I recently purchased the Fram Endurance FE7317 for my 3.5 V6 Accord and the FE3980 for my 350 Vortec. Overall all what's the verdict on the Endurance? I noticed the FE7317 has an open plastic center tube exposing the wire backed media. The FE3980 has the tiny louvers center tube. Not sure why the difference. I'm now nervous about using louvers so I think I'll return it. But how about the FE7317 with the open plastic center tube? Think this is a good filter? Trying to find the best oil filters to replace my old quality Wix stash that is about out. Thanks for the help!
