I was thinking of adding a piece of hose/tubing from in front of the radiator running to the air intake on my stock air box to get some cooler air into the engine. I have a K&N filter in my stock box. Has anyone tried this, would it help? I don't see how it could hurt anything. It would not enter the engine area, so the air introduced would be cooler. Thoughts, thanks.

 

i dont know if the 5.2 has it but on the 4.7 the ac lines are right in the way so you can't get past the fan shroud w/o flattening the pipe. with the stock setup there is a snorkel going to the fender i think that air is pretty cold, just get a bigger 4'' pipe/hose and maybe seal it off from the engine bay. i used dryer hose cause im cheap lol.

 

We probably have a similiar set up, I have a snorkey that goes to the fender also. Thanks for the suggestion.

 

I tell you what, I do not want to seem to be post hijacking in anyway.. but would love to see where this leads.. I've wondered the same thing..

on the 97' (what i have) 5.2 right besides the A/C & Rad, in between a sensor coming off the AC system or what ever that is.. and an AC Line, there is enough room you could have a 4" inlet..

I seen a photo online, i did not save, but the idea was the same, (Excet that photo he used ducktape to secure it and seal it off ROFL!)

But if we could find some sort of inlet that we could 'mount' right there that would not ust be a round tube, but rather smooth to catch the air then push in into the hose, it could act the same as a hood scoop or induction.. (Right word?)

There is plenty of room to do something like this with a little work and engineering..

Could we boht search online and see what we can find and who ever finds the parts that work and sets up first wins?

That is wasted space there and would be perfect to and would technically work as far as getting air in.. max flow to the filter.. Let me see if i can find some sort of picture.

 

This might work..

 

I think I could make something.. 4" port tube, and some hosing.. or find a one off part.. I think I'm going to look into this..

 

I have a piece of hose I put throught the area behind and over my headlight and routed it down to the right of my AC lines in front of the radiator. I ran it into the snorkel. If I could find the right thing, you can remove the snorkel. The pic above looks interesting. If there was a good place to run it you cold possibly use some downspout to run up to the snorkel. I have now had a chance to crawl under the truck and look to see if this was feasible. It has been very cold here, 1 degree this morning.

 

it will look stupid but it works, i wrapped my intake tube with tin foil. prevents the tube from absorbing the heat given off by the engine.

 

Whatever works! You could also spray foam the outside of the tube and wrap it, more insulation the better.

 

Gentlemen,
I have done this exact mod - only a test bed to see if it helped so it's not pretty" but initial results are positive. I took a piece of 3 inch PVC with a flared end, cut it a little to fit nicely and placed it in the original hole in my airbox. It's about 15 inches long and I had to cut a hole in the black shroud behind the grill to get it some clean air. I have a 3.9 with the K&N also and it seems to have given my truck a little extra pep, especially at highway speeds (which "seems" logical due to the ram effect). I made the mistake of several minor mods at once (removed front driveshaft, added the much-debated throttle body spacer - "free" to me - and installed new plugs) and I'm not sure which one may have caused my improvements but this was one I saw no drawbacks to... Next is replacement of the clutch fan with a Taurus fan to try to get some more down-low pep. I also have a Cummins 4bt in my garage that I'm working on too so that's going to be my next major mod to the truck...
Back to the subject though, the burning question I've had, and haven't had the opportunity to test it, is will I have poor results driving in a downpour?
Hope this helps,
PB
