mocfly Posted August 3, 2013 Report Share Posted August 3, 2013 While installing a new K&N Filter today I noticed that there are 3 holes on either side of the air filter which allow UNFILTERED AIR into the intake system. This seems wrong on the most basic level. Does anyone know what the filtration level of the K&N is versus the others? Cause the K&N looks like the micron level is pretty high. Is there a reason for this? Is it wrong? What is the corrective action if it is not how FD intended. Expect a LOA in the next few weeks for the installation of a Water Sep for the CTSW.
