Twin Turbo Turbocharger Set for Ford F-150, Expedition & Transit 3.5L EcoBoost (2013-2016)

Twin Turbo Turbocharger Set for Ford F-150, Expedition & Transit 3.5L EcoBoost (2013-2016)

This is a set of two turbochargers, cross-referenced to OE numbers DL3E-6C879-AF and DL3E-6K682-AF, built as a matched left-and-right pair for the Ford F-150, Expedition, and Transit equipped with the 3.5L EcoBoost V6 from 2013 to 2016. If you've noticed a loss of power, boost-related trouble codes, or unusual turbo noise from your EcoBoost, replacing both turbos as a matched set addresses the twin-turbo system as the manufacturer designed it.

Why Replacing Both Turbos Together Makes Sense

The 3.5L EcoBoost uses two identically loaded turbochargers working in tandem, so when one begins to wear or fail, the other has typically seen the same mileage and operating stress and often isn't far behind. Replacing both turbos as a matched set, rather than just the one that failed first, helps ensure balanced boost delivery on both sides of the engine and reduces the odds of needing a second turbo repair shortly after the first.

Compatibility

Built for the Ford F-150, Expedition, and Transit equipped with the 3.5L EcoBoost V6 from 2013 to 2016. Because Ford used the 3.5L EcoBoost across several truck and van configurations during this period, it's worth confirming the OE numbers above against your original turbos or reaching out with your VIN before ordering to help guarantee a correct fit.

Signs Your Turbochargers Are Failing

A noticeable drop in power or acceleration, a whining or whistling noise from the engine bay that changes with RPM, boost-related check engine codes, or a rattling sound when the engine is off are all common signs of failing turbochargers on the EcoBoost engine. Because these engines rely so heavily on turbo boost for their power output, a failing turbo tends to produce a more noticeable performance drop here than on a naturally aspirated engine.

Why Replacing Both Turbos Promptly Matters

A turbocharger that fails internally can send metal debris into the intake system, risking damage to the engine well beyond the turbo itself if left unaddressed. Replacing both turbos as a set when one starts showing signs of wear helps you avoid that secondary damage and restores the balanced power delivery your EcoBoost engine was designed around.

Installation Notes

Installing this set means removing the engine covers and surrounding components for access on both sides of the engine, disconnecting the oil, coolant, intake, and exhaust connections, unbolting the old turbos, and installing the new units with fresh gaskets before reconnecting everything. Because a turbocharger needs immediate oil supply once the engine starts, priming the oil feed lines before startup and letting the engine idle briefly after installation helps protect the new turbos on their first spin. Given the complexity of accessing both sides of this engine, professional installation is worth considering for this job. Once both turbos are installed, a careful check for oil, coolant, and boost leaks around every reconnected fitting helps confirm the job was done right before you're back on the road.
