When I got my car the previous owner had installed a Trick Flow intake. When he installed the throttle body and EGR spacer he used RTV instead of gaskets and it looked kinda crappy so I decided to take them off clean them up and put gaskets on. I went to the parts store and they had the throttle body to EGR spacer gasket , but not the EGR spacer to intake gasket. Since I am not running EGR or EGR coolant lines anymore I just got two of the Throttle body to EGR spacer gasket and used in both places, seems to work fine.
