not sure what IIRC means but ok, yeah i've thought about getting one and just having it done so i dont have to deal with it later. 195 degrees is the recommended thermo i assume??? i see everyone putting 180 degrees thermos in their car, but i also heard rumor that it could affect performance, not sure if its true or not but just thought i would ask as well. i have a 195 thermo in there right now.
