The 7.3L Power Stroke is commonly regarded as possibly the best power stroke engine that Ford has made to date. It wasn’t plagued with the problems of the 6.0, nor was it weighed down by the emission junk that was found in the 6.4 and the 6.7 power strokes. These factors and more allow the 7.3 to have incredible reliability and power capability, making it an excellent powerplant that lasts for a very long time.
Singing my praises for the 7.3 aside, we all know how good it is, but there are still a few things that can be done to improve it beyond what Ford engineered it to do. The best mods for these engines have to do with reliability, adding power, and improving MPGs. A lot of them are quite simple, effective, and cheap, and will work wonders to transform your truck to another level of performance.

GlowShift Air Intake Heater Boost Plug Sensor Thread Adapter
This mod allows you to remove the restrictive air intake heater out of the flow of incoming boost.
This heater is only activated at low ambient temps while the truck is idling for an extanded time, so 90% of drivers won’t even know its gone. The conditions for when it runs are as follows: oil temps below 131°F, glow plugs off, trans in park/neutral, parking brake on, charging system between 11.5 and 15.0 volts, and ambient temp below 32°F.
For how little it runs, it’s a lot better to pull that big heater element out and replace it with this plug, which also allows you to easily add an aftermarket boost pressure sensor.
