89-98.5 Dodge Cummins 5.9L 12v

The Cummins B 5.9 was introduced in 1984 as an agriculture engine. It was not until 1989 that it became the first B-Series Cummins engine to be used in a light duty truck; the Dodge Ram. The B 5.9, also known as the "12 Valve", became a popular alternative to the V8 engines typically used in these trucks, as it generated nearly double the torque at low engine speeds and nearly doubled the fuel ecomony as well. Mid-year in 1991, the B 5.9 recieved an intercooler. The 12 valve featured Bosch Direct Fuel Injection utilized a VE injection pump between 1989 - 1993, and a P7100 injection pump between 1994 - 1998. The 12 valve 5.9 remains one of the most popular versions of the Cummins produced.
