Perrin Turbo Sump Restrictor | 2018-2023 Subaru WRX (PSP-ENG-630) Perrin Performance

2018-2023 Subaru WRX Turbo Sump Restrictor by Perrin

Many people experience a burning oil problem and blue smoke coming from their exhaust. This problem can worsen after installing a cat-back exhaust, j-pipe, or turbo-back exhaust system. The installation of these parts can cause a change in exhaust pressure that allows engine oil to escape out of the turbo seals, causing the burning oil smell and blue smoke. The Perrin turbo sump restrictor quickly eliminates this issue.

The Perrin turbo sump restrictor makes the turbo sump pump more effective at sucking oil out of the turbo sump. This in turn creates a slight vacuum on the turbo sump creating a proper balance of exhaust pressure and vacuum on the turbo seals, significantly reducing the amount of leaking around the turbo seals. This does not change the oil flow to the turbo or create any wear.

The Perrin plug-and-play sump pump restrictor is designed for ease of installation with a need for cutting hoses so installation is quick and effortless.

Turbo sump restrictors do not require adjustments or modifications to function properly. They are ready to use right out of the box and designed to work optimally without any tweaks or modifications.
