Which spark plugs for 2010 LLT?
My pdf copy of the owner's manual says ACDelco 41-990, which is a Professional Platinum plug. Most online resources say the OEM is the Iridium 41-109. Which is correct????

Thanks.
$5.69 each at Rock Auto and there's a $3 per plug mail in rebate. Cheap maintenance. Love it! Rob |
