I changed my oil for the first time today and when I took the orig. filter off it was an AC PF44 and the owners manual says to use a AC PF 46?? Should I be concerned? The two of them look the same in size so whats the difference? I may just be paranoid!

Do a search on this, it's been spoken about. All the 46 is, is an update to supercede the 44 for whatever improvements they deemed necessary. If you still have a stock of 44's (like I do), you aren't hurting anything though.

Either or, don't worry about it.

I figured they were almost the same thing. Thanks all!
