Description
The Hornet-518 is Halltech’s next-gen cold air intake built for C8 Corvettes, designed to unlock engine breathing potential without ECU tweaks. With a molded velocity stack and oversized filter area, it enhances flow dynamics while preserving OEM routing and component reuse. Installed in the stock intake location, it gives your Stingray a stronger intake sound and more usable power under load.
