Best EcoBoost Bolt-Ons, Ranked

The bolt-on upgrades that deliver the most for a Ford EcoBoost, ranked — downpipe, cold air intake, tuner, and intercooler for the 2.7 and 3.5.

These are the EcoBoost bolt-ons that deliver the most real-world gain per dollar on the 2.7 and 3.5, ranked. New parts are on Amazon; used and OEM options are on eBay Motors via the buttons above.

1. Tuner

A tuner is the highest-impact single upgrade — more boost, torque, and throttle response, plus live monitoring for towing. It also makes every other bolt-on more effective. Start here.

2. Intercooler

An upgraded intercooler beats heat-soak and keeps intake temps down, so the tune can make and hold power on sustained pulls. Pair it with aluminum charge pipes so nothing splits under the added boost.

3. Catted Downpipe

A catted downpipe frees the turbos for quicker spool and better flow, with a deeper tone. One of the biggest gains alongside a tune.

4. Cold Air Intake

A cold air intake feeds the turbos cooler, denser air and sharpens throttle response — the finishing touch on a well-rounded EcoBoost.

Frequently Asked Questions

What order should I install EcoBoost bolt-ons?
A tuner first unlocks the most gain and lets the other parts do their job. Add an intercooler and upgraded charge pipes to keep boost cool and contained, then a catted downpipe to free the turbos, and a cold air intake to sharpen response. Retune after adding hardware for the best results.
Do EcoBoost bolt-ons need a tune to work?
Intercoolers, charge pipes, and intakes are safe on a stock tune, but they shine with one. A downpipe generally wants a tune to clear codes and take full advantage of the freed-up flow. A tuner is the piece that ties everything together.
Will bolt-ons hurt reliability?
Done sensibly, no — a bigger intercooler and upgraded charge pipes actually improve reliability by controlling heat and stopping boost leaks. Keep the tune conservative and the supporting parts matched to your power level.
