Intakes Designed with Racing in Mind
Holley Split-Design Race Intake Manifolds incorporate a unique feature typically reserved for high-end, custom racing intakes. These manifolds have a split design that allows the intake to be disassembled into two halves for direct access to the internal ports and plenum. The modular plane design of these intakes can accept either a carburetor or throttle body-mounted electronic fuel injection system. All Holley Split-Design Race Intake Manifolds come complete with mounting hardware, O-ring seals and shoulder bolts that hold both halves together.
