Changed the original spark plugs and wires at 183k miles

2013 L99, ordered late-2012 and picked up January 2013 with 13 miles. Dynatech headers and Jannetty tune at ~40k miles and a Roto-fab intake at some point later on. Oil changes at 10 - 20% remaining oil life. 93/94 octane all the way. This is my daily driver: it still idled smooth and pulled hard--I wouldn't have changed them if I didn't feel a slight stumble at WOT. I think the plugs look fantastic given their age. I replaced the plugs with AC Delco 41-162s. I replaced the stock wires with AC Delco 9748UUs, even though the originals came off intact. I put the heat shields back on also.

Looks like a nice even color betwixt the plugs.
