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.
