Product Details

If you're looking to get more out of your 2003-2007 Dodge Ram with the 5.9L Cummins engine, this Injen Evolution cold air intake is a solid option. It's designed to help your engine breathe easier, which can lead to noticeable improvements in performance. This system is built to work with your truck's stock computer, so you don't need to worry about reprogramming it.

The intake tube and housing are made from cross-linked polyethylene, a strong and durable material that can handle the heat under the hood. It includes a large, dry-element air filter that's easy to service and features a special mounting system to ensure a secure seal. The stainless steel hardware and reinforced silicone couplers mean this intake is built to last. Injen tested this system on their own dyno and found it can add up to 25 horsepower and 62 ft-lbs of torque.

Installation is designed to be straightforward, with no cutting or drilling required. You'll also get a more aggressive intake sound when you step on the gas, which many owners appreciate.
