90 Degree oil filter adapter for 5.9 Magnum
I'm not trying to fill up your want ad with unnecessary posts, but I think you're going to run into issues trying to run a 90* adapter on a Magnum. The 90* adapter was designed for the LA series, and the Magnums have slightly different machining in the filter area- the heights of the two sealing/gasketed areas are not the same between the two engine families. Even the flat filter plates are different between the two. Using the 90 on a Magnum can result in leakage onto your headers or worse. There may be a workaround that I'm not aware of...
If header clearance is your primary concern, then consider using a shorter oil filter- usually a Wix 51085 will clear the headers, but in extreme cases you may need to go to a Wix 51335- the darn thing looks like a hockey puck, but usually fits where nothing else will.
I usually like to run as big of a filter as I can, but sometimes you have to make concessions and just change the filter more often.
