What's in the Box

Info

Plastic carburetor spacers reduce the fuel temperature inside the carburetor by insulating the carb from the hot intake manifold. This results in a denser air/fuel mixutre for more power. Four-hole design increases low-end torque compared to open style spacers.

  • Fits 4150 and 4160 series Holley carbs
  • 1-3/4" venturi bores
  • 4 barrel carburetors
  • Gaskets NOT included
