Perrin Performance Turbo Sump Restrictor

Part #: PSP-ENG-630

Overview

The Perrin Turbo Sump Restrictor is a specially designed component for Subaru WRX models from 2018 to 2023. This part is engineered to address common oil consumption issues that can occur after installing aftermarket exhaust systems such as cat-back, j-pipe, or turbo-back setups. When these modifications alter exhaust pressure, it can lead to engine oil escaping past turbo seals, resulting in burning oil smells and blue smoke from the exhaust. The Perrin sump restrictor helps mitigate this problem by controlling oil flow and maintaining proper pressure within the turbo system, supporting engine longevity and consistent performance. It is ideal for enthusiasts seeking a reliable solution to oil consumption issues caused by increased exhaust pressure, ensuring their vehicle runs cleaner and more efficiently.
