PERRIN 15-17 & 2025 Only Subaru WRX / 14-16 Forester XT Turbo Sump Restrictor - Black

If you're pushing your 2015-2017 or 2025 Subaru WRX, or your 2014-2016 Forester XT, hard through corners, you might worry about oil starvation to the turbo. This Perrin turbo sump restrictor is designed to help keep that from happening. It works by controlling the flow of oil back to the sump, ensuring your turbo stays properly lubricated even during aggressive driving.

This restrictor is made from well-built aluminum and finished in black. It's a straightforward part that installs into the oil drain line of your turbo. The goal is to maintain a small amount of oil in the turbo's bearing housing, which is crucial for keeping the turbo cool and preventing damage, especially when you're experiencing high G-forces that can cause oil to slosh away from the pickup point.

For those who track their car or participate in autocross events, this is a popular addition to help protect your turbocharger. It's a small part that can make a big difference in the longevity of your turbo under demanding conditions.
