2002 3500 Cold Air Intake, Cheap And It Works
 

Bought a used box, modified it with a 4" alu pipe conection, piped it to front. In front have a trimmed 4 x 8 funnel, so it fits next to intercooler.
Batteries is side box under bed
will see if i can up the rest of the pic's

here are the rest.

ok first question why? you turbo does all the sucking of air if you start to force it it it will become turbulent and will eventually result in a loss of fuel milage, it happened on my budies truck, basically it will be working against itself. the tubine pulls in air then with that that will be forcing air against the turbine blades causing them to intern slow down

some dyno results ive seen beg to differ

i can see what 94cummins is taking about..

on a dyno your not forcing the air in. your just giving the intake easy access to fresher/cooler air.

also all the tubing is corrugated it's a bit restrictive... probably no enough to make any substantial difference

I been toying with the idea of moving the batteries to the tool box in the bed to make more workin room under the hood and moving the air intake up to the front of the truck so the air comes in right off the front of the truck and is basically a straight shot into the turbo area.

Look at the some of the drag racers and pullers, they take the headlight out and stick the filter up there to helping forceing air up there cant be all bad.

they have way larger turbos taking in way more air the out little hx35's hy35 h1c's etc..
alot of those rig are race only.

I'm talking about the Duramax trucks. I know allot around here that run like that on stock chargers.

i bought one of these thought i would mount it over the top of the intake.
