7.3 Powerstroke Intake Manifolds 1999.5-2003
Intake manifolds offer better airflow with less restriction and
more power for the 7.3 Powerstroke. The factory system is
restrictive with very turbulent bends, hurting the performance
for any upgraded Powerstroke. An intake manifold upgrade also
allow multiple ports for adding gauges and power adders. Changing
the manifold can increase fuel mileage, increase boost, add
power, lower EGTs, and improve throttle response.
