You will most likely be running dirtier oil in your system.

You can perform an experiment like done before:

Place the filter to a shop vacuum and on the other side of the filter get some coffee filters, or something like it.

Run the vac over some shit, or dust... and look at the filter, and coffee filter.

Compare the stock one to the Ractive.

Purchase a KN filter, and try it again... you want the better flowing filter to at least filtrate a little better.

Just my $0.02
