It is critical that you run a *factory Mopar o2 sensor* in your 2.2 or 2.5 turbo powered Shelby/Dodge or Chrysler TC by Maserati.  If you decide to run a cheap aftermarket o2 sensor, you will have issues with the performance of your vehicle as those aftermarket sensors are *not scaled the same* as these factory sensors.  Do yourself a favor and pinch pennies elsewhere in your build or restoration project.  Available until our supply runs out.
