Turbocharger Pair for Ford Expedition,F-150 (2018-2020) 3.5L Left & Right

Direct-Fit Replacement Turbocharger Pair for 2018-2020 Ford Expedition & F-150 (P552/U553)

What it Does: The replacement turbocharger pair restores factory boost pressure, exhaust flow efficiency, and spool dynamics on 2018-2020 Ford Expedition and F-150 models equipped with the twin-turbocharged 3.5L EcoBoost engine.

The Stock Ford EcoBoost Wastegate & Journal Bearing Wear

Under heavy towing loads and persistent thermal cycling, the factory BorgWarner units on the 3.5L EcoBoost suffer from internal carbon coking in the oil feed galleys, degrading the journal bearings and dynamic piston ring seals. Extended duty cycles frequently cause internal wastegate linkage play, leading to persistent boost rattle, erratic MAP sensor readings, blow-by past the turbine seal, and sluggish spool response on high-mileage P552 and U553 platforms.

The Engineering Solution

This matched left and right K03 turbocharger assembly is engineered to restore OE volumetric efficiency. Each unit features a dynamic, high-speed VSR-balanced rotating assembly utilizing heat-resistant Inconel turbine wheels and ductile cast-iron exhaust housings designed to endure continuous exhaust gas temperatures up to 950°C. Precision-machined oil and coolant ports directly match OEM hardware, eliminating the risk of flange warping and ensuring direct integration with factory charge pipes and downpipes matching JL3Z-6K682-C and JL7Z-6K682-A specifications.
