1990-1991 ZR1 Spark Plug Set ACDelco - OEM Number(s) (19354429)
If your 1990-1991 ZR-1 is starting to feel a little lazy off idle or you’re getting that gut feeling your LT5 is ready for some attention, a fresh set of ACDelco plugs is the easiest win you can give that masterpiece under the hood. These ACDelco 41602 spark plugs are built exactly the way the LT5 likes them, with a copper core that dumps heat fast, a hot-tip insulator that wakes up quickly, and nickel-chrome construction that shrugs off the beating inside a high-revving ZR-1. In plain car-guy terms: they fire hot, stay clean, resist fouling, and keep your ZR-1 running like the legend it is. If you're tuning, refreshing, or just making sure your LT5 stays angry in all the right ways, this is the plug set you want.
