KAD A-Series Billet Inlet Manifold

KAD Billet Inlet Manifold for A-Series 5-Port Cylinder Heads Developed over several seasons of racing, the KAD billet inlet manifold is designed to deliver maximum performance from our CNC-ported A-Series racing cylinder heads running a Weber DCOE carburettor. Machined from billet for accuracy and consistency, this manifold helps to improve airflow and performance on any A-Series engine, although match-porting is strongly recommended to achieve the best results. Supplied with two O-rings to seal against the carburettor, removing the need for the unreliable misab seals. This is a proven race-developed upgrade for serious A-Series engine builds. An optional drill jig is also available to help ensure accurate alignment to your cylinder head. Simply align the jig with the ports in the head, then drill through it to position the dowel holes correctly so the manifold locates precisely on your cylinder head. Available in two sizes measured at the port entry into the cylinder head.
