How do these look for 30k miles?

[Pistol_91]

Stock o2s and plugs. Passenger side plugs seemed to have a little oil on the threads. Anybody else experience this? Btw the f150 o2s don't reach with the long tube headers I have on the driver side. Unless you're comfortable with the wire being a few inches away from the header.

Tune looks a little rich to me, and Yes the oil up on threads is normal.

What you don't want to see is oil getting caked on the electrode.

I wonder if our catch cans help reduce the oil that's seen on the plug threads?

Yes, I agree. Looks like I don't have any leaks from the top side which is good. Def a bit rich, but overall, for 30k miles going through 93, e85, N/A to boosted. I'm pretty happy with what I see. Lol...

I would think yes.

I recently replaced the O2s at 35k for maintenance. Was curious to see if id have a change in fueling but not one bit. With fasoc turned off.

O2s look similar to mine. Same progression, 93-e85-boost

Awesome. Yeah I haven't noticed any difference today on fuel trims or anything. Stock ones were probably just fine.
