Unlock the performance of your 6.6L Duramax with the Banks Ram-Air Oiled Intake System. Designed specifically for 2017-2019 Chevrolet Silverado HD and GMC Sierra HD models, this enclosed cold air intake delivers significantly greater airflow than the restrictive factory intake while maintaining excellent engine protection.

Featuring Banks' oversized reusable Big-Ass oiled air filter, the system draws cool outside air through a sealed housing to reduce intake temperatures and improve combustion efficiency. The result is sharper throttle response, improved turbocharger performance and gains of up to 20 horsepower on a stock vehicle. When combined with a Banks Derringer Tuner, total gains of up to 81 horsepower are possible.

The Banks Ram-Air system also helps reduce soot production by improving the engine's air-to-fuel ratio, potentially extending the interval between DPF regeneration cycles. Engineered using extensive CFD modelling and flow bench testing, every component is designed to maximise airflow without sacrificing filtration or reliability.
