Isolated air gap design keeps the intake runners cool to optimize combustion efficiency.
Specifically matched to suit classic holden v8 304 and 308 engines using vn-style cylinder heads.
Dual-plane architecture delivers exceptional low-to-mid range torque for daily drivability.
The Calflow Crosswind dual-plane intake manifold is engineered to suit Holden V8 304 and 308 engines fitted with VN-style cylinder heads. This high-flowing street manifold features an isolated air gap design that keeps the air-fuel charge cool by separating the runners from the hot engine valley. It delivers exceptional low-to-mid range torque and crisp throttle response.
