Alliant Power injectors look and perform just like the injectors
that come from Ford and
Navistar for a very good reason, the same company makes them! 
Alliant Power injectors are NEW and come with all seals and a superior warranty.  

This injector fits the following vehicles:
YEAR RANGE:     1999-2003                            
ENGINE SERIAL NUMBER:      843,990 to 5,999,999   

Navistar Note: 
Prime (Split Shot) Injector. 
Recommend replacing AD Injector in #8 cylinder
location with AE Injector to eliminate "cackle."
This became standard production in 2002.
