Not sure if it works or not, but if you have to have the separate IAT sensor. I think they combined them for '02 with the MAF. It will not work on those w/o the separate IAT.

 

great mod if your looking to get a new engine soon. here is a hint, with you get what you pay for and there is a reason a good tuner cost hundreds not singles

 

WOW that thing looks like crap. Looks like a peice of paper with the letters "Speed Seeker" were taped onto a black box with wires sticking out.

 

All it is, is a resistor, you could get the resistor itself at radio shack for less than a buck. It makes your car think ita a different temp outside therefore runs richer or leaner than it normally would be, you cazn lose HP with them too,, I did research a while back to try and figure out how it worked, that is what I came up with.
