2015-2017 Subaru WRX and 2014-2018 Subaru Forester XT Turbo Sump Restrictor by Perrin

Many customers experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turbo back exhaust systems. Installing these parts on 2015+ WRXs (FA DIT engine) causes a change in exhaust pressure, allowing engine oil to escape out the turbo seals. This leaks into the exhaust creating the burning oil smell and blue smoke that many people see.

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 in any way.

Since drivers have been installing turbo back exhausts on 2015+ FA DIT WRXs, there have been both burning oil smell and blue exhaust smoke issues. After a short period of time, we found a great solution in the form of the PERRIN Turbo Sump Restrictor. We wanted to make sure we could come up with an effective solution and tested our solution over the course of two years. We now feel confident releasing this product to the public!
