Air Intakes vs Exhaust Mods: Which Upgrade Improves Diesel MPG More?

Why Airflow Matters for Diesel MPG

Diesel engines rely on balanced air-to-fuel ratios for efficient combustion. Better airflow means better burn, lower EGTs, and improved MPG.

Air Intake Systems: Breathe In Power

Factory air intakes can restrict airflow. Upgrading provides cooler, denser air into the engine, supporting cleaner combustion and better mileage.

✅ Benefits of Intake Upgrades:

  • More air flow

  • Improved throttle response

  • Less turbo lag
