The Vibrant -4AN to 1/8 in NPT oil restrictor fitting kit offers a compact way to reduce oil feed to a turbocharger. The aluminum adapter includes stainless steel inserts and two threaded jets (0.030 and 0.045 in.) for customizable oil flow; without a restrictor the opening measures 0.060 in. Intended to help protect turbo seals, the kit carries a one-year limited warranty.
