The AMS Performance 2021+ Ford F-150 and Raptor 3.5L EcoBoost Turbo Inlet Tubes are engineered to unlock airflow your truck has been leaving on the table by eliminating the restrictive factory inlet bottleneck between the intake system and the turbochargers.

With up to 158 percent larger cross sectional area than the OEM tubes and organically shaped flow paths that maintain smooth airflow through direction changes, these inlet tubes dramatically reduce pressure drop at the compressor covers and deliver up to 2.6 PSI less inlet restriction at equivalent power levels. The improved airflow allows the turbochargers to operate more efficiently with lower shaft speeds, reduced charge air and exhaust gas temperatures, and less overall turbo stress, while also creating additional headroom for higher power levels once tuned.

Designed to integrate seamlessly with the factory intake system and most aftermarket intakes, the AMS Turbo Inlet Tubes retain all OEM fittings and connections while maintaining an OEM look and feel, delivering a clean installation and a measurable performance upgrade for any 3.5L EcoBoost F-150 or Raptor.

ENGINEERED TO WIN

When evaluating the factory turbo inlet tubes on the 2021+ Ford F-150 and Raptor 3.5L EcoBoost platform, our SnailWorks® Engineering Team identified a significant airflow bottleneck ahead of the turbocharger compressor inlets. The OEM tubes prioritize packaging and manufacturing considerations, limiting the cross sectional area feeding the turbochargers. This restriction increases pressure drop before the compressor covers and forces the turbos to work harder to achieve the same boost levels.

To address this limitation, our engineers redesigned the inlet geometry with significantly larger internal diameters and optimized transitions that maintain smooth airflow through directional changes. The factory bottleneck diameter of roughly 40 mm has been increased to over 65 mm, resulting in up to a 158% increase in cross sectional area over the OEM inlet tubes and dramatically improving airflow capacity to the turbochargers.

Extensive CAD development and real-world testing were used to refine the design and minimize pressure drop throughout the inlet path. The tubes maintain a large diameter as far down to the turbo inlet as possible before smoothly guiding airflow into the compressor cover, promoting even airflow distribution into the turbocharger.

Compatibility and ease of installation were also key priorities. The AMS Turbo Inlet Tubes retain all OEM fittings and connections while integrating with the factory intake system and most aftermarket intake options. Our engineers also developed notched silicone couplers that align with the inlet tubes, allowing the components to be perfectly oriented correctly during installation and making clocking the tubes in the tight engine bay significantly easier. The end result is a high performance inlet system that improves airflow while maintaining OEM-level fit, function, and appearance in the engine bay.

DATA DRIVEN DESIGN

At AMS, product development is driven by real-world data. Our development vehicles are equipped with a MoTeC dash data logger and a 19-sensor array that monitors critical engine and turbocharger parameters in real time. This instrumentation allows our engineers to capture detailed data during dyno testing and on-road validation, ensuring every design decision is based on measurable performance improvements.

During development of the AMS Turbo Inlet Tubes, our team monitored key system parameters including compressor outlet temperature, charge air temperature, turbine inlet pressure, drive pressure ratio, and exhaust gas temperature across both turbocharger banks to understand how inlet restriction affects the entire turbo system.

Testing on a 2022 Ford F-150 Raptor 3.5L EcoBoost equipped with an AMS Intake, AMS Intercooler, and 93 octane calibration showed clear improvements across these channels when the AMS inlet tubes were installed. With reduced restriction ahead of the compressor, the turbochargers operated at lower pressure ratios and reduced shaft speeds while producing the same manifold pressure, resulting in lower compressor outlet temperatures and reduced thermal load on the intercooler system.

Lower compressor workload also reduced turbine demand, producing lower turbine inlet pressure and a more favorable drive pressure ratio. This allows exhaust gases to exit the cylinders more efficiently and helps reduce exhaust gas temperatures during equivalent power runs.

One of the most important indicators of intake system restriction is pressure drop ahead of the turbocharger compressor. Ideally, pressure at the compressor inlet should remain as close to atmospheric as possible. At approximately 470 wheel horsepower, the AMS Turbo Inlet Tubes reduced turbo inlet pressure drop by up to 2.6 PSI compared to the OEM inlet tubes, with no calibration changes between runs. The AMS F150 Turbo Inlet Tubes also delivered nearly identical airflow results across both banks, demonstrating how well-matched the system is as a paired set. Balanced airflow between turbochargers promotes more consistent engine performance and more predictable ECU calibration.

Reducing restriction at the compressor inlet lowers the pressure ratio required to produce the same boost level. This allows the turbochargers to operate in a more efficient region of the compressor map, which reduces shaft speed and compressor outlet temperature. Lower turbo workload also reduces turbine inlet pressure and exhaust backpressure, helping improve engine efficiency and durability while increasing available airflow headroom for higher power levels.

TEST BENCH RESULTS THAT SPEAK FOR THEMSELVES

To quantify airflow gains with absolute precision, our AMS SnailWorks® Engineering Team ran the OEM intake tubes, a leading competitor’s offering, and the AMS F150 Turbo Inlet Tubes through our state-of-the-art MAF-based flowbench. Using MoTeC instrumentation to capture real-time pressure and airflow data, each inlet tube was tested under identical, repeatable conditions simulating the airflow demands of a ~500 WHP 3.5L EcoBoost engine.

The results were unmistakable. The factory intake tubes struggled, showing –2.05 psi of depression on the right intake tract, a clear sign of significant restriction. The competitor system performed marginally better but still exhibited notable pressure drop. In contrast, the AMS Turbo Inlet Tubes demonstrated a dramatic improvement with only –1.18 psi of depression at the same airflow level, representing up to a 42.4% reduction in restriction versus OEM. At any given pressure drop, the AMS system consistently flowed more air than both stock and competitor offerings, making it the least restrictive inlet tube solution in the test group.

The data speaks for itself: if you’re seeking maximum airflow and horsepower potential, the AMS Performance 2021+ Ford Raptor and F-150 3.5L EcoBoost Turbo Inlet Tubes stand alone at the top.

Good privacy screen
Size: 1 Panel, Size: 1 Panel
This is a good privacy screen that's easy to assemble and looks nice. Be a little careful moving it, as the corners can twist. It's sturdy once in place, and the thick material is completely opaque. If the folds bother you, you might want to iron it, but I'm happy with it as is.

Lightweight divider that works well for video call backgrounds
Size: 1 Panel
This divider works fine for what it is, but it’s definitely on the lightweight side. Setup was very easy and only took a few minutes. The frame is fairly light, so it’s easy to move around or reposition if needed. That said, the tradeoff is that it’s not especially sturdy. It stands fine on its own but I wouldn’t expect it to handle much bumping or movement. I mainly bought it to use as a background for Zoom calls when I’m working from my den, and for that purpose it works great. The fabric panel blocks the room behind me and gives a cleaner background on camera. It’s not huge though. To keep the camera from seeing around it, I have to position it directly behind my chair. If you’re expecting it to divide a large room or create a big privacy barrier, it may feel a bit small. Overall, it does the job and works well for temporary setups or video call backgrounds, but the lightweight frame keeps it from feeling like a premium divider. The product description and photos are accurate.

Sent Wrong Pieces
Size: 1 Panel, Size: 1 Panel
I really, really wanted to like this - and, in theory, I really, really should have! The instructions were easy to follow and assembly took about five minutes. The assembled screen is lightweight and easy to move. It was a great size and exactly what I was looking for except....I wasn't sent the correct pieces. Instead of receiving 4 elbow pieces and 4 feet, I received 2 elbow pieces and 8 feet - meaning that the bottom part of the fabric just hangs there and, overall, the divider is extremely unstable because there is no horizontal support on the bottom. Thankfully, there are Velcro tabs on the side of the fabric so I can use it if I don't plan to move it even 1 cm, but otherwise, what I received is not usable for what I needed it for. Additionally, the fabric is made of polyester and catches animal hair very easily. Had I received the correct pieces, this would be a good buy for the money. Unfortunately, overall, I'm disappointed.

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.
