Billet Aluminum Flame Arrestor Spacer
Holley 4150 (5.10" I.D. x 7/8" Tall)

These spacers were developed to allow additional throttle linkage arm clearance for use with many aftermarket EFI Throttle bodies. The small spacer is standard equipment on Hardin marine 4150 series flame arrestors. While the larger unit is perfect for raising Dominator/4500 series flame arrestors.
