air induction kits

did anyone think of doing there own air induction kit?? im workin on designing one and hope to get it done this weekend, im gonna try to run two hoses of the intake manifold and have it funnel down to one big hose or tube into a k/n cone type filter. i would leave the bottom half of the air box there to draw in cold air to the open element air filter. maybe i will even go with a little bigger tubing running to the bottom half of the air box to draw in even more cold air. it would save me 150 bucks for a fpik kit or other name brand kit. i already have an older k/n filter so that would be the cheepest part. any idea's comments???

Better yet, anyone come up with a clean looking snorkel kit yet? I'm getting tired of digging small fish and water bugs out of my airbog. Actually, I'm toying with fab'ing up my own air induction kit that will prevent water from entering the airbox when I'm in water deeper than the front bumper. I haven't had any problems yet, but I don't want to run into any either. Any ideas?

I tried cutting out the bottom ofthe airbox on my 96. I cut a mating hole in the fender liner and put a 4" dia tube thru it. the idea was to get to a cold air source with less flow restriction. It didn't work. The fenderwell turns out to be a low pressure area and it actually REDUCED air flow to the engine. I lost 0.2 in the 1/4 by my "improvement." This winter, I'm planning on hooking up a duct to the botom of the air box (same 4" hole) and routing it thru the wheel well to the slot in the front bumper, which is a high pressure area.

TRAILDAWG,

The last time you were on here you mentioned getting a chip to see if it would wake your motor up anymore, have you changed anything? Are you still around 217hp and 365tq? Just curious

update: well i found a way to do it with pvc and rubber flex tube. it added some more power at higher speeds than low becuase of the tubing at the grill that blows air across the filter.
it gives a cool sound just above 2000 for a couple rpm then fades away.

ill update later on with mpg info and such

Cool! How about a cost/component list, rough instructions and tips on where to buy it all. Looks better than what I tried. I went to a muffler shop and had them fab a Y that fits on the ends of the stock intake hoses and then the one-tube end of the Y had a K&N canniser filter on the end. Truck ran like a r**** ape, but the speed density PCM never did adjust for the improved air flow and MPG suffered, so I abandoned the project. Let me know how yours does over time, mpg wise. Oh yeah, what did you do with the stock airbox? Is it still there? How about the breather tube that comes off the valve cover (front) and goes into the airbox? 2many questions, I know...but I'm real interested in this.

Looks good phat....especially like the trick custom painted duct tape :P Now I just have to adapt your idea to make myself a snorkle unit Is that a standard Y-junction there before the filter, or did you angle cut and plastic weld standard PCV?

well total cost was 22 bucks, i already had the cone filter off of an expedition that we had, yes its a y pipe just before the cone and like a 15-30* elbow on the firewall side. the ductape was needed cause everything didnt quit fit right. lol quick fix.

heres the parts list:
filter
3"-2" flex tubing
pvc y 1 1/2" little elbow say 15 to 30* on the firewall side.
pvc tubing 1 1/2"
2 flex tubes 2"
i bought everyting from homer depot
i went to a local parts store and the guy suggested a y pipe from exaust but i didnt want to go that route.

hope this helps

well i kept the bottom half of the air box and took off the top so the breather tube is still there. i left bottom half because if u notice it runs down to the grill and helps to pull air in and over/around the filter effectiflly lowering the intake air temp. hence alittle gain. i also cut off the little flap at the end of the intake tube by the grill

p.s. one last part, a small coffe can to put inside the 3" tubing and the end of the filter so you have something to tighten the hose clapms on.
