The Ford Fiesta has been offered in several world markets outside of the US for over 40 years! Unfortunately, it wouldn’t be until the 6th generation that there was finally a variant that would ever get invited to party. That variant is the Fiesta ST.
Taking the supermini commuter Fiesta and adding more power should’ve been a recipe in Ford’s cookbook for years. Take the light, nimble chassis, slap in a larger displacement turbocharged engine, add a 6-speed transmission, and you’ve got all the ingredients you need for an enthusiast favorite. In 2013 it even won Top Gear’s “Car of the Year”!
With so much going for the Fiesta ST, it’s no surprise it also has an extensive supply of aftermarket parts.
COBB has been tuning the Fiesta ST since its debut in 2013. The 1.6l EcoBoost 4 cylinder engine is ripe for tuning. COBB had already had a jumpstart on supporting the vehicle as the direct injected turbocharged platform borrowed the foundation from the Mazdaspeed 3 for which support was already well established.
COBB Tuning approaches design by taking the entire vehicle-platform into account as a complete exhaust system. Our ultra-high-quality performance products and services are professionally engineered, thoroughly tested and backed by industry leading customer service to ensure that they meet our objectives and exceed customer expectations.
We are a one-stop firm with an enviable set of qualified skills and the exceptional ability to design, engineer, manufacture, test and service our own products under one roof. Whether it’s our state-of-the-art Accessport ECU programmer, our exceptional bolt-on Fiesta ST performance parts, COBB Tuning has the experience, skill and attitude to meet your Ford’s specific needs.
Our engineers rigorously test Hard Parts to find the right order and combination for the best incremental power gains. Maps are created and tested to tune the ECU so that it supports and takes advantage of each part. With these results, COBB is able to create the Upgrade Path of Staged Packages that have all the necessary parts for Fiesta ST. You can start with Stage 1 or immediately get everything and go straight to Stage 3! Learn more about The COBB Way.

The COBB Intake for the Fiesta ST takes a great airbox design and makes it even better! We improved upon the factory airbox ram air ducting by including an oiled cone filter with velocity stack to increase airflow and to hear that great turbo sound. The constrained piping to the turbo is replaced with 3″ powder coated aluminum tube to maximize air flow while custom silicone couplers ensure a perfect OEM-like fitment. Cap it off with a COBB airbox lid that increases volume and seals perfectly with the factory lower intake box.
The COBB Front Mount Intercooler (FMIC) Kit for your Fiesta ST is the easiest way to drastically improve power when coupled with tuning from the Accessport. Even when stock, the factory FMIC can be overwhelmed with heatsoak. By using a 55% larger core with streamlined piping that is a direct bolt-on solution, your Fiesta ST will come alive with charge air that’s up to 100 DEGREES COOLER. This is the single best hard part modification for your Fiesta ST.
COBB Tuning exhaust components are exactly what your Fiesta ST is looking for. The COBB Fiesta ST exhaust uses 2.5″ 304 Stainless Steel and all parts are a direct replacement for factory components. These upgrades result in a unique exhaust note that provide awesome power potential. Couple the full turboback with corresponding hard part requirements and the Accessport for the most power!
