Banks Power Ram-Air Cold Air Intake - Chevy/GMC Duramax Diesel

The Banks Ram-Air gives a Duramax a sealed cold-air intake that feeds the turbo cooler, denser air without the heat soak you get from an open filter. The housing, oversized filter and smooth ducting are designed in CFD software, checked on the flowbench, then proven on the dyno and the road before Banks puts its name on it.

On the 2017-2019 L5P, Banks rates it at 70% more flow than stock and +20 hp on its own, or +81 hp total when paired with a Banks Derringer tuner. More airflow also leans out the mixture, which Banks says reduces soot and stretches the time between DPF regens. Older trucks see gains too: up to +39 hp / +69 lb-ft on the LLY/LBZ, and 57% more flow on the LB7.

Why we like it

• Fully enclosed housing blocks hot under-hood air
• Oversized filter, the largest in its class on the L5P
• Less soot and fewer regens on the L5P
• CARB EO D-161-146 on every version
• 5-year limited warranty
