I've always refered to it as the air dam. I had to get one from Ford a while back and told them "that little plastic thingie under the front bumper" He said "Oh yeah the air dam" and thats what showed up, so thats what I'm going with The car will run hot without this piece attached too.
I have heard it called air dam, air shiled, radiator deflector shield. You can get one at any ford dealership for like 15$. You can also buy one online at www.50resto.com for 11 + 4-5 s/h fee.
thanks law i just ordered it from 50resto.com... cost me 17.50 all together. The local ford parts garage is always twice as high as they should be... I paid 17 dollars for the seal for the pipe going into the gas tank there (usually like 3 dollars from what i here).
For anybody else this is what the discription was: 1994-03 Radiator Air Deflector
hmmm... i dont have one of those, all i have is two little black flaps on both sides of the bumper do you think this would make a difference if i got a chin spoiler?
ok, i just went through this whole process. the air deflector is held in by these little plastic push-in screws. its real easy to put them in (although you might need a pair of pliers if the old ones are busted off and stuck in the holes) anyways, i ordered mine from 5.0 Resto as well, and it shows up without the push pins. luckily i went to my local ford dealer and the parts guy gave me a handfull for free. just tell them what it's for and if you really want, bring the air deflector with you to make sure the pins are about the right size. hope this helps.
