Get the maximum power from your carburetted engine with this Air Gap Holden carburetted cast intake manifold. This dual-plane intake manifold is designed to keep your air and fuel distribution going into the engine at a steady and even flow for maximum performance and efficiency. The carburettor-mounting pad is designed to accept aftermarket square-bore carburettors with either manual or electric choke options available on today’s market. Specifically designed for Holden 304 V8 engines operating from idle to 5500 rpm range. In most cases, these manifolds accept late model water necks, air conditioning, alternator and H.E.I. ignition systems.

Intake Runners should be port matched to your cylinder heads for optimal performance.

• Fits Holden 304 V8 Engines. Will not suit early Holden 308 cylinder heads. This is designed for late model Holden VN Engine Models EFI models only. Use A6010-4000 for NON-EFI applications.
• This intake manifold does not work with factory OEM fuel rails and requires the use of Aeroflow Fuel Rail Kit included (AF6999-4003).
• Requires the use of 14mm short (33.60mm) fuel injectors (Sold Separately).
• Dual Plane Configuration.
• RPM operating range - 1500 to 6500.
• Natural Cast Finish.
