Perrin Turbo Sump Restrictor
Why You Want This
Many customers experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turboback exhaust systems. Installing these parts on 2015+ WRX's or 2014+ Forester XT's 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. Cars with catless J-Pipe setups experience this issue much more than cars with high-flow cats.
How The Perrin Part Works
The PERRIN Turbo Sump Restrictor makes ther 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.
Proven Effectiveness
Since drivers have been installing turbo back exhausts 2015+ FA DIT WRX's, there have been both burning oil smeel 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.

Works Great, Less Smoke
By P.W. October 15, 2022Was looking to decrease the amount of smoke during start up on my 2015 WRX. Have had access smoke on start up due to aftermarket down pipe and cat delete. Install was east, and tested over next few days. Significantly less oil smoke on start up. Works Great!

Smokeless
By JB October 8, 2022This little thing is so simple and works so well. My car has lots of mods with custom dynotune and would smoke on cold starts. Put this thing in and smoke is gone. Does what it says. Not expensive and easy to install. Perrin does it again. Thank you Subispeed! As always return customer

Amazing
By Jesse July 18, 2022I installed a bigger turbo on my 16 WRX and it started progressively smoking worse and worse to the point that I thought my turbo seals were bad. I'm talking clouds of smoke. I put this on and almost instantly the smoke was gone. Absolutely amazed.
