Choose the appropriate oil feed adapters to fit your turbo.

These restrictor flare jets are used w/ the restrictor holders to reduce the flow of oil to the turbo when needed to reduce oil leaks and smoking. These Jets when used w/ Restrictor Holder (available separately) are assembled to form a -4 AN male flare - use with a -4 AN oil supply hose.
