No Limit Fabrication Cold Air Intakes: Purpose-Built for PowerStroke Diesel Performance
Cold air intakes are where No Limit Fabrication got its start—and it shows in every product they build. Founded in 2011, the company traces its roots directly to the cold air intake category: owner Mike Dillehay began by handcrafting custom intakes in his garage to fill a gap in the market for 6.4 PowerStroke owners running higher-than-stock boost levels. That garage-born expertise has since evolved into one of the most respected names in diesel performance fabrication.
What separates No Limit Fab from mass-market intake brands is the combination of true American manufacturing, precision-machined aluminum construction, and fitment engineered specifically for Ford’s Power Stroke diesel platform. Their cold air intake lineup spans multiple PowerStroke generations—including the 6.0L, 6.4L, and 6.7L engines—giving Ford Super Duty and F-250/F-350 owners a tailored upgrade path regardless of model year.
Stage 1 and Stage 2 Intake Options
No Limit Fab structures their cold air intake offerings into distinct performance tiers. The Stage 1 intakes are designed as direct factory replacements that install in the stock airbox location, making them an accessible first upgrade for trucks with the factory EGR cooler still in place. These kits arrive partially pre-assembled and are engineered to improve airflow, throttle response, and fuel economy over the restrictive OEM setup—often in under 30 minutes of install time.
For builds demanding maximum airflow, No Limit’s Stage 2 open-element intakes take things further. The 5-inch aluminum intake tube pairs with a massive 5.5” x 12” conical AFE filter element—engineered to be among the most free-flowing options available for the 6.7 Power Stroke. Drivers pushing elevated boost levels get the unrestricted air volume their builds demand without sacrificing fitment quality.
Aluminum Construction and Filter Media Choices
Every No Limit Fab intake tube is machined from aluminum and available in a range of finishes, including raw, polished, and custom color options. Filter media flexibility is another hallmark: buyers can choose from popular AFE filter types including Pro5R oiled, ProDryS dry, and ProGuard 7 media depending on their operating environment. For trucks used in dusty, off-road, or farming conditions, No Limit also offers a water-repellant, dust-stopping custom pre-filter available in multiple colors—a thoughtful touch for trucks that see real work.
The 4.5-inch aluminum open air intake for the 2020–2023 6.7L PowerStroke is particularly notable as an industry-first design for that generation, delivering improved horsepower, torque, and throttle response in a package that sits comfortably at the factory intake location. Select fitments also carry CARB certification (EO # D-837-1), making them legal for use in California.
Who These Intakes Are Built For
No Limit Fab cold air intakes are purpose-designed for Ford Super Duty diesel owners who want real performance gains backed by genuine American craftsmanship. Whether you’re building a street-driven daily driver or a high-boost performance truck, the tiered Stage 1 and Stage 2 lineup means there’s an option matched to your goals.
