When you buy a 6.7L Cummins–powered Ram, you’re already working with one of the most reliable diesel engines ever built. Whether you're towing, daily driving, or planning a performance build, the right upgrades will dramatically improve power, reliability, and drivability.

Here are the Top 6 first mods every 6.7L Cummins owner should consider — with links to our most popular Cummins collections so you can shop fast and easy.

1. Intake Upgrade — Better Airflow, Better Performance

The stock Cummins intake restricts airflow and limits power. Upgrading improves throttle response, reduces EGTs, and supports future mods.

What to look for:

✔ High-flow designs
✔ Smooth inlet paths
✔ Reduced turbo lag
✔ Trusted brands (Banks, S&B, AFE)

2. Exhaust & Turbo Backpressure Upgrades

Freeing up exhaust flow allows your turbo to spool faster and keeps EGTs under control — especially important for towing or tuned trucks.

3. Fuel System Protection (FASS / AirDog)

Air vapor, low fuel pressure, and dirty fuel kill injectors.
A quality lift pump is one of the best reliability mods you can buy.

Monitoring tools like the CTS3, Banks iDash, or Edge Pulsar protect your investment and keep your tuning safe.
