Fiesta ST Complete Ignition Upgrade Kit – Focus ST Coil Conversion

Bundle and Save!

Everything you need for the Focus ST coil swap, assembled, gapped and ready to bolt in.

The Focus ST coil conversion is one of the go-to ignition upgrades for tuned Fiesta STs, especially on ethanol and bigger turbos. Instead of sourcing coils, mounting hardware and plugs separately and gapping everything yourself, this kit shows up complete. Open the box and install.

Why this kit

• Built for boost and ethanol. One-step-colder plugs and the Focus ST coils are the standard setup for tuned, E30–E85 and big-turbo Fiesta STs.
• No gapping, no guesswork. Every plug is gapped and checked before it ships.
• Everything in one order. No hunting down parts from three different stores.

Fits: 2014–2019 Ford Fiesta ST 1.6L EcoBoost

Note: always run the plug gap your tuner recommends.
