corroded spark plugs N43

[pashley300]

Hi people,

I’m running an N43 in my e87 120i. Replaced the spark plugs yesterday after a year and 4 months. OE plugs.

They are pretty terrible and actually look lean to me. Also very corroded for their age.
I’m running e85 with a tune, ethanol burns cleaner. Would that be why the plugs look lean?

What do you think?

Thanks

Not an expert here but all looks fine to me.
