APD 4150 Series Billet Enforcer Carburettor.
These carbs are a true work of art and provide unmatched throttle response and efficiency. The entire carby is CNC machined from billet aircraft grade aluminium and anodised black for durability.
 
The Billet Enforcer street carbs come standard with primary power valve for cleaner cruising mixtures, the rear is plugged and secondary jet extensions are fitted to ensure fuel delivery under hard acceleration.
 
All APD Billet Enforcer street/ drag carburettors feature the APD billet fuel bowl standard. Primary power valves help street driveability along with secondary jet extensions and notched float for hard drag launches.
