The stock 6.7 Cummins engine is undoubtedly great, but there’s room for improvement. The diesel truck parts aftermarket is vast and full of upgrade options for your 6.7 Cummins truck. Cummins performance parts can improve your engine in different ways: adding power, efficiency, reliability, and potentially better gas mileage. You can also find ways to increase your truck’s horsepower and torque or improve its longevity. With the right 6.7 Cummins upgrades, anything is possible.
Check out this ProSource guide for some of the best upgrades for your 6.7 Cummins truck.
Section One: Upgrades for 2007.5 – 2012 Cummins
The 24-valve 6.7-liter Cummins diesel engine was launched in mid-2007. Out of the factory, it generated 650 pound-feet of torque or 610 pound-feet, depending on automatic or manual transmission. By the end of 2012, this engine had 800 pound-feet of torque. It also included a DPF (diesel particulate filter) to comply with EPA standards.
These featured upgrades can increase your turbo power, cooling capacity, and performance tuning capabilities.
SPOOLOGIC HE351VE Upgraded Compressor Housing Kit
Your turbo needs airflow to run cleanly and effectively. Unfortunately, this engine’s stock compression wheel is notorious for causing surge and lag on the initial acceleration. This Spoologic kit corrects this and boosts limits by 5-7 PSI. It also improves performance at higher boost levels.
BanksPower Intercooler Upgrade Kit For 2007.5 – 2012 Cummins
This kit improves your stock intercooler system with larger boost tubes, tanks, and inlet/outlet, plus a thicker core. The larger, more efficient cooling system will provide your engine with colder, denser air.
This improves its cooling capacity and overall airflow. The denser air also provides more oxygen, making combustion easier. All this means more engine power, lower exhaust gas temperatures, and improved fuel economy.
Superchips SC3050 DashPaq In-Cab Tuner
A tuner is one of the best ways to increase the performance of your 6.7 Cummins engine. This in-cab tuner features a full-color, high-resolution monitor that makes it easy to read diagnostic codes and stats. It provides all of the following readings:
Barometric pressure
Engine speed
Engine coolant temp
Fuel rail pressure
Transmission temp
Manifold air pressure
Plus much more!
Max power gains for specific 6.7 Cummins trucks with this tuner are:
– 2007.5-2009 Dodge 6.7L Cummins: +125 HP +340 lb-ft torque
– 2010-2012 Dodge 6.7L Cummins: +95 HP +270 lb-ft torque
Section Two: Upgrades For 2013 – Present Cummins
The Cummins 6.7 engine received changes in 2013. It gained a fully redesigned cooling system for Ram Heavy Duty trucks. It also included dual radiators and transmission coolers, increasing its heat rejection by 25%.
These featured upgrades increase your turbo boost system’s power and your engine’s cooling capacity.
Turbo boost upgrades are as vital for the 6.7 Cummins as for previous iterations. This part includes larger tubes for better airflow –3.5 inches versus your stock system’s 2.75 inches. You’ll give your engine more power and improved fuel economy.
Banks Intercooler Upgrade Kit For 2013 – Present Cummins
This Banks intercooler upgrade kit is comparable to the upgrade kit featured for the 2007-2012 6.7 Cummins. It operates similarly, also improving your engine’s power and fuel economy.
Using this upgrade nets you several other improvements: steady power output, reduced loss of boost pressure, lower exhaust gas temperatures, plus a dramatic uptick in air density.
If you want to extend the life of your Cummins engine, aftermarket coolers are one of the best upgrades.
Section Three: Upgrades for Both Cummins 6.7 Models
These upgrades are compatible with the current and previous generation of 6.7-liter Cummins engines. They’ll make your Cummins truck more efficient and reliable.
Compared to its 5.9-liter version, the 6.7-liter Cummins produces greater torque. If you want to improve this engine’s horsepower, you should invest in stronger head studs. The TreckTech Head Stud Kit offers the highest-in-class tensile strength at 240,000 PSI.
AirDog II-4G A6SABD426 DF-165 Air/Fuel Separation System
This next-gen fuel delivery removes water, particulates, and vapor from your diesel fuel, increasing engine power and performance. The AirDog system features a pump shaft that keeps the electric motor away from the fuel. If your seal is ever damaged or leaks, that will keep the motor safe and dry.
Bosch Upgraded Fuel Rail + Set Of 6 Fuel Injector Lines
If you want more fuel for your engine, injector and fuel rail upgrades allow that. Like improved airflow, improved fuel flow gives your engine greater power and efficiency.
