Earl's Restrictor Flare Jet Holder Fitting

In some turbo systems, it may be necessary to restrict the oil supply side of the system to prevent oil leaks and smoking. Special flare jet -4 AN style jet holders are available, w/ several optional restrictors to fine tune the oiling system (similar in design to a nitrous style Flare Jet, except in a larger -4 AN size). These adjustable restrictor jets & holders may also work in some EFI applications to dampen the signal for remote mounted sensors.
