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!!!!
