The stock airbox pulls fresh air from towards the bottom of the engine compartment, yes? Would it make a difference to angle the cone filter down sightly, towards the opening where the stock airbox pulls fresh (cold) air? It seems like, when the truck is moving, outside air would be forced into the cone.
The original factory air feed comes thru a roughly 3x3 hole behind the headlight assembly. So any unit that routs the cone to that area is going to benefit from that factory design. Also any unit that has some sort of heat shield will be better. Though routed to the proper area, the MAC lacked this shield, thus my rudimentary modification. I feel this shield performs two functions 1st it blocks radiated heat 2nd it catches, traps and directs the incoming airflow around and near the cone. The mac also is steel which absorbs and holds heat. Some say this heat is enough to compromise combustion. At idle on a hot a$$ day i agree, at a trot N/A. At 2500 to 3000 RPM then dropped into passing gear she rolls.
Every one of those are for a 4.0 Sport or Sport track.....Will they work on a 4 door XLT? Am I thinking the right direction here....Cold air intake of some sort and maybe soon an aftermarket exhaust. Make more air comes in and more air goes out????? A little more hp and possibly a little better mpg's????

definitely... if u modify the intake, modifying the exhaust will work in conjunction with the decreased backpressure... go for it and ull be able to tell the difference... i recommend getting ur stock muffler cut out and getting a new one welded in... im running a flowmaster 40 but its a bit loud so id suggest a flowmaster 50... its a bit quieter at idle
Keep in mind the amount of modification your going to do to your truck. Cai's became popular from the import tuner crowd. Does a 4 cylinder need a cai? no. Does a heavily modified 4 cylinder pushing 500 hp need a cai? You bet. It is at the stage where the engine NEEDS more air. Not just wants it. Does your engine need more air or do you just want it. Also think about the overall factory design. I had a '87 Honda Accord and it benifited greatly from a cai. both in hp and mpg. But that is because the factory setup had 11 twist and turns from air box to the manifold. Also the airbox had a hole that a pencil wouldnt fit through for the air to come in. It needed less restriction due to poor original design. I doubt modern engines are designed with restrictive intakes like this. If you do decide to use a cai because your running a lot of hp, have airflow restriction, or just want it to look good, there are several products you can use to dissipate heat. There is a wrap you can put on your intake tube to keep the tube itself and the air in it cooler. Also use a heat shield like seadawg used. Also check into either ceramicoated headers or there is a heat wrap thats kinda like a roll of paper but its a thick material and it can be wrapped around your headers. That will make keep entire engine bay cooler. Good luck & have fun.
I think I know how to make a working cold air intake, I just have to take care of a few other projects, first.
From researching, I don't think an underhood unit, no matter how well insulated, or one that drafts from the wheel well, is going to 'help'. May sound better, but the heat issue remains.
I gotta say, I can no longer feel the weight of the vehicle with a new exhaust system and the cai. The vehicle accelerates like a sports car - does the vehicle need all of this? No, but it is dang fun! Scr## mpg!
What is the part number of that one. I am a firm believer in K&N Filters and Kits after the last four vehicles that I have had such set ups on. I have had K&N FIPK Gen II kits on '95 Civic and an '01 Dodge 1500, with a K&N drop-in filter in a '92 Toyota Pickup. And now I want one on my 2004 X-XLT 4.0L.
All proved to have noticeable, seat of pants dyno tested, improvements in throttle response. The only issue that I have ever had with any kit like this I generally refer to as "LEAD FOOT SYNDROME"...It sounds so good and feels so right that you just can't keep that heavy lead right foot out of the throttle! In my Dodge, the problem was diagnosed to be the greatest, but the Honda and Toyota showed improvements in MPG...The Honda got 32-33 before and 35 after consistently on the freeway.
