Banks Ram-Air® Intake system
On W-Series Workhorse motorhomes, Banks Ram-Air intake system replaces the constricted stock setup for up to 66% more airflow than stock. The high-flow Ram-Air filter does away with intake obstructions so more cool, dense ram-air can make its way into the cylinders. The filter housing cover and tubing are larger than stock to enhance flow. And the Banks adapter enlarges the air filter box inlet to significantly improve airflow and power output.

Accolades
“The word "engineering" is very important here because Banks is not just reselling someone else’s products. They have full time in-house engineers and technicians, performing their own research and development on every different type of performance option you can imagine.”
