Review on 🔧 Perrin Performance Turbo Sump Restrictor - PSP-ENG-628 by James Ramirez

Revainrating 5 out of 5

Install on 2017 WRX

Got a 2017 Wrx. The easiest way to install is to remove the left hand radiator fan, use a sharp knife and cut about an inch below the sensor and then about a half inch or any width of the throttle. I just used the two large brackets that were provided. I did not use an elevator or remove the hose. Pretty simple build.

Pros
  • Replacement Parts
Cons
  • Unbelievable Price
