15+ WRX / 14+ FXT Turbo Sump Restrictor by Torque Solution

Torque Solution Turbo Sump Restrictor for Subaru WRX 2015+ / Forester XT 2014+ is the perfect solution to help fix your FA DIT engine from smoking / burning oil after installing your aftermarket exhaust components.

Due to the reduced engine back pressure from the upgraded exhaust oil tends to go past the turbo seals. This leads to having a burning oil smell and blue smoke coming out the exhaust. Our restrictor works by bringing proper pressure balance back to the oil return system resulting in smell and smoke free enjoyment of your WRX or Forester XT.

Please Note: This restrictor installs inline (arrows facing up) on the turbo sump vent hose that runs from the turbo sump to the front engine cover. Any location on the hose is fine as long as there is approx. 3/4" of hose above and below the restrictor.
