99+ cars do not have a separate intake air temp sensor. This is because its built into the maf as one unit.

Score one for Dustin. I just went out and looked at my car and it doesn't have one either. Like I said I did not do the install. The last mustang I worked on had one so I assumed wrong in thinking that mine had it too.


Dustin are you sure about the 99 + cars in the video I posted above of the guy installing the AM intake he is re-attaching one and there is a pic on a parts website I was just looking at (don't know what the year is exactly other than it is a 99+ and it too has one.

I am just curious as can be now myself because why did Ford change that.

He's right, it's built in. I had to plug up a hole in my intake because I don't have one. I think he 01's have it, but none others do. It's only one year that have a separate one

lol i did the exact same thing...nice man

haha, good work.

ya mine dont have one either i stuck a valve stem in it to plug it up lol

it fit perfectly

hey dude,, justa quickie, do the 3.9's have any major differences in power or sound or anything from the 3.8?

99-00 had the air temperature sensor. 01+ don't so you need to plug the hole

well 4.6 cars its 99+ I guess in the 3.8 its 01+.

no difference i got 3 more hp
