The old body style (OBS) 1994-97 Ford 7.3 Powerstroke was the first real version of the turbocharged direct injection Powerstroke and performed great back in the day. Even now, these trucks are sought after by many for their reliability and power potential. However, there are two main areas that need to be addressed on the OBS 7.3L Powerstroke: fuel and air. The factory fuel system on these trucks is woefully inadequate and can't support anything more than mild modifications. Likewise, the factory air intake is restrictive and doesn't allow the engine to breathe properly. Fortunately, there are a number of aftermarket parts available that can address these issues. For example, fuel system upgrades like larger injectors and lift pumps can help to support increased power levels, while upgraded intake kits can help to improve airflow. With the right modifications, an OBS Powerstroke can easily hold its own against newer trucks. Best of all, with FFD Performance Parts' renowned customer service, it's easy to keep your truck running its best for years to come.
