Just joined to let you all know that there is a really easy fix for stupid foam filter dusting your engine. Napa gold 6449 air filter and a 1 1/2 pvc coupler. Put the coupler inside filter and slips inside breather tube in factory air box. 2016 Kodiak 700. Put air box lid on your done. 70 cfm filter. Performance seems fine. I have dusted to many engine with foam. Just thought I would let you all know this simple fix.
