110077 - Barry Grant Aluminum Spacers

BG billet aluminum spacers provide a valuable tuning tool by changing the relationship of the intake manifold and carburetor. Open spacers increase plenum area, aiding in developing power in mid- to upper-rpm ranges. 4-Hole spacer can have a positive effect on torque and power in the low- to mid-rpm ranges. BG Billet Spacers are available in 4150- and 4500-styles and in standard or lightweight versions, 1/2" or 1" thickness.
