Review on πŸ”§ Perrin Performance Turbo Sump Restrictor - PSP-ENG-628 by Terrance Singletary

Revainrating 2 out of 5

Examine the product before installation.

I used this on a 2019 Wrx and it has essentially reduced oil burn in the exhaust, but because it restricts oil from the sump it looks like the hose is sweating from condensation and oil . Plus T Connect does nothing. Use only if excessive oil is being burned in the exhaust.

Pros
  • Oil Restrictor
Cons
  • Not sure
