why not make my own?
i was looking around for a cold air intake for my 4.0 liter and was suprised at the prices. I took a closer look at them and it looks like if i had the filter, tubing, and flex fitings i could easily make myself for less then half the money it cost for a name brand.
it looks like there are only two bends that i have to deal with. This seems straight forward but is there anything that i am over looking? Is there really more to a CAI than just a better flowing tube?
BTW, i realize i'll have to make a port for the MAF sensor.
i'd like any thoughts you guys have on the idea...thanks

I will also look into making my own. I'm in the middle of the axle swap and some other little stuff, so it's one of the next mods on my list. I am going to keep the stock air box (w/ mod where I cut the hole bigger) with my K&N because I dont want mud and water to get into the intake as easy. I think most of the power is gained when you add the smooth intake tube.

^that is pretty much exactly what i was planning on doing. I thought about it and i believe i need to go with AL or stainless due to the possibility of rust with steel. yeah i'll have to find an adapter to take the 2 3/4" to a 3" and find a conic filter.
another thing i was pondering was where the gain comes from. I mean the location of the intake will be right where the original air box was so not much difference in air temp. Also the stock tube is pretty smooth so i don't think thats it. I can only conclude that the gain is from less resistance due to the filter and its exposed surface area.
anyone else have an idea?

basically.. ya the box theoretically only has a cirtian amount of reserve air inside untill it has to use effort to pull air through the little tube.. but the problem is with an open conical filter and no box or heat shield your now breathing superheated exhaust air.. give and take, me personaly im going to make the stock hole biggar and make some sort of ram air because ill take cold air over better flowing filter and hot air..

I have seen folks make the maf adapter out of a toilet flange maybe...?? It is a square plastic fitting about an 1/8 or 1/4 thick that have a round pipe hole in the middle. They used their dremel to cut it down to the same shape as the maf and them mounted it up. I will see if I can find the pixs.

For the reducer/adapter from 2.75" to 3", you can get a silicone fitting for that. They're pricy though, and you'll need clamps.
Something like this:

K&N makes a nice cone filter with a 3" diameter. I have one on the Focus and it sure does suck (in a good way). And its easy to clean.
Something along these lines:

I have just about the same size one on the Focus, just its a bit shorter from the looks of that picture (mine is about 8" long)
Not sure how much space you have to deal with, but you may need a shorter length filter.
And if you can't get it out of the engine bay, you can probably fabricate something like this:

The MAF.. no idea :(
hope that helps you out a bit!

coming from hondas this is fairly common ,all of the available aftermarket cold air kits i have seen for the ranger are short ram..and has been proven on hondas anyways ( don't see why any different on fords as all engine are just basically air pumps) that a true cold air kit ( filter located outside the engine compartment) makes more low/ mid while the short ram style is more top end .. being that the 4.0 makes more power down low than a honda 1.5/1.6 makes more sense to have the filter located outside the engine compartment instead, as no one i have seen makes this style for the ranger only way is to diy
