Fit for 4 barrel carbs with a square bore base like the H-olley 4150/4160, Barry Grant, Carter and Edelbrock that are used on many Small/Big Block Chevy, F-ord and C-hrysler M-opar engines.
The phenolic plastic style carb spacer also insulates your carb from excessive engine heat.
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.
Reducing fuel temperature inside the carburetor results in a denser, more powerful fuel charge to the manifold.
