Hello All
I have yet to do any performance upgrades on my C7. Intake and plug wires are first I think.
Has anyone installed aftermarket plug wires and seen gains/benefits? I have researched Granatelli and can't decide if they are worth the money. The MSD wires are half the price but don't advertise the "huge" gains (11+ HP) that Granatelli does.
Any help is appreciated
