Great news! If you're using a Holley Gen 3 Dominator, there's no need for a bulky air scoop mount with stands sandwiched under the carburetor. Holley Gen 3 Dominator air scoop mounting adapters bolt directly to the air cleaner flange of the Gen 3 Dominator and provide a solid mounting point for air scoop trays. You'll have no more frustration trying to tune your carburetor around those bulky parts! These adapters are CNC-machined from billet aluminum and are available in clear or black anodized finishes for corrosion protection--and to match the finish of your Holley Gen 3 carburetor.
