Diesel engines have many nuances when compared to their gas counterparts, fuel injectors being one of them. Unlike fuel injectors used on direct injection gasoline engines, diesel injectors often have a higher failure rate and shorter lifespan due to their more extreme operating conditions. When these injectors fail, it can lead to a cascade of performance issues, increased emissions issues, and even engine damage.
These are the first 4 upgrades you should make to your 2003-2007, 5.9L Cummins.
If you're just getting into the diesel game with a third-generation Cummins 5.9L you're on the right track. While people say the 12v motors are great for being able to handle lots of power and having lots of upgrades. The 24v is also a very solid choice for both of those same reasons. With more hp from stock than the 12v motors and some beefy internals, like forged rods that can handle over 800hp. There is lots of potential to be had.
It's a great truck from the factory, but if you're anything like the rest of us you're not interested in keeping it stock. Especially with the number of bolt-on upgrades available for the 5.9L. Why not make a great truck even better? Today we will show you the first 4 mods you should do to your 5.9L Cummins turbo diesel.
