let me just say that when i pulled my OE filter & changed it (even thought
the indicator was not prompting me to do such early maint.)
i dumped SAND out of it....NO FILTER is gonna filter as well for as long...
sandy dust/dirt will rip the edges right off that compressor wheel !
NO ONE has EVER proven that the stock airfilter is a choke point for
this engine...now ill agree at some point, heavy hp moding or
competition pulling, will benefit from more air...but thats about
WINNING not about longevity.
Donaldson, the mfg of the factory air filter, has produced flow reports
and filtration information indicating that the filter can flow more
air than even a moderately modified 6.0L engine consumes
all the aftermarket cheez-cloth/oil "charged" filter mfg tell you their filter
works BETTER once it collects some DIRT...so you gotta ask...wheres
the initial dirt GOING before it builds up on the filter !?!
and if that werent enough they tell you to CLEAN IT...which starts
the dirt passing cycle all over again !
