i have a 2003 f150 4.2L v6. i was looking for an airraid throttle body spacer for my truck and i found a few. What is the difference between the 1997-2000 throttle body spacer and the 2001-2003 throttle body spacer??? are they different designs??? thanks for any help.

 

Easy, one sucks and one blows.

Seriously though, the only FI engines I've ever heard of getting a real benefit from those are TBI motors. why wouldn't you just get the one for the 03's if you want one(out of curiosity)?

Now that I've said my piece... If you look here it has picture of each, the most notable diff. (to me) being the gaskets:

i didnt buy one yet, but thanks for the info.

 

Check the 3.8 & 4.2 section. Those guys really know their stuff when it comes to making the 4.2 faster/more fuel efficient etc... Some of them have even posted times on wether or not it helps, I think the general consensus is that they aren't worth the money.
