Precision Turbo Oil Feed Restrictor for Garrett Ball Bearing Turbos

Precision Turbo's Oil Feed Restrictor fitting with -4 AN Male Flare x 7/16-24 thread and a 0.035" orifice. This thread is designed to thread directly into Garrett Turbos. Turbo oil restrictors are often a necessity for ball bearing turbos to restrict the flow and pressure of the oil reaching the CHRA. By reducing this excess windage on the bearing you can achieve optimal boost response and improve the life span of the bearing and seals.
