2005-2013 ACDelco Spark Plugs for Edelbrock E-Force Supercharged Engines - OEM Number(s) (19354421)
If you’re running an Edelbrock E-Force on your Corvette, you already know boost turns everything up a notch, and your spark plugs need to keep up. That’s where the ACDelco R42LTS plug comes in. Think of it as the unsung hero under the hood, quietly keeping every cylinder lit no matter how much air that blower shoves in. With a copper core that pulls heat away like it’s clocking overtime, a hot-tip insulator that fires up fast, and nickel-chrome alloy that laughs in the face of combustion-chamber nastiness, these plugs give you clean, reliable spark without the drama. They’re built for consistency, they play nice with boosted applications, and if you’re tired of low-speed fouling or sluggish performance, swapping in a fresh set of R42LTS plugs is one of those cheap, satisfying fixes every Corvette guy appreciates.
