Know Which 7.3 You Have

The 7.3 ran for almost ten years and Ford changed a lot along the way. The OBS trucks (1994.5 to 1997) and the Super Duty trucks (1999 to 2003) use different turbos, injectors and intake parts, and the 1999.5 and later trucks added an intercooler. Always check fitment by year and build date before you order. If you are not sure, send us your VIN and we will match the part.

What to Fix First

Before you add power, get the common failure points handled. A bad cam position sensor, a chafed UVCH harness or a weak IDM will cause hard starts, misfires and stalling, and no tune will fix that. Leaking up pipes cost you boost and add turbo lag. On 1999 to 2003 trucks, check the HPOP STC fitting for oil leaks. Once the basics are right, tuning, injectors and a turbo upgrade all do their job better. Read our 7.3 Powerstroke upgrade guide for the full order of operations.

7.3 Powerstroke FAQ

What years did Ford use the 7.3 Powerstroke?

The 7.3L Powerstroke was used from 1994.5 through 2003 in Ford F250 and F350 pickups, the 2000 to 2003 Excursion and E series vans.

What is the most common 7.3 Powerstroke problem?

The cam position sensor is the most common no start and stalling issue. The under valve cover harness (UVCH) and the injector driver module (IDM) are close behind.

What is the best first upgrade for a 7.3 Powerstroke?

Fix any fuel pressure, sensor or harness problems first. After that, a good tune and a free flowing exhaust are the best value for most trucks.

Do OBS and Super Duty 7.3 parts interchange?

Some do, but many do not. Turbos, injectors, intake parts and many sensors are different between the two, so always order by year.
