VW phenolic carburetor spacers. Works with Weber IDA carburetors. Available in black and brown. Includes 8 gaskets and 4 spacers. They insolate the carburetor from engine heat to prevent fuel from boiling (vapor lock) and helps increase performance by creating a cooler, denser air/fuel mixture. They also add plenum volume, which can be used to tune engine performance characteristics like torque and horsepower.
Lower thermal conductivity than aluminum
Denser fuel/air mixture
Increased plenum volume
