2004 Dodge Ram Cummins

Installing an aftermarket air-intake system is one of the most common upgrades for a diesel truck. It promises to increase airflow for more power and better fuel economy, and it will often change the sound of your engine and the exhaust note. Many diesel truck owners will eject the stock intake as the first step in their buildup because it can be done at home with common handtools, and it gives you a reason to pop the hood and show-off the powerplant. With so many diesel intakes available, we decided to round up five that can be used on an '04-1/2 Dodge Ram. We will bring you our test results in a future issue. Until then, let's take a look at the features and specifications that make these intakes special.
