I wonder if the iron is high due to many WOT runs

possibly, could be something of that sort. On my cars I see 1ppm or less per 1k but if it goes really high you might have a issue. I did a 15 or 20k cvt fluid analysis using Redline Non Slip and had less than the one ppm. The oil analysis guy at Hotshots was really stunned. Currently at 330k miles on original motor and transmission

So, this is now 31k miles on the replacement engine.

Ever since swapping engines, if you notice the Si readings are much higher.

There seems to be a likely unfiltered air leak somewhere which correlates with higher Iron numbers.

Reading back, you used an aFe Pro Dry S air filter on the now retired engine. Could it be an air filter difference as well? Though, I would be surprised at a Wix air filter issue just commenting on the difference; since air filtration; or a lack thereof, seem to be an issue. This isn’t a rebuilt engine with sealant washing out. Address the possibly ingress of Si and monitor for changes

That's what I'm thinking too @harry j
