Deal Torque Solution Turbo Sump Restrictor 2015-2021 WRX / 2014-2018 Forester XT

Description

The Torque Solution Turbo Sump Restrictor is an effective solution for FA20DIT engines that develop oil smoke or burning oil smells after installing aftermarket exhaust components. When exhaust upgrades reduce engine back pressure, excess oil can pass through the turbo seals and enter the exhaust, resulting in blue smoke and unpleasant odors.

This restrictor restores proper pressure balance within the turbo oil return system, helping prevent oil from pushing past the seals. The result is cleaner operation, reduced oil burning, and smoke-free enjoyment of your WRX or Forester XT.

Precision machined from 6061 billet aluminum and finished in a durable black anodized coating, the Torque Solution Turbo Sump Restrictor is built to last. Stainless steel clamps are included for a secure and straightforward installation, and the product is backed by a limited lifetime warranty for added peace of mind.

Installation:
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.
