K&N has developed an air intake system (57-1557) for 2007, 2008 and 2009 Dodge Ram 2500 & 3500 pickups with 6.7 liter diesel engines.  K&N dynamometer testing shows a 20.63 horsepower gain at 2500 rpm and a 43.35lbft gain of torque @ 2500 rpm. This is more than a 10 percent increase in torque over the original intake for improved towing and passing power.

The 57-1557 features a specially molded intake tube and a K&N lifetime replacement filter (RC-5142). The K&N washable and reusable air filter provides increased surface area and dust capacity. The K&N air filter is made of six layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The nature of the cotton allows high volumes of airflow and exceptional filtration efficiency. With proper care diesel motors typically last much longer than gas motors. This K&N air filter provides outstanding filtration efficiency to ensure you get the protection your diesel motor needs.

Our air intake system includes a powder coated steel heat shield which isolates the K&N air filter from engine heat.  It has lower restriction than the factory air box which results in additional power and torque when you need it.

The 57-1557 is designed so the mass air sensor will work with factory stock settings. This means there is no need for re-programming to run our air intake system.

Designed to be installed in 90 minutes or less with simple hand tools, our K&N air intake systems are backed by the famous K&N Million Mile Limited Warranty.
