◆Principle and Function:Carb spacers extend the length of the intake mixture column, which improves air/fuel distribution.As a general rule, the open design spacers increase plenum volume for improved high rpm power, while 4-hole designs increase mixture velocity for improved low-speed and mid-range torque.They also help to insulate the carburetor from engine heat and provide clearance for linkages.
◆Carburetor Spacer Thickness: 2 inch
◆High Quality Material:Our carburetor gasket kit are made of aluminum alloy material, durable for long term use. Phenolic plastic will help keep heat out of the carburetor equaling more horsepower.
