Holden VN Heads 308 304 Air Gap Dual Plane Carby Intake Manifold Black

Holden VN 304/308 Air Gap Dual Plane Carburetted Intake Manifold, Black

Designed to maximize airflow consistency on carburetted Holden V8s, this Air Gap dual-plane intake manifold in a black finish delivers steady, even air and fuel distribution from idle through mid to high rpm. It’s specifically tailored for late-model VN engines with non-EFI setups and is not compatible with VT factory roller cam engines.

• Air Gap dual-plane configuration to promote cooler air delivery and improved throttle response across the operating range
• Square bore carburettor pad to accept aftermarket square-bore carburettors, compatible with both manual and electric choke options
• Overall height from carb pad to bottom: 165 mm (check bonnet clearance before fitment)
• Port size: 1.19" x 2.09"
• Includes intake manifold gasket: 5REGIM-308VN
• Carburettor studs: 5/16-18" (x4)
• Mounting holes: M6 x 1.00 mm (x4)
• Ports: 1/4" NPT (x1) with steel port plug included; 3/8" NPT (x1) with steel port plug included
• Additional ports: 1/2" NPT (x3) with 2 steel port plugs included
• RPM operating range: 1500–6500
• Specifically designed for Holden 304 V8 engines; will not suit early Holden 308 cylinder heads
• Non-EFI applications only for late-model Holden VN engine models; EFI applications use A6010-4003
• Intake runners should be port matched to your cylinder heads for optimal performance
• In most cases, these manifolds accommodate late-model water necks, air conditioning, alternator, and HEI ignition systems
• Dual Plane configuration for balanced torque across the RPM range

Upgrade your carburetted Holden setup with a purpose-built, heat-conscious Air Gap intake that helps maintain a steady air-fuel flow, delivering improved throttle response and consistent power delivery from idle up to higher RPMs.
