Wix makes very nice oil filters, but if you use them you must obtain a new o-ring seal from somewhere else -- the one included in the box never fits and I've cut nearly every one I tried to use.
Peter I concur with the assessment of the o-ring...never could get the new one to seal so I just re-used the Mann one I had in there. Only reason I tried it in the first place was I ran out of the Manns and didn't have time to shoot an order off to Rusty. I now have a years supply on the shelf, and no more WIX....
