If changing your oil you can use the 7.3 D.I. filter ( motorcraft # FL-1995 ) for more filter substrate and oil capacity too.

That's an EXCELLANT suggestion, I have done exacatly that since the PSDs were introduced, use the larger PSD filter on the IDI engines.

The Wix/NAPA PSD filters (51734/1734) also filter out smaller particles than the IDI filters (51742/1742.)
