Chevy Small Block Carbureted Dual Plane Air Gap Aluminum Intake Manifold - Polished
Unlock the full potential of your Small Block Chevy engine with this dual plane air gap intake manifold, engineered for high-performance street and strip applications. Designed to compete with leading high-performance air-gap style intake manifolds, delivering excellent airflow efficiency, cooler intake temperatures, and strong mid-to-high RPM power.
Why Air Gap Technology Matters
Unlike traditional intake manifolds, the air-gap design creates an open space beneath the plenum, separating intake runners from engine heat. This significantly reduces heat transfer, allowing a cooler, denser air/fuel mixture—a critical factor in increasing horsepower and torque
Performance You Can Feel
The dual-plane layout enhances cylinder distribution, giving you:
- Strong low-end torque for street driving
- Improved throttle response
- High-RPM power up to 6,500 RPM
Built for Street & Performance Applications
Whether you're restoring a classic SBC or building a high-performance 350 or 383 stroker, this intake delivers the perfect balance of drivability and power. Compared to standard dual-plane manifolds, air-gap designs provide improved top-end performance while maintaining excellent street manners
Show-Quality Finish
The polished aluminum construction not only improves heat dissipation but also adds a premium look to your engine bay—ideal for show cars and high-end builds.
