Banks Ram-Air Intakes begin as precision CAD-designed prototypes and are extensively refined through advanced flow simulations until optimal airflow and performance are achieved. From there, a physical prototype is built and rigorously validated using flow bench testing, followed by dyno testing and real-world on-vehicle evaluation to ensure proven, repeatable gains under load. The Banks 42210 cold-air intake features a fully enclosed airbox, oversized inlet, and high-efficiency dome-shaped filter designed to dramatically improve airflow while delivering measurable gains in horsepower and fuel economy. It also helps reduce exhaust gas temperatures (EGTs) and minimizes sooty, black smoke for cleaner operation. Unlike the restrictive factory intake that pulls in hot underhood air, this system isolates cooler, denser outside air to help restore lost power and efficiency in your Ford F250, F350, or F450.
