Phenolic Spacers

Phenolic spacers are used between the carburetor and intake manifold to reduce heat transfer and improve performance consistency, especially in high-temperature conditions. A phenolic carb spacer acts as a thermal barrier, helping to keep the air-fuel mixture cooler as it enters the engine, which can contribute to increased power and reduced vapor lock. The phenolic carburetor spacer is particularly valued in motorsports and street applications for its ability to isolate the carb from engine heat. Made from durable phenolic carb spacer material, these components offer excellent resistance to heat soak without compromising structural integrity. The choice of carb spacer height and type can also influence air and fuel distribution, making a phenolic spacer a practical tuning tool for optimizing throttle response and overall engine efficiency.
