3.4? Yup your going to need quite a bit done unless you plan in replacing your motor.


First and foremost you need something to scan knock with Aka a scan gauge II or aeroforce.

3.6 is a better start. Headers,intake,tune,180 Tstat.

A 3.4 will require the about plus something major like a Intercooler or Cam.

Btw this has been answered so many times please search next time.
