Awlright youse guys, where do I find a lower-temp thermostat for the UrQ? Stock is 190F/86C (thereabouts); I would like to cut 20F off of the temperature, say 170F/75C (thereabouts). Audi lists no other thermostat to fit that car . . . Also, MSD no longer makes their knock sensor; anyone know of any other companies who make a "stand alone" knock sensor/warning display? -RDH
