New from Wilson Manifolds are these Iso Tapered Carburetor Spacers. Testing shows a gain of 16-28 horsepower on an American V-8 engine. The increase comes from reduced harmonics that are transferred from the engine into the carburetor float bowls and passageways.

      The Wilson spacer controls these harmonics by isolating the carburetor from the engine vibration allowing for a more consistent and less aerated amount of fuel to be delivered to the engine. The spacers feature a vibration resistant composite construction in both the upper and lower flanges, which can reduce harmful harmonics buy as much as 50%. We found a two inch thick Wilson tapered spacer for a 4150 carb for $188.95. Contact Wilson Manifolds at (954) 771-6216 www.wilsonmanifolds.com
