Carburetor spacers are a great tuning tool.

Depending on which specific carb spacer (or multiple spacers) you choose, you can add extra horsepower, particularly in the mid and upper rpm ranges. You can also adapt different carburetors to different intakes, so you can test out different combinations.

It all comes down to the type of spacer you use.

PowerNation and Summit Racing created this carburetor spacer “show and tell” video to help you pick the right spacer for your engine. In less than one minute, you’ll find out essentially everything you need to know about spacer design, height, and materials.
