Cool Home made cold air intake box.

So I built and air intake for my old F250 (no longer w/me) but I always wanted to take it to the next level, relocate the battery and built a cold air box for the filter!

I wanted to built something fast and dont give it too much though since there was a lot going on with the new truck I got (F350 dually), so I came up with a simple plan but had to stop about 3 times due to work. The plan was as follows:


1. Super cheap,
2. use as much left over material as I can
3. no special orders, just homedepot materials
4. find a good location for the battery. I end up building a braket to hold a northentool battery box drivers side next to the transmission.
5. I went to the junk yard and good the positive battery lead out of a E36 BMW for $13
6. mokup the filter in it's final resting possition.
7. built the 3" intake pipe from exhaust piping. my goal was to make it smooth as possible, the less bends the better
8. built the box with some alumi left over and some fine sheet metal from home depot.
9. I knew in the summer the metal will get hot so I wanted to have some foam to isolate the heat.
10. tape it all up with foil tape, make sure the intake temp sensor reads the air box temps.
11. make sure I had a good unrestricted inlet from the grill to feed ambient air temp in to my box
12. make sure I can pop up the hood and visually inspect the filter.


I'm about 80% happy with it, I know it could be way better and perhaps some one here takes it even further, but I'm okay if it last 2-3yrs.

I've driven around in the rain, in about 30 degrees weather, and the air box has stayed at ambient temp, I'll wait how it goes in the summer

Some pics to make sense of all this blahbing!!!!

Sorry to tell you the best air filter for the 6.0L in the factory setup,
The best part is the ''Zoodad mod'', but it needs a screen over it, dont hate me ....

You're wrong on both accounts... but believe what you want.

Custom intake looks good, RJ. Most people don't build a box for their filter, let alone design a zoodad funnel. Very cool. I did the zoodad mod on my last truck and never installed a screen, and I went thru some HEAVY rain at times. Never had an issue. Then again, the possibility of my intake sucking in too much water was in the back of my mind...

Sorry I'm not too familiar with the OE system in the 6.0L.

The air filters are so cheap and I tow maybe once every 2mos with my truck that I rather have unrestricted air flow (no screen) to increase the chances of creating a high pressure around the filter.

Yes, my truck is a 2000 F350

I dunno if it's a "lot" of time consider all of the other work I had to do to this truck

When we bough it we knew it was a fixer-Upper, but I think I have on/off about 16hrs including the 1hr round trip to the local junk yard for the battery cable.

In a perfect world the best intake system will have the same air flow at WOT b4 the filter and at the throttle body. In FI'd applications the best system is the one that yields the same power with no filter on the turbo, while the turbo is feed with ambient air.

The next thing I might do is to wrap the intake pipe with heather wrap, then seal it with foil tape to prevent heat soaking, at that point I'm making sure the inlet of the turbo is getting abient temp air.

I can not testified how un restricted is the paper filter, but that is where I made the call base on my background. In racing the best filters are paper, the big down side of them is that they do not last long, thus the air filter technology has driftted to alter materials such as gause, foam, etc.....

I've hands on exp with dyno tuning race cars, and I've observed that foam filters such as ITG work as good as having no filter at all when NEW! after some used their performance drops while the paper filter stays conssistent longer. Now, K&N type filters some perform as good as paper, but some others can not perform as good as paper; the good thing is that they are reusable!

Thank you,
