Carburettor Phenolic 2" 4 Hole Spacer Gaskets and Mounting Hardware

Aeroflow’s Carburettor Phenolic 2" 4-Hole Spacer is designed to sit between your carburettor and intake manifold, delivering precise fuel and air delivery precisely where you need it. The kit includes gaskets and mounting studs, with mounting hardware included in all variations for straightforward, reliable installation. Key benefits that matter on the track and in the street: - Improves air/fuel distribution across the intake for a more consistent charge, boosting throttle response and overall engine performance. - Acts as a thermal barrier, reducing fuel temperature to yield a denser fuel mixture and stronger combustion. - Helps reduce vapor lock in hot or prolonged idle conditions by stabilizing the fuel charge before it enters the carburettor. - Adds plenum volume to enhance manifold resonance and flow characteristics, contributing to stronger low- and mid-range torque. - Improves linkage clearance on aftermarket or custom throttle cable setups, reducing interference and binding. - Phenolic spacers block heat transfer more effectively than many materials, with a thermoset plastic core that serves as a heat sink between the intake and carburettor. - With a harder material, these spacers resist warping through heat cycles, maintaining a consistent gasket seal and alignment. Material and design notes: - Phenolic 2" spacer profile provides a robust, heat-resistant barrier between components. - Available in different heights and in either open or ported designs to suit 4150 square bore manifolds, offering flexible fitment for a range of setups. What’s included: - Gaskets - Mounting studs - Mounting hardware (included in all variations) Compatibility and design specifics: - Specifically designed for 4150 square bore manifolds with a 2" spacer profile and a 4-hole pattern. - Open or ported design options are available to match your airflow goals and manifold configuration.
