350 Stage 1 Dual-Plane Intake Manifold

The TA Performance 350 Stage 1 Intake Manifold is engineered to unlock the untapped performance of the 350 Buick engine. Introduced in 1983, this dual-plane aluminum manifold was TA Performance's first product, designed to address the lack of high-performance intake options for this engine. Its proven dual-plane runner design significantly enhances engine efficiency and economy, providing a perfect complement to street and strip applications. The Stage 1 manifold excels at balancing performance across the RPM range. It maintains excellent low-speed and mid-range torque for superior driveability while simultaneously boosting top-end power. The manifold is precisely machined to accommodate a wide array of carburetors, including Quadrajet and other spread bore carburetors, as well as square bore options like Holley, Edelbrock, and Demon, ensuring versatile application. Performance gains from installing this manifold are substantial. It delivers an estimated 15-35 HP increase depending on the overall engine combination, and improves torque and power output from 0 to 6500 RPM. Furthermore, it contributes to a lighter overall engine assembly by reducing weight by 40 lbs. The manifold also offers improved fuel economy and better throttle response, making it a versatile upgrade for various driving needs. Designed for practicality, the TA Stage 1 Intake Manifold works with GS Ram Air systems and stock air cleaners, clearing the hood even with all stock air cleaners installed. It is stated to fit ALL 350 Buick engines, offering broad compatibility for enthusiasts looking to enhance their Buick 350.
