2006-2013 C6 ACDelco Iridium Spark Plugs - LS7 and LS9 - OEM Number(s) (12571165)
If you’re running an LS7 or LS9 Corvette, you already know these engines don’t mess around, and neither should your spark plugs. Modern iridium plugs last way longer than the old-school stuff, but when it’s finally time to swap them out, sticking with the correct ACDelco iridium plugs keeps your Vette firing clean, strong, and ready to bark at every throttle blip. Iridium is tough enough to survive a small war, which means a smaller electrode, better cold starts, quicker acceleration, and less load on your ignition system. In short, these plugs do their job so well you almost forget they’re there, and that’s exactly why they're important. When the day comes to change them, do your LS a favor and use the plugs it was born to run.
