The RC-5040 filter flows 660.91 CFM, which is more
than enough air flow for my 4.7L V8
I have had great results when using a 900-1000 cfm
filter on both the 3.9L V6 and the 5.9L V8 motors.
I have a 68.50 MM TB on order and was looking to
increease ait flow into the TB, to around 850-1000
CFM.
The K&N FIPK gets air flow from the duct coming out of
the passenger side fender. The duct is rather small,
restrictive, and mostly blocked by the PCM.
I am going to install a larger filter and remove the
heatshield, and see what happens.
