X-AVION 4150 series spacers are CNC machined from billet 6061 aluminum, light weight but durability.
The 4150 carburetor spacers can isolate carburetor from manifold, preventing horsepower-robbing heat transfer while also increasing air flow due to the increase in distance from the bottom of the carburetor to the manifold plenum, allow the air and fuel mixture to turn more easily into the runners.
Four hole spacers are additionally offered with specially increase of air velocity under the carburetors, will provide optimum power and distribution.

It was an okay product, the throttle bores are huge, larger than most carburetors.
