Specification

Banks Ram-Air Intake feeds your 6.7L Cummins engine cooler, denser, ambient air for greater power and fuel economy. Experience the benefits of greater flow, performance, and sound over stock. Tested and validated using computational fluid dynamics software, flowbench and on-highway.

Why it is Better

Maximum Mass Air Flow

By providing denser air to the turbo, the Banks Ram-Air system reduces the work required by the compressor. The turbo can spin slower and make the same boost. This slower compressor speed also unloads the turbine, liberating horsepower otherwise lost on the exhaust stroke.

Compared to the rest, the Banks Ram-Air ^® is the only intake able to feed enough air into our Monster-Ram Intake Elbow without acting as a throttle on the engine.

When matched with a Monster-Ram Intake Elbow and 3.5in Banks Boost-Tubes, maximum engine efficiency can be achieved, bringing enhanced fuel economy and consistent power delivery.

Cold Air In

The Banks Ram-Air removes the restrictive stock S shaped plastic snorkel with a straight connection to the frontscoop.

At highway speeds or when towing, fresh cool air from outside the engine bay is constantly being forced into theairbox, keeping intake temps low and density or Mass Air Flow up.

Block The Heat

A durable and lightweight XLPE molded design insulates against external heat better than metal heat shields ortubes.

Its oversized internal volume acts as a plenum of fresh cool air that is insulated from the engine bay heat.

This reduces pressure loss in the intake and improves air density within the sealed box, maximizing power andthrottle response.
