Fresh Mods to my '08 Sport Trac

what is the part number of the k n filter system? Do yo think it adds any more power?

I believe 77-2573KP is the one I used. I don't know that it gives it much more power. It certainly looks cool under the hood. One thing to think about. If you don't change your exhaust to something more aggressive, the CAI makes your V8 sound like a wounded water buffalo when you give it the gas.
 






Oh yea, throttle definitely feels different, and the acceleration and sound are real nice.

This is the one I bought. It says that it does not fit the '08 Sport Tracs, but it fits the '08 Explorer, and the STs have the same engine compartment and configuration as the Explorers. My FIPK just popped right into my '08 ST.
