Fabricating cold air intake inlet

[CUMMINZ]

I started today to modify my factory clean air intake box to provide cooler air and also to provide additional air.

Now that I have it back together I can fabricate a flexable hose to mount to the bottom of the box that will protrude 20"s straight down toward the bottom of the truck where it will pickup cooler outside air. Air off the hot pavement will be cooler than engine compartment air. Once I get this hose fabricated I will update the post to show contents.

Will the flexible hose intake be located in a known position where it won't suck in water or flying snow?

I'll take it down to within 2-3"s of a piece of fender molding.

That is the same thing as the DPP towing intake on my truck and few other guys are running them also on the 5. 9's. I like mine alot. Seems to keep EGT's very in check while towing at road speed and you still pull air from the fender inlet also. When asking about the chance of it sucking water they said if the hose was dipped into water it would pull air from the next easiest spot, the fender. I have driven in driving rain and have had no troubles, but haven't tackled any snow yet, but I don't see it being a problem. Scotty

The 5" hole I cut in my air box is a perfect match for a piece of 4" corrigated pipe. I cut it 21"s long. Photos show how it fitup. I drilled one small home in bottom of box and top side of pipe and used plastic zip tie then corked (ha) around the top. I cut bottom of pipe to face forward. Is about 3"s above the bottom of the bumper.



I plan to install Cool Blue Hose when my friends at Diesel Power Products get their supply in.

Cool Hose

I am working on the Cool Hose for the 6. 7L. The company that manufactures my other hoses is doing them for me. It is a pain because of that EGR spout on the hose. I have kits very similar to the homemade one above in-stock made by PSM. We put one on a truck last week. I think I am going to take the 6. 7L plunge myself so I'm sure I will be doing lots of experimenting!

Quote from Gale Banks...



Of course, a vehicle?s airbox is where the outside air comes into the engine. Due to cost

restraints, factory airboxes usually allow for a well-engineered aftermarket airbox to do

a much more efficient job at directing the air into the engine. The best-engineered

airboxes are sealed units that take the air in from the front of the vehicle and create

the least-restrictive path to the turbocharger.



Aftermarket filters-on-a-stick don?t work very well, even if the air filter element has

an enclosure around it. They still tend to take in the hot underhood air, which is far

less dense than outside ambient air. Remember, just because an aftermarket airbox system

or filter-on-a-stick makes more noise, doesn?t mean its making power or increasing air

density. Make sure you get a dynamometer-tested airbox that actually makes power and

increases air density instead of just making more noise.

How is it working out for you so far. I am really happy with my DPP intake system. Wouldn't buy a TAG III again, bust the rest is top notch stuff. Plus it makes sense at to why it makes power and brings cooler air into the truck. My EGT's while running about 70 on flat ground are around 400-450 post turbo, so I think it is working correctly. I would reccomend them to friends. Scotty

On launches you can't tell the difference. But towing heavy on heavy grades in 2-3 gear at higher RPMs it seems to really put the power to the ground.
