Duramax Cold Air Intake Kits & Performance Air Filters

A lot of aftermarket companies talk about improving intake airflow. Make no mistake, good air flow does matter. But when it comes to really enhance your Duramax engine’s performance and power, flow isn’t the whole story. You’ve got to have high intake density (I.D.) because, without it, you’re leaving untold power, performance, and efficiency on the table. And that means you need cold high-flow air.

In a diesel, the turbo improves I.D. by compressing the air. The intercooler improves I.D. by cooling the air. The stock intake air system decreases density by de-compressing and then heating the air. We want to minimize that loss of density. A true cold air intake system provides cold, high-pressure air which is far richer in oxygen content, providing exactly what your engine needs. Our competitors boast about flow, but they don’t talk about temperature. And that’s the truth about a cold air intake!

The Banks Ram-Air Duramax Cold Air Intake is superior because it couples maximum flow with minimum temperature. Its huge filter, smooth passageways, and high-flow outlet mean airflow is cool, dense, and unobstructed. And like every Banks system, it’s built to last.
