1997-2004 C5 ACDelco Double Platinum Spark Plug 41-962 - OEM Number(s) (19299585)
This ACDelco spark plug is built to the same standards as the plugs installed at the factory, which means consistent spark, smooth idle, and long service life you can trust. The copper core pulls heat away fast to keep detonation and fouling in check, while double platinum pads on both the center and ground electrodes hold their gap and reduce wear on the ignition system. The fired-in suppressor seal helps keep radio noise down and protects against compression pressures, so you get reliable performance mile after mile. Whether you are doing routine maintenance or chasing that crisp throttle response, these plugs are one of those small upgrades that make a real difference every time you turn the key.
