Fuel Economy Package

1998–2002 5.9L Cummins (24V)

This Fuel Economy Package is built for 2nd-gen Cummins owners who want better MPG, lower EGTs, stronger throttle response, and improved towing efficiency without sacrificing reliability. Every component in this package was selected to reduce restriction, improve airflow, and stabilize fuel delivery — the keys to real-world fuel mileage gains.

What’s Included:

• Monster Ram Air Intake System
  Improves airflow and throttle response while reducing intake restriction under load.

• S&B Cold Air Intake
  High-flow filtration with sealed airbox design to keep intake temps down and efficiency up.

• XDP Performance Intercooler
  Larger core volume and improved cooling efficiency to lower intake air temps and EGTs, especially when towing.

• FASS Fuel System (Stock–700 HP)
  Stabilizes fuel pressure, removes air and contaminants from fuel, and protects injectors — critical for efficiency and longevity.

• BD Exhaust Manifold
  Eliminates restrictive factory design, improves exhaust flow, and helps balance exhaust temperatures across cylinders.

• 4” Turbo-Back Exhaust System
  Reduces backpressure, lowers EGTs, and allows the turbo to work more efficiently.

Why This Package Works:

• Improved airflow in and out of the engine

• Cooler intake temps and exhaust temps

• Consistent fuel pressure under all driving conditions

• Reduced engine load during cruising and towing

Expected Results:

• Fuel economy gains: typically +1–3 MPG (driving style dependent)

• Lower EGTs when towing

• Better throttle response and drivability

• Increased engine and injector longevity
