KAD 5-Port Billet 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 is optimised for our 5-port cylinder head package, helping improve airflow and performance. It can also be fitted to other A-Series 5-port heads, although match-porting is strongly recommended to achieve the best results.

Supplied with two O-rings to seal against the underside of the carburettor, 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.
