Review on Dorman 55164 Isolator Bolt for Ford Engine Intake Manifold in Select Models by Bryce Marshall

Revainrating 5 out of 5

OEM quality at a good price!

If you have the infamous bad code issues on both banks of your 4.2 liter Ford truck and your oxygen sensors are correctly switching to real time scanner readings then this is what you need. Make sure to grab new manifold gaskets to replace while you're there. Dorman products have always worked well for me and chances are they will work for you too! I just wish they had included some docs showing correct torque for less experienced people but I think google works too lol.

Pros
  • Make sure this part is right for your vehicle by entering the make, model and trim level into Amazon Garage.
Cons
  • There are other interesting options.
