The AMS Turbo Inlet Tubes are a performance-driven upgrade designed to eliminate the restrictive airflow bottlenecks found in the factory turbo inlet plumbing on 2017–2020 Ford F-150 Raptor and F150 3.5L EcoBoost engines. By massively enlarging the cross-sectional area where the stock tubes choke airflow, AMS’ engineered tubes dramatically reduce pre-turbo restriction and pressure drop, allowing the twin turbos to spool more efficiently and produce more power with less effort. Testing has shown upwards of 20 additional horsepower when paired with proper tuning, making this a foundational upgrade for tuned, off-road, or performance Raptor builds. Precision-formed and designed to retain all OEM fittings and compatibility with stock or aftermarket intake systems, these inlet tubes deliver both measurable performance gains and a subtle, OEM-integrated look under the hood.
