Product Overview

Cobb Tuning Stage 2 Power Package w/ AccessPort V3 14 Fiesta ST

The Stage 2 Power Package for the Ford Fiesta ST is the best second level for the Ecoboost powered vehicle. During exhaustive testing, the COBB engineers found that heat, not necessarily airflow, was the biggest restriction to power on the platform. As such, they married a Front Mount Intercooler which is 55% larger to our 3" plastic molded intake kit. This setup cools temps as much as 100 degrees, and produces significant power. Everything is tuned right out of the box with the Accessport and pre-installed maps. The Stage 2 Power Pack has max gains of +14% HP and +29% LB-FT on 93 octane fuel. The Stage 2 Power Pack includes:

  • COBB Accessport V3
  • Intake System
  • FMIC (Front Mount Intercooler)
  • Rear Motor Mount
  • COBB Vehicle Badge
  Peak Gains Maximum Gains
Stage2 91 7% 22% 12% 27%
Stage2 93 9% 24% 14% 29%

Peak Gains are measured as the absolute maximum value between the highest points of two plots. Max Gains are measured as the largest gain at a single point between the two plots.

Results may vary. Power as tested on 2014 Fiesta ST vehicles using these identical calibrations. Generally speaking,  91 octane calibrations have a richer fuel curve, and a less aggressive ignition advance map to help compensate for lower  octane fuel blends such as those found in Arizona, California, and Nevada; and/or less than ideal atmospheric conditions.  The maps designed for 93 octane are the most aggressive.

*91 and 93 octane results are compared against a 93 octane fuel baseline.  Your 91 octane results may be higher than listed   above; as a baseline of 91 octane fuel may read lower than our 93 octane baseline.
