Carburetors and Other Accessories / Phenolic Spacers

Phenolic spacers are an essential component for carburetors, offering enhanced thermal insulation to prevent heat transfer from the intake manifold to the carburetor. These spacers help to improve fuel atomisation, resulting in more efficient engine performance, particularly in high-performance applications. With various designs available, such as Power Cone options, they cater to a wide range of carburetor models, including the popular Holley 4150 series.
