and another 5mpg straight exhaust.

That is probably a "muffler" to reduce intake noise.

Soooo, you guys are a bunch of smart a$$'s I see.......lol

Well, I have been putting Cold Air intakes on these for a while, and never seen a 4 way divider in the intake tube before. I also usually get rid of the silencer ring right in front of the impeller. So I am curious what mods everyone does to these....Figured just leaving that part out alone would double the air flow...

If I'm thinking of the part you are referring to it's the round filter portion that's mounted in the middle of the duct. Has a foam filter and stiffening ribs. Likely there as to not let the duct get sucked closed.

The fellow that said “muffler” would be correct, about the only thing you’ll notice is a little more noise. Was akin to flipping your air cleaner lid over from days past. Where did you end up getting your truck from? Jim

Got it in Ohio....They are getting snapped up really quick in my price range.
