Building the ULTIMATE 2018 Subaru WRX STI - Part 3

 

In today's episode of throtl, we get our 2018 Subaru WRX STI prepared for the dyno by upgrading its fuel system to accommodate for the increase in horsepower. To upgrade the fuel system, we got a new fuel pump from Deatschwerks, 1200cc fuel injectors from Fuel Injector Clinic, and a flex-fuel kit from Delicious Tuning. Check out the video below to see the installation process of all these new parts!
