Viper designed without A/C standard (92, 93, and all ACRs) have an undrestricted oil-filter-to-oil cooler line. This results in higher oil pressures at idle and at speed, and better oil cooling. (Downside in COLD weather is that you should warm the car to temp) A/C designed Viper have a mechanical shuttle valve in the line that STOPS oil cooling below 17-23 PSI.
THis is to protect the A/C condensor from oil cooler heat.
The adapter is highly recommended for any RT10/GTS that does frequent track or Auto-X events....and if you have Gen II 96-99, you NEED a higher capacity pan as well... No detriment to A/C, but the A/C will trip off line frequently of the oilcooler is very hot.
