PERRIN 18-24 Subaru WRX / 20- 25 LGT/OBXT/Ascent / 17-18 Forester XT Turbo Sump Restrictor - Black

Made from anodized aluminum, this sump restrictor from Perrin is designed to manage oil flow to your turbocharger. It's a small but important piece for turbocharged Subarus, helping to ensure the turbo gets the right amount of oil without over-supplying it, which can lead to issues like oil burning or seal damage. This restrictor is specifically engineered to work with the factory turbocharger on many Subaru models.

Proper oil flow is critical for turbo longevity. Too much oil can overwhelm the turbo's seals, leading to oil consumption, while too little can cause premature wear. This Perrin restrictor is a well-built component that helps maintain that balance, especially after modifications or when replacing turbo components. It's a straightforward part to install, often done when servicing the turbo or related oil lines.
