18-24 WRX / 20-25 LGT/OBXT/ASC / 17-18 FXT - Perrin Turbo Sump Restrictor

The Perrin Turbo Sump Restrictor addresses common oil burning and blue smoke issues associated with aftermarket J-pipe installations on FA-series turbocharged engines. This component enhances the turbo sump pump efficiency by generating a vacuum within the sump, balancing internal pressures against the turbo seals. Constructed from precision CNC machined aluminum, the restrictor body features a black anodized finish for superior corrosion resistance. The included barbed fittings are manufactured from nickel-plated zinc to ensure long-term durability. This plug-and-play solution requires no hose cutting or permanent modifications to the factory oiling system. It effectively prevents oil leakage past the seals without altering total oil flow or increasing component wear.
