Construction & Design

The Banks Ram-Air Intake is built with high-quality materials engineered to withstand the rigors of heavy-duty use. The intake housing is molded from XLPE, a lightweight yet robust plastic that provides excellent thermal insulation to reduce heat soak. This ensures the air entering your engine remains cool and dense, which is critical for diesel performance.

The oversized airbox is carefully designed to maximize the volume of ambient air around the filter, while the dry "Big Ass Filter" element offers superior filtration efficiency and longevity without the mess of oiling. The entire system is precision-engineered to fit perfectly with the OEM ram-air scoop, maintaining a factory-like appearance and function.

Performance & Sound

By increasing mass air flow by 51% over the stock intake, the Banks Ram-Air Intake significantly improves engine breathing, resulting in better throttle response and reduced turbo lag. This translates to more immediate power delivery and improved fuel efficiency during sustained heavy loads. Additionally, the intake produces a deeper, more aggressive induction sound that enhances the driving experience without being intrusive.
