High-performance upgrades for 1999–2003 Ford 7.3 Powerstroke
For owners of 1999-2003 Ford 7.3L Powerstroke trucks, we offer exhaust, cold air intake, and fuel-system components built for stable operation on higher-mileage engines. Every part in this collection fits F-250 and F-350 Super Duty pickup trucks across all five model years - direct-fit kits, upgraded intakes, mufflers, and supporting hardware engineered for the 7.3 platform.
What's included in the 7.3 Powerstroke parts collection
If you're upgrading a 1999-2003 Ford 7.3 Powerstroke, you’ll get easy-to-choose, direct-fit performance parts that restore airflow, improve exhaust routing, and support stable engine operation.
-
Exhaust system upgrades - 5″ stainless turbo-back race exhaust with mandrel-bent sections, OE-style hangers that match factory mounting points, and a choice of straight-pipe or muffler setup.
-
Cold air intake and airflow components - two options: a base high-flow kit (intake tube, heat shield, high-flow filter) and the S&B enclosed-airbox system with cotton-cleanable or dry filter media. Both move more air than the factory box and keep engine heat off the incoming charge - a real difference when towing in summer.
-
Diesel mufflers - standalone 4″ and 5″ T409 stainless mufflers, useful if you're building a custom exhaust or swapping the muffler on an existing setup.
- Fuel system - the FASS frame-mounted lift pump with built-in fuel filtration and water separation, sized for the 7.3L fuel supply layout.

FAQs
Most owners start with a cold air intake and turbo-back exhaust system. This combination improves airflow, reduces EGTs, and increases turbo spool speed. For the 7.3L Ford Powerstroke engine, these upgrades provide the best performance gains relative to cost and pair well with tuning down the road.
Yes. The larger system moves heat faster and reduces load on the turbo. It also lowers exhaust pressure, which benefits older engines.
On a healthy 7.3 Powerstroke, a turbo-back or high-flow exhaust system typically adds about 10–20 horsepower and 20–40 lb-ft of torque.
Most of the gain comes from reduced exhaust backpressure and quicker turbo spool, especially when the exhaust is matched with a free-flowing intake.
It can create minor improvements by reducing intake restriction. Overall performance and fuel efficiency gains are small but throttle response becomes more consistent, especially on trucks used for towing.
Yes. Products are selected for 1999–2003 Ford models, including late-03 revisions. Fitment is matched to turbo orientation, pipe routing, and intake layout used on the final production year.
No. Delete and exhaust-removal components violate federal emissions law in the U.S. and are sold strictly for off-road or race use.
Dieselino does not sell custom tuning files or provide calibration services for the 7.3 Powerstroke. Our catalog for these trucks focuses on exhaust systems, exhaust tips, and cold air intake kits.
If you need help choosing parts or understanding installation steps, our staff can answer fitment questions and point you to the right components.
