Care to elaborate on that, Bush? I don't see too many people on this board trashing the stock Donaldson. Why would you trash ALL the aftermarket filters? When I clean and oil mine, I always look into the intake tube, and have never seen dirt or dust. Even with the zoodad and nothing more than simple screen covering the snout. Yet if the stock system isn't put together perfectly you can let alot of debris in. Not looking for an argument, but alot of us have gotten past the "Stock is best" thing and have had good results.
well in GENERAL im talking about the "gauze" type element based....
but basically ANY filter that lets more AIR IN, will have to let more DIRT in...
care needs to be taken no matter WHAT you use...but w/ the donaldson
filter supporting 500+ hp i see no reason to replace it....the stock filter
is far from being a choke point on these motors.
even K&N tells you their filter performs "BETTER" once its dirty...which
begs the question...wheres the initial dirt GO...until enough dirt is
built up for the filter to "FILTER" !?!
my point is...STILL....folks are more worried about a pyro probe breaking
than they are about using a good air filter or getting the seal correct on the
factory filter...the air filter makers convienently forget to tell folks about
the damage that can be done to the turbocharger compressor fins !
