The Vibrant adapter flange adapts a 92mm LS DBC throttle body to a 4-inch hardline diameter, providing a precision-machined transition for intake plumbing. It is intended for custom LS intake builds where a 92mm throttle body must mate to a 4-inch duct, supporting clean sealing and consistent bore alignment for turbo or naturally aspirated plumbing projects.
