installing cone air filter
hey guys, i got one of those cone shaped air filters for my 5.8L. I did some research and if I am correct, i just attach the temp sensor from the stock air filter box just somewhere near the new filter? It's okay if it's exposed?

You dont say what year you have. I installed a K+N cone shaped filter in my 351. All I needed was 6" of 3" stainless pipe. You can look at my gallerie for a picture. But there is no temp sensor in my stock filter. I will assume that your's is newer. I'm sure you can figure it out.

Temp sensor? Huh? MAF sensor maybe, but the temp sensor is mounted in the lower intake manifold near the thermostat waterneck.
On a side note, I personally would avoid any induction setup that draws in air from under the hood. The idea is to pull in cooler air not warmer regardless of the volume. And too increasing volume isn't always recomended since the velocity of the air is mantained by a certian amount of restriction in the induction system. Take care if the filter element uses oil as a filtration element. Your 96 is MAF injected. The oil can be pulled into the MAF sensor and destroy it. Its worth it to make absolutely certain this won't become an issue since a bad MAF sensor wreaks all sorts of havoc. Just a couple of "devil's advocate" thoughts to keep in mind.

oh man i can't get a straight answer on just what kind of sensor that is that plugs into the top half of the filter box. whatever that sensor is it needs to be relocated. i'm finding out that somefolks just put their's beneath the new cone. so, just what is that sensor? i read it reads the temp of the air coming in through the filter, most are referring to it as a temp sensor.

The sensor your talking about is the Air charge temp. sensor (ACT) Checkout the link below a lot of helpfull info. on Ford fuelinjection.

I use to think this way also, but if you look at the stock setup, It draws hot air in from under the hood. Its not getting any ram air where it located. The way I did my K+N, ram air is ducted right to the filter. At slow speed it may not get enough to feed the engine. But I think at highway speeds it should get cooler air. It would be intreasting to put a temp guage at both locations. Maybe when I get some time. In any caes, I think I got about 1/2 a mpg. Although that could be due to lots of veriables.

Insulating the OEM airbox and using a drop-in K&N produces lower intake air temps than underhood induction systems. Thats not an opinion. Check www.performanceunlimited.com and look up "Project MPG". The truck used in the tests was a Centurion conversion but the induction setup is identical to any other fuel injected F-series.
By the way, what part of your induction system is missing? The end of the intake duct is mounted to the top of the upper radiator cross member. The only way to get any closer to pulling air from outisde would be to extend that duct out the grill. Ram air isn't necessary... its nice to have if you can get it but cool air is still better than hot.

I had the upper intake tube you are refuring to. But when you close the hood it is cut off from the cool air in front. It will just suck hot air at the top of your hood. If you check the thred in your post, you will find that it doesnt have the same intake as a Bronco!! The upper tube your talking about is replaced with a ram air setup on the side of the rad, like I have installed. This must be the stock setup for that truck. Now that I see it, I plan to hunt one down in a junkyard. It would look alot better than drier ducts. I'm betting Ford figured out the tube on top of the rad was picking up hot air.
The other interesting thing in this thred is the highest hp is attained with the cone filter. (but not the highest milage) I think that is because they didnt have any cool air ducted to the filter. (and they did with the stock setup)
I admit that I may have to build a box around the cone filter so no under hood air mixes with the cool air I have ducted to it.

well guys, sorry to revive an old thread but i have to say. my truck HATED that damn cone filter i put on. i swear i was at the gas station every other day!! needless to say, i put my stock air box in with a drop in K&N, everything is good now. thanks for you guys' input!!

On my '94 I have K&N drop in filter, air inlet tube going BESIDE the radiator that is for a F-250 with a 460, '92to ?. It made a big difference in highway power before I changed plugs, timing chain and advanced the timing. The air inlet tube was $18 at Ford however a recent post said they were no longer available. You might try Ford anyway before the junk yards to save time.

I could not agree more graystreak - and every test out there will show that with COOLER (and cool air is denser) air you will generate more horsepower.
What normally happens with these aftermarket systems that remove the stock airbox and use underhood air is MORE NOISE and that makes those that may be less intelligent THINK that they have more HP now that the engine makes MORE NOISE.
Sorry if I stepped on any toes here - but trust me if there were easy (and FREE) hp to be gained, don't you think the factory would have already done it to give them more bragging (IE selling) rights over the competition ?
About the only thing that needs to be changed or modified on the stock Ford CAI system is to increase the airflow up by the radiator - the air box and filter are plenty big as they come from the factory for any non race truck engine out there.
The ONLY advantage to a KN filter is the reusability - great if you live in a dusty area.
Some IMO and some factual! David

I'm not sure I follow. The test that Greystreak mentions shows that the cone filter generates the most HP. It is an independant test. (K&N didnt do it) The factory often has done stupid things that rob power for all sorts of reasons. While I agree cooler air is better, certainlly a freeier flowing filter could and does make a differnce. Although it may not be enough to feel.
