Decided to change out the sparkplugs on my Wife's 2016 Malibu 1.5 liter engine since it was way overdue.
110,000 miles on the original plugs. Supposed to change at 60,000 miles. that's on me.
Old ACDELCO 41-123 New Plugs are ACDELCO 41-156. Don't know why they changed the part number but that's what the parts stores say is OEM now.
Anyway, interesting disk shaped deposits. Never seen anything quite like it before.
