Revainrating 5 out of 5

Easy Install & Fuel Pressure Booster

I have checked my pressure from 6.0 to 45psi and after installing this item it is a good 65psi so I can be sure it has made an improvement. I tested under load and never went below 50, so I'm very happy with this supplement. Easy installation, took about an hour after watching some YouTube videos. I've had to replace injectors before so I'm hoping this will help prevent another premature failure.

Pros
  • Automotive
Cons
