The only thermostat listed at any of the part stores that I went to was 195. The last place I went looked up a 1998 5.4 and found a 180 thermostat listed. No gasket is needed it has an o-ring that I reused. I didn't get any performance gain that I could tell. I just don't have the supercharger loss of boost now.

 

Hi Lightning Kid
I saw you zip by on Sunday. Yea he must have meant OBDII. You know that you can turn it off with a chip. A least with an Auto Logic chip.
