Ford Fiesta Parts & Accessories

The Ford Fiesta has been sold globally in multiple generations since 1976 and returned to the North American market from 2011 through 2019, delivering an entry-level subcompact with strong fuel economy and, in ST trim, genuine hot-hatch performance credentials. The sixth-generation Fiesta ST uses a 1.6-liter EcoBoost turbocharged four-cylinder rated at 197 horsepower paired with a Torsen limited-slip front differential, a combination that made it a benchmark handler in its class. Earlier North American Fiestas from the early 1980s used a simple pushrod 1.6-liter engine and front-wheel drive layout that still has a small but dedicated following. This collection covers maintenance, repair, and performance upgrade parts for every North American Fiesta generation.

Popular Upgrades

Fiesta ST owners most commonly pursue ECU tunes from Mountune, Cobb Accessport, and EcoTune that push the 1.6 EcoBoost beyond 220 horsepower, along with Mountune MP215 and MP235 upgrade packages that include intercooler upgrades, cold air intakes, and exhaust systems. Öhlins, Bilstein B8, and Fortune Auto coilover kits are popular for lowering the Fiesta ST's already capable suspension for autocross or track days. Inlet elbow replacements, forge motorsport atmospheric venting blow-off valves, and aluminum charge pipes are high-demand accessories for the boosted EcoBoost platform.

Performance and Handling

The Fiesta rides on a front MacPherson strut and rear twist-beam suspension architecture that delivers impressive lateral stiffness for a subcompact, especially in ST guise where Ford fitted stiffer springs, larger sway bars, and Recaro sport seats from the factory. Lowering spring kits from Eibach, H&R, and Tein are available for standard and ST Fiesta models with approximately 25mm drop while maintaining acceptable ride quality. Camber correction bolts for the front strut tower are recommended whenever the Fiesta is lowered to preserve tire wear and alignment angles.

What is the best tune for the Fiesta ST?

Mountune's Cobb-based OTS and ProTune maps are the most popular choices for Fiesta ST owners because they are engineered specifically for the 1.6 EcoBoost and maintain reasonable drivability while adding 20 to 40 horsepower depending on supporting mods. Cobb Accessport Stage 1 maps work on a stock Fiesta ST and can be refined with a custom tune once an intake and exhaust are added. EcoTune and AmD Tuning also produce well-regarded maps for the 1.6 EcoBoost that have been validated on Fiesta STs in both street and track configurations.

Does the Fiesta ST have a limited-slip differential?

Yes, the Fiesta ST came from the factory with a Quaife-sourced Torsen mechanical limited-slip differential integrated into the front transaxle, which significantly improves traction and cornering exit performance compared to a standard open diff. The Torsen unit requires specific gear oil at the correct viscosity and quantity, and fluid changes are recommended every 30,000 miles on cars used in spirited driving or track events. Aftermarket Quaife and Wavetrac units are available as replacements if the factory diff shows signs of wear.

Why These Parts Fit Right

Parts in this collection are organized by Fiesta generation, trim level, and engine code to separate the EcoBoost ST fitments from the base 1.0 and 1.6 Ti-VCT applications. Fitment notes distinguish between the sixth-generation 2011 to 2019 North American Fiesta and the earlier 1978 to 1981 models so your order is correct for your specific car. Fast shipping means your Fiesta is back on the road or track quickly.
