Review on 🚗 K&N Premium Oil Filter: Ultimate Engine Protection for Porsche (918 Spyder, Boxster, 911, GT2, GT3, Turbo, Cayman, Cayenne, Carrera, 996), PS-7011 by Kevin Witherspoon

This is my second K&N in my 2005 997. Works great, almost the same size as the OEM. It might just be me, but I think the oil and entire filter block looked in better condition after the K&N change than it did after the OEM replacement. I also have a K&N air filter. I have trusted their product for many years. If you have a 997 Carrera, this filter is for you. You get an additional 5 hp. +.
