Description
Phenolic spacers are essential for carburetor tuning—they create thermal isolation between your intake manifold and carburetor, reducing fuel vaporization and improving throttle response consistency. This ported R9138 is a direct bolt-on solution that delivers measurable gains in fuel atomization and cold-start performance without requiring any fabrication or modifications.
Built from phenolic composite material, this spacer resists heat transfer better than aluminum alternatives, making it ideal for high-performance applications where intake temperatures can spike. The inclusion of gaskets and hardware means you’re ready to install out of the box.
