OEM replacement for 2016 5.3 Silverado
Zero complaint with the spark plugs but I have one with the packaging. 8 plugs were sent in the little individual boxes inside of a non padded Amazon envelope. I know packages get thrown around in transit so I was concerned for damage but they were not broken and have been working well.
