Note: This part is not CARB exempt at this time and is not legal for sale in California


MANUFACTURER PART # PSP-ENG-630


Fix both the burning oil smell and blue exhaust smoke problems associated with your WRX turboback exhaust or Stage 2 and higher WRX by installing the 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 Turbo-back exhaust system.  Installing these parts on 2015+ WRX (FADIT Engine) cause 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 this Perrin parts works:
The Perrin Turbo Sump Restrictor makes the turbo sump pump more effective at the sucking oil out 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 any way..
