Rather than this be part of another thread, I thought I'd post it seperate, so that it would not get lost.

Here's what I came up with. the 318 filter idea is a bust, because there's no room around the filter perimeter for any more filter. There's just too much motor in the way. The standard WIX OEM replacement is #51348, it's on the left. The larger one, #51315, on the right. All specs provided by the WIX filter web site.

You can see in this picture, that the gaskets are nearly indentical. The only noticable difference in the specs is the by-pass valve setting. I don't think it's enough of a difference to worry about. The longer filter is a touch larger in diameter, and almost 1.5" longer. I think anytime you can swap out for a larger filter with a greater capacity, it's a good thing.

Thanks! had somebody mentioned something about that in the other thread where they ignored me, I wouldn't have started a whole new thread.
