The 12 valve Cummins engine is perhaps the most legendary diesel engine in the world. Ever since Dodge used it to power its Ram trucks in 1989, the engine has been known for its power and durability. In all of the years that have passed since then, Cummins has attracted more fans, more drivers, and even more devotees of their 12 valve engine.

The engine’s overall simple design makes it reliable and easier to maintain than more complex options, making part replacement a less difficult process. The simple design also makes it easier for hardcore diesel enthusiasts to modify it and push the engine’s performance to suit their own needs.
