Enhanced Vantage Manifold Set for Aston Martin DB4, DB5, DB6, and DBS6

Elevate the performance of your classic Aston Martin with our meticulously re-engineered Vantage manifold set. Designed specifically for 3.7L and 4.0L 6-cylinder engines, this set bridges the gap between factory original and high-performance upgrades, offering a simplified “Vantage conversion” that delivers superior drivability and power.

Precision Engineering for Optimal Performance

We have utilized modern manufacturing technology to address original factory limitations, ensuring these manifolds provide a seamless fit and improved airflow.

• Bolt-On Performance: Our manifolds feature CNC-machined ports with an improved size and shape. This allows for a “plug-and-play” Vantage conversion on standard SU 1.5″ port cylinder heads, eliminating the need for expensive or invasive cylinder head porting.

• Universal Compatibility: Whether you are running a standard head, an original large-port Vantage cylinder head, or a later 6-cylinder model, our design ensures a perfect seal and zero loss in airflow.

• Refined Throttle Response: The optimized port layout enhances engine breathing, leading to sharper throttle response and smoother overall drivability.

• Efficiency Gains: We have specifically optimized the brake vacuum port area to minimize turbulence, maximizing vacuum efficiency.

Compatibility

This manifold set is designed to fit the following 6-cylinder models:

• Aston Martin DB4, DB5, and DB6

• Aston Martin DB6 Mk2
