Features:
Many Subie owners experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turboback exhaust systems. Installing these parts can cause a change in exhaust pressure, allowing engine oil to escape out of the turbo seals. This leaks into the exhaust creating the burning oil smell and blue smoke that many people see.
HOW THE PERRIN PART WORKS
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.
PLUG & PLAY
Plug-and-play Sump Pump Restrictor is designed for ease of installation on most 2018 and newer Subarus. With no need for cutting hoses, installation is quick and effortless. For full instructions, click on the "Installation Guide" at the bottom of this description.
