2003 - 2007 5.9L Dodge Cummins

In 2003, Dodge 5.9L Cummins again met the challenge of producing a 305 hp engine capable of meeting the growing emissions requirements that would also be second to none in power and torque output. Cummins introduced the 325 hp "600" series engine midway through 2004 (identifiable by a red or silver tag on the drivers side of the engine that shows the torque rating at "600"). The "610" model was released in 2005, and was capable of an impressive 325 hp and 610 lb-ft of torque. The 5.9L Cummins 610 remained unchanged through 2006 and the early 2007 5.9L models. These were the first Cummins 5.9L 24-Valve engine to feature the Bosch Common Rail injection system which gets it's steady supply of fuel from a CP3 high pressure supply pump. This new technology doesn't come at a cheap price, and that's why we always recommend a FASS system to protect your investment. A variety of electronic tuners are available that can easily squeeze an additional 100 hp out of your 5.9L engine. An added benefit to electronic performance tuning is that increases in fuel economy can also be enjoyed. Throw in a cold-air intake kit, a performance exhaust system, and you've got yourself a real beast that is getting better fuel economy than it did when it left the dealership. Factory replacement or performance turbochargers are also available
