A couple of months ago, oil filters were a hot topic on this forum with many members ripping open new filters to see if there were cotton and bugs installed!

It was a very long thread that wandered on and off topic!

I never did get the overall consensus, or conclusion, as to which filter ended up being the best choice.

With that said, I'm needing to change my oil soon and need to know which oil filter is best for my 603?
