Just throwing out a few pics of the additional filtering capacity I have added to my 05.

I have an Amsoil remote oil bypass kit with a home made mount and location I came up with originally on my 02 and integrated it to my 05. behind that you can see the Fuel filter kit I installed from Vulcan performance with a 3 micron Donaldson filter between the OEM filter and the CP3.

 

 

Yes it does, but with modern oils soot is even harder to filter out. 

 

A lot has to do with engine design. My latest UOA was <0.1% soot but that is with the 03-04 piston bowl. The lowest I ever saw on the 05 pistons, at 7,500 miles, was 1.6% and the lowest ever was 0.9% at 5600 miles.
