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 systems. Installing these parts 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 there 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.
